1.3 Names and Functions of Parts
12
Test setting conditions and current status of the instrument are shown in the
panel on front of the instrument.
1.3.2 Display
Test type
“AC” lights up during withstanding testing.
“DC” lights up during insulation-resistance testing.
Test-voltage value
During testing and READY:
Monitors and indicates the voltage of the output ter-
minal.
During voltage setting:
Indicates the each item set. (output voltage, Con-
tact Check upper (lower)-limit voltage)
Reverse current cannot be detected because monitor
shows voltage and residual voltage.
Upper-limit value icon Lights up when indicating the upper-limit test value.
Lower-limit value icon Lights up when indicating the lower-limit test value.
Upper-limit test value
Lower-limit test value
Indicates the upper-limit test value when the upper-
limit value icon lights up and indicates the lower-limit
test value when the lower-limit value icon lights up.
Also indicates the Contact Check upper-limit voltage
when [Hi] is shown in Test Frequency and Initial
Ramp-up Voltage, and indicates the Contact Check
lower-limit voltage with [Lo].
Test time
Ramp-up time
Ramp-down time
Delay time
Indicates testing time.
Indicates the ramp-up time when [UP] is shown in Test
Frequency and Initial Ramp-up Voltage, and indicates
the ramp-down time together with [dn].
Indicates the delay time together with [dL] during insu-
lation-resistance testing.
Test-frequency
Initial voltage for
ramp-up
Indicates Test Frequency (50 Hz/60 Hz) when [Hz] is
shown. Indicates the Initial Voltage (proportion to Test-
ing Voltage) when Ramp-up Timer is being used
within the range of 0 to 1.0.

Test type
Indicates the current condition of the instrument
: The instrument is ready for starting a test
: The instrument is in the TEST state.
: The tested object passed the test.
: The tested object failed to pass the test.
