LOCATION AND DESCRIPTION OF
OPERATING CONTROLS
In order to use the full capabilities of the 1332A, it is highly
recomended that the user become familiar with the
controls associated with this instrument. (See Figure 1)
Figure 1. Location of operating controls.
1-Power ON/OFF switch. 7-Current Fine Control Clockwise
rotation increases variable output
current in CC mode.
2-Supply LED Display. 8-CV LED
Display Voltage 0 to 32VDC Constant Voltage mode Indication
3-Supply LED Display. 9-CC LED
Displays current 0 to 5AMP. Constant Current Mode Indication
4-Variable coarse voltage control. 10-Output terminals
Clockwise rotation increases Red terminal is output (+)ve.
variable o/p voltage in CV mode. Black terminal is output (-)ve.
