SENSING TERMINALS of the BOP Power Supply.
2. Turn the BOP Power Supply “ON”, program the BOP Power Supply to ZERO VOLTAGE
AND MAXIMUM CURRENT LIMIT.
• If using SCPI send
VOLT 0;CURR MAX
• If using CIIL send
FNC DCS:CH1 VOLT 0 with CURL .5
3. Locate Eo COMP AMP ZERO control R81 (see Figure 3-1, refer to Table 3-1).
4. Adjust control R81 for zero, ±100 microvolts.
3.5 ADJUSTMENT OF THE FULL SCALE OUTPUT VOLTAGE (R21)
1. Program the BOP Power Supply for PLUS FULL SCALE VOLTAGE.
• If using SCPI send
VOLT MAX;CURR MAX
• If using CIIL send
FNC DCS:CH1 VOLT xx with CURL .5
where
xx
is the maximum rated output voltage of the BOP.
