SAFETY INFORMATION: (Read First Before Operation)
Please follow the following instructions carefully for safe operation.
■NEVER use the clamp meter for Voltages higher than 600V.
■DO NOT hold __
the clamp meter beyond its tactile barrier.
■DO NOT use the clamp meter and accessories if they look
damaged.
■USE CAUTION when working with high voltages.
■USE CAUTION when measuring the voltages higher than
30VAC rms or 60VDC. These voltages pose a shock hazard.
■USE EXTREME CAUTION when working around bare
conductors or bus bars.
■ALWAYS use the clamp meter as the instructions in the manual.
WARNING: If the clamp meter is used in a manner
not specified by the manufacturer, the protection
provided by the clamp meter may be impaired.

4. On/Off Sw�ch
This is used to tum the power on or off.
5. Data Hold Button
Once this button is pushed, reading shall be held on the LCD. Press again to release
it. This button is not available in continuity function.
6. Max/Min Hold Button
This button is used to enable the maximum or minimum value to be displayed and

7. Zero/Relative Button
Once this button is pressed, the current reading shall be set to zero and be used as
a zero reference value for all other subsequent measurement. The function is also

MAX/MIN button is pressed. This button is not available in continuity or Hz function.
8.LCD
This is a 3 3/4 digit Liquid Crystal Display with maximum indication of 3999.
Function symbols, units, bargraph, sign, decimal points, low battery symbols,
max/min symbols, and zero symbol are included.
9. Low Battery Symbol
When this symbol appears, it means the battery voltage drops below the minimum
required voltage. Refer to Section V for battery replacement.
10. Zero/Relative Symbol
When this symbol appears, it means a reference value has been subtracted from
the actual reading. The reading shown is a offseted value. Press and hold the zero
button for 2 seconds to disable this function.
11. Data Hold Symbol
Once the hold button is pressed, this symbol appears on LCD.
12. Bargraph
Bargraph has forty segments. It displays segments proportional to the actual
reading. Each segment represent one count.
13. Max/Min Hold Symbol
Once the max/min button is pressed, either MAX or MIN shall be displayed on LCD.
14. Continuity Symbol
If ohm and continuity function is selected, this symbol shall appears on LCD.
15. Units Symbols
Once a function is selected, corresponding unit 0/, n, A, or Hz) shall be displayed
on LCD.
16. VnHz Input Terminal
This terminal is used as input for voltage, ohm/continuity, or frequency
measurements.
17. COM Terminal
This terminal is used as common reference input.
18. Hand Strap
Put your hand through the hole of hand strap to avoid accidental drop of the clamp
4
meter.

3. Operation Instructions
3.1. DC/AC Current Measurements
WARNING: Make sure that all the test leads are disconnected from the meter's
terminals for current measurement.
3.1.1. DC Current
a. Set the rotary switch at 40A DC or 200A DC.
b. Push the zero button to adjust the reading to zero.
c. Press the trigger to open the jaw and fully enclose the conductor to be
measured. No air gap is allowed between the two half
jaws.
d. Read the measured value from the LCD display.
3.1.2. AC Current
a. Set the rotary switch at 40A AC or 200A AC
b. Press the trigger to open the jaw and fully enclose the conductor to be
measured. No air gap is allowed between the two half jaws.
6
c. Read the measured value from the LCD display.
3.2. DC/AC Voltage Measurements
WARNING:
Maximum input for DC V is 600, and for AC V is 600. Do not
attempt to take any voltage measurement that exceeds the limits. Exceeding
the limits could cause elecbical shock and damage to the clamp meter.
3.2.1. DC Voltage
a. Set the rotary switch at V DC.
b. Insert the test leads into the input jack.
c. Connect the test prods of the test leads in PARALLEL to the circuit to be
measured.
d. Read the measured value from the LCD display.
3.2.2. AC Voltage
a. Set the rotary switch at V AC
b. Insert the test leads into the input jack.
c. Connect the test prods of the test leads in PARALLEL to the circuit to be
measured.
d. Read the measured value from the LCD display.

G: Before taking any in-circuit resistance measurement, remove power
·rcuit being tested and discharge all the capacitors.
3.3. Resistance and Continuity Measurement
3.3.1. Set the rotary switch at n
3.3.2. Insert the test leads into the input jack.
3.3.3. Connect the test prods of the test leads to the two ends of
the resistor or
circuit to be measured.
3.3.4. Read the measured value from the LCD display.
3.3.5. If the resistance is lower than 40 n, a beeping sound shall be heard.
3.4. Frequency {Hz) Measurement
3.4.1. Set the rotary switch at Hz.
3.4.2. Insert the test leads into the input jack.
3.4.3. Connect the test prods of the test leads in PARALLEL to the signal or
circuit to be measured.
3.4.4. Read the measured value from the LCD display.
3.5. Relative Reading Measurements
The zero button also can be used to make a relative measurement. Once the
button is pushed, the current reading is set to zero and a zero symbol shall be
displayed on LCD. All the subsequent measurement shall be displayed as a
relative value with respect to the value being zeroed. Press the zero button again
to return to normal mode. But this function is disabled if MAX/MIN function is
enabled. Please watch for symbol displayed on LCD.
NOTE:
1. The ZERO button is disabled if ohm and continuity or Hz function is selected.
2. LCD displays relative numerical value without bargraph.
3.6. Holding the LCD Reading
Press the HOLD button, then the reading shall be hold and kept on LCD.
II NOTE: The HOLD button is disabled if ohm and continuity function is selected.
II
3.7. Finding the MAX/MIN Value
Press the MAX/MIN button to enable the maximum and minimum values to be
8
recorded and updated during measurement. Push the button once, the
maximum value shall be displayed and updated. The LCD display toggles
between the MAX and MIN values. To exit MAX/MIN function, press and hold
the MAX/MIN button for more than 2 seconds. If MAX/MIN button is pressed, the
ZERO function will be disabled and the ZERO symbol will disappear from LCD.
NOTE: The MAX/MIN button is disabled if ohm and continuity or Hz function is
selected.
