Wide Workload Coverage

The Transmille 3041A has been developed to reduce the number of individual standards required in an electrical calibration laboratory.

Transmille states that the 3000A Series can provide calibration capability for up to 18 different instrument types, depending on configuration.

The standard electrical functions already cover a broad range of calibration requirements.

Additional internal options and external adapters allow the system to be tailored to the specific workload of the laboratory.

This modular concept means that a laboratory can start with the required core functions and expand the system when additional calibration capabilities are needed.

Precision DC Voltage Calibration

DC voltage is one of the core functions of the Transmille 3041A.

The calibrator generates DC voltage from low-level signals up to:

±1000 V

with best one-year total accuracy of:

±25 ppm

This performance makes the 3041A suitable for calibration of high-quality digital multimeters as well as a wide variety of general electrical measuring instruments.

Typical applications include calibration of:

• Handheld multimeters
• Bench multimeters
• Digital voltmeters
• Analog voltmeters
• Panel meters
• Data acquisition systems
• Process measurement equipment

The broad output range allows low and high voltage ranges of suitable instruments to be calibrated using one source.

DC Current up to 30 A

The Transmille 3041A provides direct DC current generation up to:

±30 A

with best one-year total accuracy of:

±50 ppm

Direct 30 A capability is particularly useful for multimeter calibration because high-current ranges can be tested without an additional current amplifier for many common workloads.

This reduces setup complexity and the number of external devices required on the calibration bench.

AC Voltage up to 500 kHz

The Transmille 3041A provides broad AC voltage capability.

AC voltage extends from approximately:

20 mV to 1000 V

with frequencies from:

10 Hz to 500 kHz

on applicable ranges.

Best one-year total AC voltage accuracy is specified down to approximately:

0.04 %

depending on voltage and frequency.

The combination of wide voltage and frequency coverage enables calibration of AC functions on a broad range of digital and analog multimeters.

AC Current up to 30 A

The Transmille 3041A also generates AC current from approximately:

20 µA to 30 A

over frequencies from:

10 Hz to 10 kHz

with best one-year total accuracy down to approximately:

0.06 %

depending on range and frequency.

The broad current range enables both low-current and high-current ranges of suitable electrical instruments to be calibrated directly.

Resistance up to 1 GΩ

Resistance calibration is integrated into the Transmille 3041A.

The passive resistance capability extends to:

1 GΩ

with best one-year total accuracy down to:

40 ppm

for applicable ranges.

This broad resistance capability enables calibration of resistance functions on:

• Digital multimeters
• Bench multimeters
• Resistance meters
• Process instrumentation
• Electrical test equipment

The 1 GΩ upper range provides significantly broader resistance coverage than many general-purpose multifunction calibrators.

Capacitance Calibration

The Transmille 3041A provides passive capacitance values from:

1 nF to 10 µF

with best one-year total accuracy of approximately:

0.25 %

for applicable values.

Capacitance capability allows suitable multimeters and capacitance measuring instruments to be calibrated without requiring a completely separate capacitance standard for the standard workload.

Optional functions can further extend the capacitance capabilities of the platform.

Frequency Generation up to 10 MHz

Frequency generation is available from:

1 Hz to 10 MHz

with standard best one-year total accuracy of:

20 ppm

For laboratories requiring improved frequency performance, Transmille offers an optional high-stability frequency output with accuracy down to:

1 ppm

This makes the 3041A suitable for calibration of frequency functions on multimeters, process instruments and suitable frequency measuring equipment.

Thermocouple Calibration

The Transmille 3041A supports a broad range of thermocouple characteristics.

Supported thermocouple types include common industrial types such as:

J, K, T, R, S, B, N and E

as well as additional supported characteristics.

Best one-year total performance is specified down to approximately:

±0.09 °C

for applicable thermocouple types and conditions.

The optional external thermocouple adapter provides an effective method for thermocouple simulation and measurement while placing the cold junction close to the device under test.

Calibration of Digital Multimeters

One of the primary applications for the Transmille 3041A is digital multimeter calibration.

A modern digital multimeter can include:

• DC voltage
• AC voltage
• DC current
• AC current
• Resistance
• Capacitance
• Frequency
• Temperature

The 3041A covers these core quantities from one calibration platform.

This can significantly simplify calibration procedures compared with using separate standards for every measurement function.

Calibration of Analog Instruments

The Transmille 3000A Series is not limited to modern digital instruments.

The platform has sufficient output capability to drive many older analog instruments.

This is important for calibration laboratories that maintain a mixed workload containing both modern digital measurement equipment and legacy analog devices.

