    Model 4610M Verifi cation & Calibration Manual 3.9. Simulated Resistance - 2 Wire Compensated (Optional) To verify that 2 Wire Compensated Resistance operates within specifi cations, optionally perform the following measurements. Ensure that a multimeter Zero is performed at the terminals as compensated ohms provides a corrected output at the point of connection to the terminals, not at the end of the leads.

    Passive Capacitance Using an LCR meter, configure to perform measurements with a frequency of 1kHz. All passive outputs of the 4610M are measured with a 1kHz frequency. Measuring at a different frequency is possible but it must then be noted that this was the Calibration Frequency. Perform a Zero/Null of the LCR meter with the leads disconnected from the calibrator, but open circuited.

    Either use a pre-characterized handheld multimeter or using a known DC current source and an oscilloscope. Further instructions are available from Transmille upon request. Ensure that the handheld meter that the meter has had a Zero/Null process performed prior to performing measurements to avoid offsets from the meter being introduced into the verification.

    Model 4610M Verification & Calibration Manual 3.12. Thermocouple Source Verifying the thermocouple source requires a multimeter and a neutral Copper/Copper Mini TC-Plug The primary verification consists of confirming the divider ratio at 0mV, +100mV and -100mV, as the thermocouple table is contained within the firmware and does not change with time. To measure the output, set the Thermocouple to 1mV’C type and set the Cold Junction to manual and 0’C Check the measurement in mV as measured with the multimeter against the table of points below.
