1. Introduction

It is a handheld digital Clamp Mater. It could be used in family, school, lab and other circumstance, where high current 

measurement is required. The series consists of the following models
All models measure:
•  AC/DC Voltage
•  AC Current
•  Resistance
•  Capacitance
•  Frequency
•  Continuity
•  Diode
•  Temp

The Digital AC Current fork meter features:

•  Auto Power OFF
•  Data Hold
•  Backlight LCD display

2. Safety

2-1. International Safely Symbols

 This symbol, adjacent to a terminal, indicates that, under normal use, hazardous voltages may be present
 Double insulation

2-2. Safety Notes

•  Do not exceed the maximum allowable input range of any function.
•  Do not apply voltage to meter when resistance function is selected.
•  Set the function switch OFF when the meter is not in use.
•  Remove the battery if meter is to be stored for longer than 60 days.

2-3. Warnings

•  Sat function switch to the appropriate position before measuring.
•  When measuring voltS do not switch to current/resistance modes.
•  Do not measure current on a circuit whose voltage exceeds 600V.
•  When changing ranges always disconnect the test leads from the circuit under test.
•  Replace the batteries as soon as the low battery indicator   appears

2-4. Cautions

•   Improper use of this meter can cause damage, shock, injury or death. Read and understand this user manual before 

operating the meter.

•  Always remove the test leads before replacing the battery.
•   Inspect the condition of the test leads and the meter Itself for any damage before operating the meter. Repair or replace 

any damage before use.

•   Use great care when making measurements if the voltages are greater than 25V AC rms or 35V DC. These voltages are 

considered a shock hazard.

•   Always discharge capacitors and remove power from the device under test before performing Diode, Resistance or Continuity 

tests.
