Transmille 3200B is an efficient electrical test equipment calibrator designed for fast, safe and accurate calibration of insulation testers, loop testers, RCD testers, multifunction installation testers and PAT testers. By combining the functions normally provided by several individual standards into one benchtop calibration system, the 3200B significantly simplifies the calibration of electricians’ test equipment.
Transmille developed the 3200B specifically for electrical safety and installation test equipment. Traditional calibration methods can require multiple resistance standards, current measurement equipment, voltage sources and direct connections to mains voltage. The 3200B integrates these functions into a dedicated calibration platform designed to reduce setup time and improve operator safety.
According to Transmille, calibration of a typical multifunction electrical tester can be reduced from approximately 45 minutes to under 15 minutes when using the 3200B. The instrument is also designed to achieve a 4:1 Test Uncertainty Ratio (TUR) when calibrating suitable electricians’ test tools.
A dedicated localized mains socket on the front panel allows loop and RCD testers to be connected using their normal mains plug. This eliminates the need to make mains connections using individual 4 mm test leads and crocodile clips, reducing operator exposure to potentially hazardous connections.
The Transmille 3200B supports continuity resistance, continuity current, insulation resistance, AC voltage, loop resistance and numerous PAT tester functions. Optional accessories extend the system to high-voltage insulation testers and HiPot or breakdown testers.
At europascal, we provide professional calibration equipment for electrical measurement and electrical safety testing. The Transmille 3200B provides an efficient solution for calibration laboratories that regularly calibrate electricians’ multifunction testers, insulation testers, RCD testers and PAT testers.

available for applicable configurations.
This provides the resistance standards required to verify common insulation resistance testers and multifunction installation testers.
Insulation Test Voltage Measurement
In addition to resistance calibration, the 3200B can measure the test voltage generated by an insulation tester.
This is important because a complete calibration should evaluate not only the displayed insulation resistance but also the test voltage used to perform the measurement.
The integrated functionality reduces the need for separate high-voltage measurement equipment for common insulation tester workloads.
AC Voltage Output
The Transmille 3200B provides an AC voltage output covering:
100 V to 400 V
