STRUCTURE
1. Jaws
Used to clamp the conductor for ac current measurements.
2. ʺFUNC./HOLDʺ Button
1. Used to enter/exit Data Hold mode in voltage, current or resistance
measurement functions.
2. Used to switch the meter between the diode and continuity test functions
when the rotary switch is in the "
3. Display
3 / digit LCD, with a max. reading of 1999.

4. "COM" Terminal
Plug-in oonnector for the black test lead.
5. "VΩ ʺ Terminal
Plug-in connector for the red test lead.
6. Function/Range Swltch
Used to select desired function or range as well as to tum on or off the meter.
7. Trigger
Used to open and close the jaws.
8. Tactile Barrier
Used to prevent fi
nger from touching the conductor under test. Do not hold the meter
anywhere beyond the tactile barrier.
Instruction for the Built-in Buzzer:
When you press the ʺFUNC./HOLDʺ button, the buzzer will sound a beep if the press is effective.
Before the meter tums off automatically, it will sound 5 short beeps, 1 minute later it will sound a long beep and then tum off
automatically.
Note: When the function/range switch in the "2/20A~" position, the buzzer is disabled.
OPERATING INSTRUCTION
Data Hold Mode
Press the ʺFUNC./HOLDʺ button to hold the present reading on the display. "D.Hʺ appears on the display as an indicator.
To exit Data Hold mode, just press the button again. ʺD.Hʺ disappears.
Note:
Data Hold mode is available only in voltage, current and resistance functions.
Measuring DC Voltage
1. Connect the black test lead to the ʺCOMʺ terminal and the red test lead to the ʺVΩ
2. Set the rotary switch to
3. Connect the test leads across the source or circuit to be measured.
4. Read the reading on the display. The polarity of the red test lead connectlon will be indicated as well.
Note: To avoid electric shock to you or damages to the meter, do not apply a voltage higher than 600V between terminals.
Measuring AC Voltage
1. Connect the black test lead to the ʺCOMʺ terminal and the red test lead to the ʺVΩ
2. Set the rotary switch to
3. Connect the test leads across the source or circuit to be measured.
4. Read the reading on the display.
Note:
To avoid electric shock to you or damages to the meter, do not apply a voltage higher than 600V between terminals.
Measuring AC Current
1. Set the rotary switch to the desired AC current range position.
2. Press the trigger and clamp the jaws around the conductor to be tested. Make sure that the jaws are perfectly closed.
Note:
a. Each time only one conductor should be clamped.
b. The conductor should be in the center of the jaws in order to get an accurate reading.
c. Don't touch any conductor with hand or skln.
3. Read the reading on the display.
