The unit will prompt you for the DMM reading, which will be used to calibrate the
Channel #1 full-scale output voltage:
CAL VOLTS CHAN 1
READ1 14.0000 V
Using the edit keys, adjust the Model 2306 voltage display to agree with the DMM
voltage reading, then press ENTER. The unit will then prompt for another DMM
reading, which will be used to calibrate the full-scale Channel #1 measurement function:
CAL VOLTS CHAN 1
READ2 14.0000 V
Using the edit keys, adjust the display to agree with the new DMM voltage reading, then
press ENTER. The unit will prompt for Channel #1 DVM full-scale calibration:
CAL DVM CHAN 1
ALL READY TO DO?
Press ENTER to complete Channel #1 DVM full-scale calibration.
Connect the digital multimeter volts input and characterized 4Ω resistor to the
Model 2306 OUTPUT #1 SOURCE terminals, as shown in
observe proper polarity (SOURCE + to DMM INPUT HI; SOURCE - to INPUT LO).
Be sure the digital multimeter DC volts function and auto-ranging are still selected.
