2-8
4. Left status indicators PLS: Pulse source mode or low-resistance measurement
pulse source mode
SWP: Sweep source mode
NOTE: PLS+SWP means pulse sweep, and DC+SW means DC
sweep.
DC: DC source mode.
AC: (Not in use)
HOLD: The trigger mode is set to HOLD.
FMSL: Displays the measurement integration time by using the
indicators in combination.
AUTO: The auto range is set to ON.
4W: The output sensing is set to 4-wire connection.
2W: The output sensing is set to 2-wire connection.
MATH: Scaling calculation is ON.
: Goes ON for every measurement sampling.
: Indicates the sweep operation status.
Rotates during sweep.
Stops rotation at hold.
Goes OFF when sweep stops.
AZ: The measurement auto zero function is ON.
NULL: NULL calculation is ON.
ST: The measurement data memory is ON.
: Buzzer setting is ON.
5. Auxiliary indicator for menu Blinks if a lower hierarchy exists ( key enabled) at parameter
setting on the menu screen.
6. FIT indicator The source range is set to FIT.
7. 4 A indicator The current source or current limiter range is set to 4 A.
8. Output response indicator FAST: The output response is set to Fast.
SLOW: The output response is set to Slow.
9. HL/LL indicator HL: The high limit status is detected.
LL: The low limit status is detected.
10. TpALM indicator The measurement period becomes longer than the setting Tp. The
following factors are possible:
• The source range is changed.
• Measurement auto range
• Auto zero
• The measurement time is longer than Tp.
