Step 3: Perform Channel #2 (charger channel) calibration steps
1. Connect the OUTPUT #2 SOURCE, SENSE, and DVM IN terminals to the DMM. Use
the same general connections shown in Figure 14-1 except make all connections to the
OUTPUT #2 terminals.
DMM input connections:
HI: SOURCE +, SENSE +, and DVM IN +
LO: SOURCE -, SENSE -, and DVM IN -
2. The Model 2306 will prompt you to set the full-scale Channel #2 output voltage:
CAL VOLTS CHAN 2
SET 14.0000 V
3. Use the edit keys to set the voltage to 14.0000V, then press ENTER.
4. The unit will prompt you for the DMM reading, which will be used to calibrate the
Cha
nnel #2 full-scale output voltage:
CAL VOLTS CHAN 2
READ1 14.0000 V
5. Using the edit keys, adjust the Model 2306 voltage display to agree with the DMM volt-
age reading, then press ENTER. The unit will prompt for another DMM reading, w
hich
will be used to calibrate the full-scale Channel #1 measurement function:
CAL VOLTS CHAN 2
READ2 14.0000 V
