Overview
This Operating Manual covers information on safety and
cautions. Please read the relevant information carefully
and observe all the
Warnings
and
Notes
strictly.
Warning
To avoid electric shock or personal injury, read the
“Safety Information”carefully before using the Meter.
G9204 are AC clamp multimeters(hereafter referred
to as "the Meter") with remarkable features: versatile
functions, stable operation, low power consumption and
ergonomic structural design. They can measure AC/DC
voltage, AC current, resistance,diode, continuity, frequency
and temperature,etc.
Except where noted, the descriptions and instructions in
this Operating Manual apply to both the
G9204.

Safety Information
This Meter complies with the standard IEC61010: Pollution
Degree 2, Overvoltage Category (CAT. II 600V / CAT III
300V) and Double Insulation.
CAT II: Local level, appliance, PORTABLE EQUIPMENT
etc., with smaller transient voltage overvoltages than CAT. III
CAT. III: Distribution level, fixed installation, with smaller
transient overvoltages than CAT. IV.
Under the influence of Radiated, Radio-Frequency Electro
-magnetic Field phenomenon,the captioned model may
malfunction and can self-recover after the test.
Use the Meter only as specified in this operating manual,
otherwise the protection provided by the Meter may be
impaired.
In this manual, a
Warning
identifies conditions and acti
-ons that pose hazards to the user, or may damage the
Meter or the equipment under test.
A
Note
identifies the information that user should pay
attention to.
To avoid possible electric shock or personal injury,
and to avoid possible damageto the Meter or to the
equipment under test, adhere to the following rules:
Check for the lever is in good condition when
measuring AC current.
Must center the wire (conductor) within the trans
-former jaw.
Before using the Meter inspect the case. Do not
use the Meter if it is damaged or the case (or part
of the case) is removed. Look for cracks or missing
plastic. Pay attention to the insulation around the
connectors.
Inspect the test leads for damaged insulation or
exposed metal. Check the test leads for continuity.
Replace damaged test leads with identical model
number or electrical specifications before using
the Meter.
Do not apply more than the rated voltage, as marked
on the Meter, between the terminals or between
any terminal and grounding.
The rotary switch should be placed in the right
When the Meter is working at an effective voltage
over 60V in DC or 42V rms in AC, special care
should be taken for there is danger of electric shock.
Warning
position and no any changeover of range shall be
made when measurement is conducted to prevent
damage of the Meter.
Use the proper terminals, function, and range for
your measurements.
When using the test leads, keep your fingers behind
the finger guards.
Disconnect circuit power and discharge all high-
voltage capacitors before testing.
To avoid harm to you or damage to the Meter from
electric shock, please do not attempt to apply higher
than 600V between the terminals and grounding.
Replace the battery as soon as the battery indicator
appears. With a low battery, the Meter might
produce false readings that can lead to electric
shock and personal injury.
When servicing the Meter, use only the replacement
parts with the same model or identical electrical
specifications.
The internal circuit of the Meter shall not be altered
at will to avoid damage of the Meter and any accident.
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.
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 using for some time,replace the battery
as soon as leaking appears. A leaking battery will
damage the Meter.
Do not use or store the Meter in an environment
of high temperat ure, humidity,explosive, inflamm
-able and strong magnetic field. The performance
of the Meter may deteriorate after dampened

A. Measuring AC Current
(See Figure 3)
Warning
The measurement value obtained is wrong if testing
two or more current conductors at the same time.
Make sure the Sleep Mode is not on if you found there
is no display on the LCD after turning on the Meter.
Make sure the Low Battery Display is not on;
otherwise false readings may be provided.
Pay extra attention to the symbol which is located
besides the input terminals of the Meter before carrying
out measeurement.
Make sure you are in the proper measurement range
before carrying out measurement.

B. Measuring DC Voltage
(See Figure 4)
Warning
To avoid harm to you or damage to the Meter from
electric shock, please do not attempt to measure
voltages higher than 600V although readings may
be obtained.
To measure DC voltage, connect the Meter as follows:
1. Insert the red test lead into the
V
terminal and the
black test lead into the
COM
2. Set the rotary switch to
DC voltage measurement
mode.
Figure 4
Red
Black
3. Connect the test leads across with the object
being measured.
The measured value shows on the display.
In each range, the Meter has an input impedance of
10M .This loading effect can cause measurement
errors in high impedance circuits. If the circuit imped
-ance is less than or equal to 10k , 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 the testing leads
away from the input terminals of the Meter.
Note
AC Voltage measurement is an auto ranging measure
-ment mode.
Follow the same procedure as the DC Voltage Meas
-urement mode. When you using UT206A to carry
out the measurement, use
SELECT
button to switch
between ACV and DCV.
Note:
C. Measuring AC Voltage
(See Figure 4)
D. Measuring Resistance
(See Figure 5)
Warning
To avoid damages to the Meter or to the devices
under test, disconnect circuit power and discharge
all the high-voltage capacitors before measuring
resistance.
To measure resistance, connect the Meter as follows:
1. Insert the red test lead into
the terminal andthe
black test lead into the
COM
terminal.
2. Set the rotary switch to .
3. Connect the test leads
across with the object
being measured.
The measured value shows
on the display.
Note
The test leads can add 0.1 to 0.3 of error to
resistance measurement.To obtain precision readings
in low-resistance measurement under the range of
400.0 , short-circuit the input terminals beforehand,
using the relative measurement function button
REL
to automatically subtract the value measured
when the testing leads are short-circuited from the
reading.

Figure 5
For high-resistance measurement (>1M ), it is
normal to take several seconds to obtain a stable
reading.
When resistance measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test, and remove the testing leads
away from the input terminals of the Meter.
E. Testing for Diodes and Continuity
(See Figure 6)
To avoid damages to the Meter or to the devices
under test, disconnect circuit power and discharge
all the high-voltage capacitors before testing for
continuity.
Warning
To test for diodes and continuity, connect the Meter as
below:

b. For forward voltage drop
readings on any semicon
-ductor component, place the
red test lead on the component’s anode and place
the black test lead on the component’s cathode.
The measured value shows on the display.
3. For continuity test:
a. Press
SELECT
to switch between Diode and Contin
-uity test.
b. Connect the test lead to the two end of the circuit
under test.
c. The buzzer sounds if the resistance of a circuit under
test is less than 100 .
In a circuit, a good diode should still produce a
