4. CONSIDERATION OF MEASUREMENT
(1) This C METER is intended for measuring the capacitance value of
a capacitor. It is not intended for determining the “Q” factor for
above reactive components. Misleading readings may be obtained
if the measurement of capacitance of a resistor is attempted.
(2) When measuring components within circuit that circuit must be
switched off and de-energized before connecting the test leads.
(3) Do not damage (black & red) test leads, if any worn please change
(4) Instruments used in dusty environments should be stripped and
cleaned periodically.
(5) Do not leave the instrument exposed to direct heat from the sun for
long periods.
(6) Before removing the battery and fuse compartment cover, ensure
that the instrument is disconnected with any circuit and the power
switch is in the off position.
(7) For all measurements, should connect BLACK test lead into “-”
terminal and RED test lead into “+” terminal.
5. CAPACITANCE(C) MEASURING PROCEDURE
(1)Select the range selector for the maximum expected capacitance.
(2)The power will on when the selector switch away from OFF
position.
(3)Check "0" indication: If test range is 200pF, 2nF, 20nF, should
check "0" indication before test.
(4)Observe polarity when connecting polarized capacitors.
(5)Full discharge any capacitors.
(6)Connect the alligator clips to the capacitors leads.
(7)Read the display. The value is direct reading in the electrical unit
(pF, nF, uF) indicated at the selected range switch. If display show
“1”, It indicate on Out-of-Range measurement. If the display
indicates one or more leading zeros, shift to the next lower range
scale to improve the resolution of the measurement.

6. MAINTENANCE
1) 9-Volt battery replacement
a. Ensure the instrument is not connected to any external circuit. Set
the selector switch to OFF position and remove the test leads from
terminals.
b. Remove the screw on the bottom case and lift the bottom case.
c. Remove the spent battery and replace it with a battery of the same
type.
