Current Sourcing Test
1. Put the calibrator in Standby (STBY) mode.
2. Connect the SOURCE + (A) and − (mA) terminals on the UUT to the current
terminals on the multimeter as shown in Figure 3.
3. Put the multimeter in the dc mA mode and manually select the 100 mA range. (Do
not allow the multimeter to autorange.)
4. Turn the UUT rotary switch in the OUTPUT
X position.
5. Use the SpanCheck, %STEP and COARSE keys on the UUT to apply the values
