6. How to use
Select one of the four recording modes, and start recording.
(1)
Record at regular interval in Continuous recording mode
→ P.12
Record the data at the selected intervals. (Interval: 1sec. 〜 60min)
Best suited for checking Leakage varies with time as recording is
performed at regular interval.
(2)
Detect leakage current in Event recording mode
(LED blinks) → P.15
To check the cause of leakage: current value, time and frequency
when exceeding the set current value can be checked. On each
channel, LED blinks when exceeding set value, and can check time
and current value of the last 10data with the instrument. It is helpful
to check the cause of leakage on site.
(3)
Record the max. value in Max. value recording mode.
→ P.18
Best suited for checking the recording time and number of times
from the occurrence to the end of leakage. Record starts when
exceeding the set current value, and record the max value every
10sec.
When exceeding set current value, record the max. value every
10sec.
As recording the value until it drops to 50% of set value or for
10min, can check when intermittent leakage occurs.

4)
Catch waveform in capture recording mode. → P.22
Record waveforms at sampling frequency approx. 900Hz by using
CH1 only. Best suited for waveform observation. When exceeding
set current value, record the instantaneous value in 200ms (10 to
12 waveforms) including 50ms prior to and subsequent to when
exceeding the set value. (* Waveform cannot be displayed on the
LCD of the instrument. Transfer the data to PC by using PC
software of accessory, and check the graphic display.)
