Setting the voltage rise time (RISE TIME)
The rise time between the start voltage and the test voltage can be set to 0.1 s
through 200 s (at a resolution of 0.1 s for the 0.1 s to 99.9 s range and 1 s for the 100
s to 200 s range).
When the cursor is to the right of RISE, settings can be made using the rotary knob.
1.
To mo
v
e the c
u
rsor to RISE, press the F2 key (RISE TM). (The
keys can also
b
e
u
sed.)
2.
Using the
keys, mo
v
e the c
u
rsor to the target digit.
3.
Using the rotary kno
b
, set the rise time.
The figure (
V
/s) in parentheses represents the voltage increase per second calculated
for reference using the set value.
If the value cannot be displayed in three digits, “---” is displayed instead.
Discharge time (DISCH TIME)
The discharge time, the amount of time after insulation resistance testing is com-
pleted for which the tester forcibly discharges, can be set to a value between 0.5 and
300 s (in 0.1 s steps from 0.5 to 99.9 and in 1 s steps from 100 to 300 s).
If you set the discharge time to 0.0 s, the tester will continue discharging until the
voltage between the output terminals falls below approximately 30
V
. If the voltage
between the output terminals exceeds approximately 30
V
even after the specified
discharge time has passed, the tester will continue discharging until the voltage falls
below that value.
When the cursor is to the right of DISCH, settings can be made using the rotary
knob.
1.
To mo

u
rsor to the right of DISCH, press the F3 key (DISCH).
