Voltage function adjustment (DC and AC)
The ranges for DC voltage (DCV) adjustment are 100 mV, 1 V, 10 V, 100 V, and 1000 V. For AC
voltage (ACV) adjustment, the ranges are 100 mV, 1 V, 10 V, 100 V, and 750 V RMS at 1 kHz.
Do not apply more than 1000 V (peak) to the Model 2110. Applying excess voltage may
damage your Model 2110 and create a shock hazard that could result in injury or death.
To eliminate the thermal EMFs due to the differences between two metals, use copper leads to
connect your source signal to the DMM.
DCV range adjustment
1. Set the Model 5700A for 0 V DC using AUTO RANGE. Set the output to the STANDBY mode.
2. Using shielded, low thermal EMF cables, connect the Fluke 5700A output HI and LO to the Model
2110 input HI and LO terminals. Allow connections to stabilize for a minimum of five minutes
before proceeding.
3. Set the Model 2110 to the 100mV DC voltage range by sending the following command:
CONF:VOLT:DC 0.1
4. Set the Model 5700A output mode to OPERATE.
5. Adjust the input offset by sending the following command:
CAL:PROT:DC:STEP 1,0
6. Wait until the following message is displayed on the Model 2110:
Cali OK
