responding symbol will appear on the LCD screen. In automatic resistance measure-
ment mode, you could select manual measurement by pressing “Range”.
Caution:
a) When measuring the capacity, all the
powers within the tested circuits must
be disconnected and the capacitance
shall be sufficiently discharged.
b) When measuring the resistance, any
occurrence of voltage may Lead to
inaccurate readings, and if the 250V
protection voltage is exceeded, it may
damage the meter or threaten the safety of the user.
c) When the range of 600Ω is in use, first sort-circuit the meter pens and measure the
resistance of the lead wires and then deduct it in the actual measurement.
