PROCEDURE
A4R(C)403 OVP DELAY ADJ Adjusts delay time of Overvoltage Protection. PAR. 4.4
A4R432 C. MON FS Calibrates full scale for the current monitor signal. PAR. 4.6.4
A4R430 C. MON ZERO Calibrates zero for the current monitor signal. PAR. 4.5.3
A4R415 OVP ADJ Adjusts Overvoltage Protection level. PAR.4.4
A1R14 EOUT ZERO Calibrates zero for output voltage. PAR. 4.5.2
A1R4 EOUT FS LOC Calibrates full scale for output voltage controlled from
front panel VOLTAGE potentiometer (local). PAR. 4.5.2.1
A1S1 EOUT LOC – EOUT REM Enables output voltage control from either front panel
(local) or remote location using a variable resistance. PAR. 4.5.5
A1R16 EO LAG COMP Adjusts for stability (eliminates oscillation) in voltage
mode. PAR. 4.3
A1R33 EO FS REM Calibrates full scale output voltage using remote resistive
control. PAR. 4.5.2.2
A1R19 IOUT FS "A" Calibrates full scale for output current limit "A." PAR. 4.6.5
