1. Calibrate the offset voltage of the ULTRASTAB SATURN before using
it for the current calibration. Press “
Null
” and the DVM panel digits
will reset and show “Math” for the current calibration.
2. Key in at least 5 digits for each calibration point to ensure the Power
Supply accuracy after calibration.
3.3.7.3.3 Calibration Procedure (Example: Model 62150H-600)
1. Set the Electronic Load to CV mode 48V.
2. In the CALIBRATION page, press “ ” or turn the “Rotary” ( ) knob to set
CHOICE=3.
3. Press “ to display the current calibration options as shown in Figure 3-118.
