on).
MANUAL: The front panel TRIG key must be pressed to trigger the
instrument to take readings.
FINITE: The unit will cycle through measurement cycles for the
programmed trigger count (1 to 99999).
INFINITE: The unit will cycle through measurement cycles indefinitely until
halted.
Manual triggering (TRIG key)
Infinite trigger count (cycle indefinitely through measurement cycles)
Interval (time between measurements): 1s
Delay (time from trigger to measurement): 2s
Press CONFIG then TRIG.
Select TRIGGER-IN, then press ENTER or the Rotary Knob. Select
MANUAL, then press ENTER or the Rotary Knob.
Choose COUNT, then select INFINITE, and press ENTER or the knob.
Select INTERVAL, set the interval to 1s, then press ENTER or the knob.
Choose DELAY, set the delay to 2s, then press ENTER.
Press EXIT to return to normal display.

before the first measurement. The unit will cycle through measurements
indefinitely with a 1s interval between measurements.
Turn the OUTPUT off to stop taking readings.
