MeasRang
: Select the appropriate current range for
IR
, calculate the current value according to the
test voltage and the expected insulation impedance of the DUT, ie I = U/R, and then select the
appropriate current range accordingly. Relationship between the current range and resistance
measurement range is shown in table
4-6.

4.3.4 Pause Mode
Figure 4-15 Pause Mode Setup
Message: message prompt string, you can enter English letters, Arabic numerals, and [.] and [-] in
the status bar up to a maximum of 20 characters, after which ST will appear in the 21th position.
Press keys from 2 to 9 repeatedly to cycle through the letters depicted on them. You can also use the
softkeys to add characters. Use [BAS] to erase the last letter, finish with [ENTER], cancel with
[ESC] or a cursor key.
PausTime: the action mode of setting the pause mode
a)
When set to 0, to continue testing, the pause mode would be ended as either the [START] key
on the front panel is pressed, or the external [START] signal is retriggered.
b) When set to 0.3~999.0s, if the set time finishes, the pause mode ends.
