AMETEK SLH Series RevC - Manual (Page 33)

Sorensen SLH-Series DC High Power Electronic Load Operation
• In PRESet OFF mode:
◦ displays actual load current when SHORT status is OFF
◦ displays short circuit current when SHORT status is ON
• In PRESet ON mode, the lower DM displays:
◦ value being programmed for CC
◦ values being programmed for T
HIGH /T LOW when in Dynamic mode
◦ values being programmed for RISE/FALL slew rates when in Dynamic mode
• In LIMIT ON mode:
◦ displays oVP (over voltage), oCP (over current), oPP (over power), or
oTP (over temperature) when in protection mode
◦ displays GO/NG low limit values for voltage, current, and power
◦ displays Auto or On setting for V
SENSE control
◦ displays either Ld-on or Ld-off to indicate whether Load voltage setting mode is
On or 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)
7 PRES Key and ON/WATT LED
• PRES key sequentially selects Preset ON, Watt ON and Preset OFF
• LEDs indicate which is selected at any given time:
◦ Preset On = LED is lit amber
◦ Watt On = LED is lit green
◦ Preset Off = LED is not lit
8 LOAD Key and ON/OFF LED
• LOAD key toggles ON/OFF the DC load input function. (Does not affect the
programmed settings).
• LED indicates the status of the Load function:
◦ LED is lit to indicate the Load function is ON and ready to sink current from the
DC input.
◦ LED is not lit, indicating the Load function is OFF.
