AC Volts or Amps range.
2. When measuring voltage or amperes in
the 50Hz (or 60Hz) power line, press and
hold down the DC/AC button for 2 seconds
to select the THD @ 50/60Hz mode.
3. When this Meter enters into the THD
mode, the digital reading (that is, the True-
RMS value of voltage or amperes being
measured) disappears and the symbol, %
and decimal points are displayed on the
LCD.
4. After about 2 seconds from this moment,
the THD-R (%) will be displayed.
5. To exit this mode, press and hold sown
the DC/AC button for 2 seconds again.
The symbol, %, disappears and the Meter
will return to the AC functions.

4.6 Measuring capacitance

CAUTION: DISCHARGE ALL CAPACITORS
BEFORE ATTEMPTING
MEASUREMENTS. FAILURE TO DO SO CAN
RESULT IN DAMAGE TO THE METER.
• In capacitance, the Meter is always
autoranging.
• In ìF range, the readings are probably
unstable due to environmentally induced
electrical noise and floating capacity of
the test loads. Therefore, directly connect
the object to be measured to the input

• Bar graph does not function in capacitance
Follow these steps to measure capacitance:
1. Insert the test leads into the input
terminals.
2. Set the rotary switch to the "CAP"
position.
3. Touch the probes to the capacitor and
read the display. When measuring polarized
capacitors, connect the positive to the VΩHz
CAP terminal and the negative to the COM
terminal. Capacitor dielectric absorption
can cause measurement errors. If more
discharged is necessary, the Meter displays
