Press and hold the button for 2 seconds to enter directly into the "MAX"
mode, press repeatedly to switch between "MAX" and "MIN" mode,
Press and hold for 2 seconds to exit "MAX"/ "MIN" mode.
LOCK :
In the insulation resistance testing function, press the "LOCK"
button and then push down the "TEST" key to apply the high-
voltage and enter the insulation resistance testing mode. Press
the "TEST" button once more to shut off the high-voltage and
exit from the insulation resistance testing status.
TEST :
In the insulation resistance testing function, press and hold the
"TEST" button to apply the high-voltage and enter into the
insulation resistance testing mode; release the "TEST" button to
cutoff the high-voltage and exit from the insulation resistance
testing mode.
ZERO/LIGHT :
Press the "ZERO/LIGHT" button and the current values in
the primary display will be set to zero,(mainly used for
400Ω, the low resistance testing), press it again to switch
off zeroing, press and hold the button for 2 seconds to
switch the LCD backlight on. After 15 seconds, the backlight
will shut off automatically; pressing the button for 2 seconds
within 15s will also switch off the backlight.