The Transmille 3041A therefore provides a practical solution for laboratories with a diverse electrical calibration workload.

Optional Power Calibration

The workload of the Transmille 3041A can be expanded with the PWRSINE option.

This option enables calibration of power and wattmeters by dynamically controlling the phase relationship between voltage and current outputs.

For more advanced power quality applications, the PWRDDS option expands this functionality with the ability to simulate:

• Harmonics
• Distortion
• Dropouts
• Flicker
• Custom waveforms

This allows the 3041A platform to be configured for considerably more advanced power measurement calibration.

Optional Oscilloscope Calibration

The Transmille 3041A can also be expanded for oscilloscope calibration.

Transmille offers internal oscilloscope options for the 3000A platform.

For the 3041A, options are available to extend the workload into oscilloscope calibration, including bandwidth-related applications.

This allows a laboratory to combine conventional multimeter calibration and oscilloscope calibration within the same multiproduct platform.

Optional Inductance

For laboratories calibrating LCR and RLC meters, Transmille offers an internal inductance option.

The option provides eight precision inductance values covering:

1 mH to 10 H

Intermediate values include 19 mH and 29 mH, which can be useful for linearity checks.

Adding inductance capability further expands the range of instrument types that can be calibrated with the 3041A.

Optional Precision PRT Output

A precision four-wire PRT output is also available for the 3000A platform.

This option is designed for compatibility with both DC temperature measuring instruments and AC bridges.

It provides another route for expanding the Transmille 3041A beyond conventional electrical calibration.

Variable Resistance and Capacitance

The optional SIMRC function adds variable resistance and simulated capacitance outputs.

This provides greater flexibility than the passive standard values included with the base instrument.

Variable outputs are particularly useful when a calibration procedure requires specific test points rather than only fixed passive standard values.

Picoampere Calibration

Modern high-performance multimeters increasingly include very low current ranges.

Transmille offers an external picoamp source adapter for the 3000A Series.

The adapter provides accurate current generation at picoampere levels and is designed for calibration of sensitive low-current measuring instruments.

It can be controlled from the calibrator or used as part of an automated ProCal procedure.

High-Resistance Measurement

External accessories can also expand the system into very high resistance and low-current applications.

Transmille offers accessories capable of measuring high resistance values up to:

1 TΩ

and very low currents with picoampere-level resolution.

This modular approach allows the 3041A platform to cover specialist calibration applications without permanently integrating every function into the main calibrator.

Environmental Measurement

The optional Transmille environmental measurement adapter can measure laboratory conditions such as:

10 % to 90 % relative humidity

and:

0 °C to 50 °C temperature

Environmental data can be useful in calibration laboratories where temperature and humidity need to be recorded as part of the calibration process.

Automated Calibration with ProCal

The Transmille 3041A is supported directly by ProCal Version 6.

Transmille also lists automatic uncertainty support for this model.

This allows calibration procedures to control the calibrator automatically and use its specification data as part of uncertainty-related functions within the software.

Automated calibration can help:

• Increase calibration throughput
• Reduce repetitive manual operations
• Reduce transcription errors
• Standardize calibration procedures
• Improve consistency
• Simplify measurement data collection

This is particularly valuable for laboratories processing large numbers of similar instruments.

Flexible Laboratory Integration

The Transmille 3041A can be used as a standalone laboratory calibrator or integrated into an automated calibration system.

USB connectivity supports modern computer-controlled calibration systems.

GPIB and RS232 options are also available for laboratories that need compatibility with existing automation infrastructure.

Rack mounting solutions are available for integration into fixed calibration systems.

I-Guard Output Protection

The current Transmille 3000A platform includes the manufacturer’s I-Guard output protection system.

This provides protection for the calibrator outputs and is particularly useful in busy calibration environments where instruments are connected and disconnected frequently.

Output protection helps reduce the risk of damage caused by incorrect connections during routine calibration work.

3041A Compared with the 3010A and 3050A

The Transmille 3041A occupies the middle position within the 3000A Series.

The 3050A provides best DC voltage accuracy of approximately:

50 ppm

while the 3041A improves this to:

25 ppm

and the 3010A provides approximately:

8 ppm.

The 3041A also provides direct current output up to:

30 A

compared with 22 A for the 3050A.

Resistance extends to:

1 GΩ

compared with 100 MΩ on the 3050A.

The 3010A also provides 30 A and 1 GΩ capability but offers higher accuracy for demanding laboratory applications.

The 3041A therefore provides a strong balance between precision, workload coverage and system capability within the 3000A Series.
