µ
A rms /100 uA p-p, for 115V a-c input voltage
(chassis to EARTH-GND)
Enable/Disable Output Power
Local Front panel Keypad: disable both digital and analog programming sig-
nals.
Remote - IEEE 488 (GPIB) port
- RS 232 port
- Status & Remote On/Off
port
- TTL signal
- NO relay contact
- NC relay contact type.
- Trigger port (shutdown line)
Disables both digital and analog pro-
gramming signals. Shutdown line is for
disable only - removing the signal does
not reenable the output.
Output Display
Two decimal places are used for voltage settings and three decimal
places for current settings (except that only one decimal place is used
for setting voltage on Models BHK 1000-40MG and BHK 2000-20MG).
