Model 2308 Portable Device Battery/Charger Simulator User’s Manual
Section 13: Calibration
Step 3: Perform charger channel calibration steps
Figure 13-4
Charger channel connections for voltage calibration
1. Connect the OUTPUT #2 SOURCE, SENSE, and DVM IN terminals to the DMM as shown
in
Figure 13-4
.
DMM input connections:
HI: , SENSE +, and DVM IN +
LO: SOURCE -, SENSE -, and DVM IN -
2. The Model 2308 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 Channel #2
full-scale output voltage:
CAL VOLTS CHAN 2
READ1 14.0000 V
5. Using the edit keys, adjust the Model 2308 voltage display to agree with the DMM voltage
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:
CAL VOLTS CHAN 2
READ2 14.0000 V
6. Using the edit keys, adjust the display to agree with the new DMM voltage reading, then
press
ENTER
. The unit will prompt for Channel #2 DVM full-scale calibration:
CAL DVM CHAN 2
ALL READY TO DO?
7. Press
ENTER
to complete Channel #2 DVM full-scale calibration.
8. Connect the digital multimeter volts input and characterized 4
Ω
resistor to the Model 2308
OUTPUT #2 SOURCE terminals using the same general connections shown in
Figure 13-2
.
Be sure to observe proper polarity ( to DMM INPUT HI; SOURCE - to INPUT
LO).
9. Be sure the digital multimeter DC volts function and auto-ranging are still selected.
