Descriptions of Panel
4-21
FALL TIME : Sets the fall time of the voltage to 0. (0=OFF).
CHNL (H-L) : The setting is the same as AC CHANNEL.
Insulation Resistance Test Mode (IR)
VOLTAGE
: Sets the insulation resistance test voltage.
LOW LIMIT
: Sets the insulation resistance low limit value.
HIGH LIMIT : Sets the insulation resistance high limit value. The value is ≥ insulation
resistance low limit value or OFF.
TEST TIME
: Sets the test duration time. (0=CONTINUOUS)
RAMP TIME : Sets the ramp time. (0=OFF)
FALL TIME : Sets the fall time of the voltage to 0 (0=OFF)
RANGE : Select the test file for the insulation resistance test (AUTO= Auto Range). The
relationship between the current file and resistance measurement range is
shown in the table below:

Note: Use the test voltage and insulation resistance of the DUT to calculate the value of current to
choose the suitable current file.
CHNL (H-L)
: The setting is the same as AC/DC CHANNEL.
Or scanning test selection point (use with optional device, for example 6000-03).
Leakage current test mode (LC) ---- Option
Pause test mode (PA)
MESSAGE: Message string. The string may be alphabetic, numeric, or symbolic [-] (max. 13
characters.)
UNDER TEST: Set to ON or OFF.
(1) When set to ON: the UNDER TEST relay terminal on the rear panel is closed.
(2) When set to OFF: the UNDER TEST relay terminal on the rear panel is open.
TEST TIME: Set the action method of pause mode.
(1) When set to CONTINUE, pause mode will be ended till press [START] on panel or
re-trigger START signal on rear panel.
