Programmable DC Power Supply (with Solar Array Simulation) 62000H Series
Operating & Programming Manual
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.
3.3.7.7.3 Calibration Procedure
1. Go to the CALIBRATION page as shown in Figure 3-136.
2. In the CALIBRATION page, press “ ” or turn the “Rotary” ( ) knob to set
CHOICE=2.
3. Press “ ” to display the current calibration options as shown in Figure 3-142.

4. Verify all loads have been removed from the output terminal and press “ ” to
confirm.
5. Press “ ” to do the first low current range point calibration. The system will output a
fixed voltage and then set the Electronic Load to draw 1.0A current. The cursor will stop
at position [1] as shown in Figure 3-143. Enter the current read by the ULTRASTAB
SATURN (DVM) to position [1] and press “ ” to confirm it.

6. Turn off the Electronic Load and reconnect the DC Power Supply to a current shunt
whose rating is closest to but still covers 20A. For the Prodigit 7550, use the 20A shunt
directly.
7. Press “ ” to perform the 6.7A calibration. The cursor will stop at position [2] as
shown in Figure 3-144. Set the Electronic Load to draw 6.700A current. Enter the current
read by the ULTRASTAB SATURN (DVM) and press “ ” to confirm. Using the
calibration values obtained, the system will calculate the calibration factor for the low
current range.
