The test leads can add 0.1Ω to 0.3Ω of error to resistance
measurement.
For high-resistance measurement(>1MΩ), it is normal
taking several seconds to obtain a stable reading.
In each range, the Meter has an input impedance of 10 KΩ
This loading effect can cause measurement errors in high
impedance circuits. If the circuit impedance is less than or
equal to 10kΩ, the error is negligible (0.1 or less).
When DC voltage measurement has been completed,
disconnect the connection between the testing leads and
the circuit under test and remove testing leads from the
input terminals.
Do not apply more than the rated voltage, as marked
on the Meter, between the termials or between any
terminal and grounding. If the value to be measured is
unknown, use the maximum range and reduce the range
step by step until a satisfactory reading is obtained.
When measurement has been completed, disconnect
test leads from the circuits under test, remove the testing
leads away from the input terminals of the Meter and
turn the Meter power off.
The rotary switch should be placed in the right
position and no any changeover of range shall be made
during measurement to prevent damage of the Meter.
To avoid electric shock, do not carry out the
measurement when the Meter,s back case and battery
compartment are not closed.
Do not input higher than 600V between the Meter,s
terminals and the grounding to avoid electric shock
and damages to the Meter.
When the Meter working at an effective voltage over
60V in DC or 30V rms in AC, special care should be
taken for there is danger of electric shock.
Use the proper terminals, function, and range for
your measurements.
Do not use or store the Meter in an environment of
high temperature, humidity, explosive, inflammable and
strong magnetic field. The performance of the Meter
may deleriorate after dampened.
When using the test leads, keep your fingers behind
the finger guards.
Disconnect circuit power and discharge all high
behind the finger guards.
Disconnect circuit power and discharge all high
-voltage capacitors before testing resistance, continuity
and diode.
Replace the battery as soon as the battery indicator
appears. Whith a low battery, the Meter might produce
false readings that can lead to electric shock and
personal injury
When servicing the Meter, use the replacement parts
with the same model or identical electrical specifications.
To avoid any damage to the meter or any accident,
do not alter the internal circuit of the Meter randomly.
Soft cloth and mild detergent should be used to clean
the surface of the Meter when servicing. No abrasive
and solvent should be used to prevent the surface of
the Meter from corrosion, damage and accident.
The Meter is suitable for indoor use.
Turn the Meter off when it is not in use and take out
the battery when not using for a long time.
Constantly check the battery as it may leak when it
has been used for some time, replace the battery as
soon as leaking appears. A leaking battery will damage
the Meter.
Probe assemblies to be used for MAINS measurements
shall be RATED as appropriate for MEASUREMENT
CATEGORY III according to IEC 61010-031 and shall have
a voltage RATING of at least the voltage of the circuit to
be measured.
