4-10 BOP-1K 031912NOTE: Accuracy of the 10V d-c reference must be ±0.1mV in order for the calibrated unit tomeet published specifications.32.Connect a +10V ±0.1mV d-c reference to pin 3 (S_IN_PARALLEL) referenced to pin 1(SGND) of the PAR/SER CONTROL IN connector (A2A5J3). Set the BOP to maximum posi-tive output current by sending CAL:PAR MAX. Measure the output current using the DVM.Send CAL:DATA commands as needed (see PAR. 4.3b) until the DVM reading is as speci-fied in Table 4-3 for +FULL SCALE CURRENT.33.Save the calibration levels by sending CAL:SAVE 12/21/2003. The characters at the endare optional and represent the calibration date of the power supply. The date entered in thismanner is reported in the *idn? query.4.4 CALIBRATION USING FRONT PANEL KEYPAD IN LOCAL MODEThe following paragraphs describe the screens and keys used in the calibration process.4.4.1 UNDERSTANDING THE CALIBRATION PROCESSThe following steps describe the calibration screens, and associated keys active during the cali-bration process. Refer to PAR. 4.4.2 for full calibration procedure.1. From the power-up screen, press % to enter the General Setup menu, then highlight Cali-bration and press !.2. Enter the password (see PAR. 3.2.4.4), and press !, The LCD shows main calibrationscreen (Figure 4-3) which includes explanations for the following function keys:• ! - VOLTAGE - Selects the voltage calibration of the BOP.• @ - CURRENT - Starts the calibration for the BOP in current mode.• # - EXTRL CONTROLS - Selects input and output signal calibration used for multipleunits and the external protection.• $ - SAVE - Save New Calibration Setting. The information in the DATE field is savedwith the Calibration.
