AMETEK SLM Series RevC - Manual (Page 30)

Operation Sorensen SLM-Series DC Load
3-2 M540071-01 Rev C
1 Module Label
Shows the load model name and its maximum ratings.
2 NG LED
Lights to indicate "No Go" (fail) when Vmeter, Ameter, or Wattmeter exceeds the upper or
lower limit set. Off, not lit, indicates "Go" (no fail).
3 CC, CR, CV, CP LEDs and MODE Key
• LEDs indicate which mode is in operation:
◦ CC = Constant Current
◦ CR = Constant Resistance
◦ CV = Constant Voltage
◦ CP = Constant Power
• The MODE key switches from one mode to the next.
4 REM LED
Indicates remote operation:
• When lit, the unit is under remote control and cannot be operated through the front
panel keys. (Remote controller releases control by GPIB command).
• When off, the unit is under local control and can be manually operated using the front
panel keys.
5 Upper 5-Character Digital Meter (DM) and Associated LEDs
The DM is for multi-purpose display, depending on selected mode:
• In PRESet OFF mode, displays voltage of DC input terminal or V SENSE BNC input.
• In PRESet ON mode, displays values being programmed for CV, CR, or CP (value for
CC is displayed in lower DM).
• In WATT On mode, displays load Watt meter.
• In LIMIT ON mode:
◦ displays GO/NG upper limit values for voltage, current, and power
◦ displays SENSE to indicate V
SENSE control
◦ displays voltage settings for LOAD ON or for LOAD OFF
Associated LEDs indicate the displayed value's unit:
• V = Value displayed is in Volts
• A = Value displayed is in Amps
• Ω = Value displayed is in Ohms
• W = Value displayed is in Watts
• ms = Value displayed is in milliseconds
• A/ μs (or mA/μs) = Value displayed is in Amps per microsecond (or milliamps per
microsecond)
