Model 2001 DMM
Connect the OUTPUT #2 SOURCE, SENSE, and DVM IN terminals to the DMM. Use
the same general connections shown in
OUTPUT #2 terminals.
DMM input connections:
HI: SOURCE +, SENSE +, and DVM IN +
LO: SOURCE -, SENSE -, and DVM IN -
The Model 2306 will prompt you to set the full-scale Channel #2 output voltage:
CAL VOLTS CHAN 2
SET 14.0000 V
Use the edit keys to set the voltage to 14.0000V, then press ENTER.
The unit will prompt you for the DMM reading, which will be used to calibrate the
Channel #2 full-scale output voltage:
CAL VOLTS CHAN 2
READ1 14.0000 V
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, which
will be used to calibrate the full-scale Channel #1 measurement function:
