Note: In 2-wire resistance measurement the V--Hi plug may not be
connected to the Sense-Hi plug.
6.10 Calibration of AC Voltage
An offset correction has to be proceeded for all ranges as described for the DC voltage.
Calibration of AC Voltage measurement is carried out without DC Voltage coupling.
The AC Voltage ranges should be calibrated with a Sine Voltage that has a frequency of
1kHz.
The same calibration factor is transferred for the AC Voltage function with DC
Component.
In all other ways, you can proceed as with DC Voltage calibration.
6.11 Calibration of DC and AC Current
An offset correction should be carried out with open connectors. During AC Current
calibration, only the function for AC Current without DC Component is calibrated.
The reference currents shall consist of DC current for the DC Current function, and of
a 1kHz Sine Current for the AC Current function.
Notice: In the 2A range, the calibration current must not exceed 1A.
6.12 Calibration of Temperature
1. Preparations
a) Warmup-period: The DMM 5017 to be calibrated should have run for at least 1h.
2. TEMP-Function: ZERO Offset Correction
a) Insert a four-wire shorting-bridge at the input of the DMM5017, i.e. shorten the four
DMM 5017 Volt/Ohm-inputs - Sense and Source - HI against LO and both pairs
against each other.
b) On the DMM5017 select 1sec integration time and press the TEMP-button. The
DMM5017 will then display ‘Sensor ?’, because ZERO Ohms as sensor input is not
