AC Clamp Meter User Manual

I. Overview

The UT201+, UT202+, and UT202A+ are true RMS AC clamp meters.

They are designed accord ing to EN61010-1 and CAT II 600V/

CAT III 300V safety standards. These meters come with full-featured

protection which ensures users a safe and reliable measurement

experience. Aside from all the normal features of AC clamp meter,

these meters also include high voltage frequency measurement, fast

capacitance measurement, audio visual NCV detection, and plenty

of additional safety features. UT202A+ also comes with live/neutral

wire detection.

response: 50Hz~100Hz; current frequency measurement function

• Large capacitance (4mF) and temperature measurement (UT202+ only)

• Very large capacitance (60mF), low voltage frequency (10MHz),

and live/neutral wire measurement functions (UT202A+ only)

• Large LCD and fast refresh rate (3 times/s)

• Response time for capacitance measurement: less than 3s for 1mF; ≤

about 6s for 10mF; about 8s for 60mF≤ ≤

IV. Safety Instructions

The meter is designed according to EN61010-1, 61010-2-032/033

and electromagnetic radiation protection EN61326-1 safety standards,

and conforms to CAT II 600V, CAT III 300V, double insulation and

pollution grade II.

Note: In case the meter is not used in acco rdance with the

operating instructions, the protection provided by the meter may be

weakened or lost.

1.Before use, please check if there is any item which is damaged or

behaving abnormally. If any abnormal item (such as bare test lead,

damaged meter casing, broken LCD, etc.) is found, or if the meter

is considered to be malfunctioning, please do not use the meter.

2.Do not use the meter if the rear cover or the battery cover is not

covered up, or it will pose a shock hazard!

3.When using the meter, keep fingers behind the finger guards of the

test leads, and do not touch exposed wires, connectors, unused

inputs, or circuits being measured to prevent electric shock.

4.The function switch should be placed in the correct position before

measurement. It is forbidden to change the position during

measurement to avoid damage to the meter!

5.Do not apply voltage over 600V between any meter terminal and

earth ground to prevent electric shock or damage to the meter.

6. Be cautious when the measured voltage is higher than 60V (DC)

or 30Vrms (AC) to avoid electric shock!

7.Never input voltage or current which exceeds the specified limit. If

the range of the measured value is unknown, the maximum range

should be selected.

8.Before measuring the resistance, diode and continuity online, switch

off the power supply of the circuit, and fully discharge all capacitors

to avoid inaccurate measurement.

VIII. Button Description

1.SELECT Button

In the composite function position, press this button to switch between the

corresponding measurement functions; in the AC/DC/Hz position (UT202+/

UT202A+), short press this button to switch between the AC and DC

functions, and long press (about 2s) this button to enter/exit the Hz

measurement function.

In the NCV/LIVE position (UT202A+ only), short press this button to switch

between the EFHI and EFLo ranges, and long press (about 2s) this button

to enter/exit the LIVE measurement function.

2.HOLD/BACKLIGHT Button

Short press this button to enter/exit the data hold mode, and long press

(about 2s) this button to turn on/o ff the backlight (the backlight will

automatically turn off after 60s).

3.MAX/MIN Button

Short press this button to enter the maximum/minimum measurement mode

and long press this button to exit (only valid for AC/DC voltage, AC current,

resistance and temperature measurement).

4.REL Button (UT202+/UT202A+)

In the capacitance and voltage positions, press this button to store the

current reading as a reference for future readings. When the LCD display

value is reset to zero, the stored reading will be subtracted from the future

readings. Press this button again to exit the relative value mode.

2.AC/DC Voltage and Voltage Frequency Measurement (Picture 3)

1) Insert the red test lead into the “ ” jack, black into

the “ ” jack.COM

2) Turn the function switch to the AC/DC voltage position, and connect

the test leads with the measured load or power supply in parallel.

3.Resistance Measurement (Picture 4)

1) Insert the red test lead into the “ ” jack, black into

the “ ” jack.COM

Resistance

Note:

• If the measured resistor is open or the resistance exceeds the

maximum range, the LCD will display “OL”.

• Before measuring the resistance online, switch off the power supply

of the circuit, and fully discharge all capacitors to avoid inaccurate

measurement.

• If the resistance is not less than 0.5Ω when the test leads are

short-circuited, please check the test leads for looseness or other

abnormalities.

• Do not input voltage higher than 30V to avoid personal injury.

4.Continuity Test (Picture 4)

1) Insert the red test lead into the “ ” jack, black into

the “ ” jack.

2) Turn the function switch to the “ ” position, press the SELECT

button to select continuity measurement, and connect the test leads

with both ends of the measured load in parallel.

3) Measured resistance <10Ω: The circuit is in good conduction status;

the buzzer beeps continuously. Measured resistance >31Ω: The

buzzer makes no sound.

Note:

• Before measuring the continuity online, switch off the power supply

of the circuit, and fully discharge all capacitors.

• Do not input voltage higher than 30V to avoid personal injury.

5. Diode Test (Picture 4)

1) Insert the red test lead into the “ ” jack, black into

the “ ” jack. The polarity of the red test lead is “+” and that COM

the black test lead is “-”.of

2) Turn the function switch to the “ ” position, press the SELECT

button to select diode measurement, and connect the test leads

with the positive and negative poles of the measured diode.

3) 0.08V reading <1.2V: The buzzer makes one beep indicating ≤

the normality of the diode. Reading <0.08V: The buzzer beeps

continuously indicating the damage of the diode. For the silicon

PN junction, the normal value is generally about 500~800 mV.

9.When the “ ” symbol appears on the LCD, please replace the batteries

in time to ensure measurement accuracy. If the meter is not in use for a

long time, please remove the batteries.

Note:

• The current measurement must be taken within 0°C~40°C. Do not

suddenly release the trigger, as the impact will change the reading

for a short time.

• To ensure measurement accuracy, center the conductor in the jaws.

Otherwise, ±1.0% additional error in reading will be produced.

• When the measured current is 400A (UT201+/UT202+)/ 600A ≥ ≥

(UT202A+), the meter will automatically sound an alarm and the

high voltage alarm prompt “ ” will automatically flash.

• If the LCD displays “OL”, it indicates that the current is over range

and there is a danger of damage to the meter.

Note:

• If the diode is open or its polarity is reversed, the LCD will display

“OL”.

• Before measuring the diode online, switch off the power supply of

the circuit, and fully discharge all capacitors.

• Do not input voltage higher than 30V to avoid personal injury.

Note:

• Do not input voltage above 600V. Although it is possible to measure

higher voltage, it may damage the meter.

• Be cautious to avoid electric shock when measuring high voltage.

• When the measured voltage is 30V (AC) or 60V (DC), the LCD ≥ ≥

will display the high voltage alarm prompt “
