Safety

International Safety Symbols

This symbol, adjacent to another symbol or terminal, indicates the user must refer to the manual for further information.
This symbol, adjacent to a terminal, indicates that, under normal use, hazardous voltages may be present
Double insulation

SAFETY NOTES

Do not exceed the maximum allowable input range of any function.
When the instrument is not in use, press the ON/OFF key to turn off the meter.
Remove the battery if meter is to be stored for longer than 60 days.

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.
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 25VAC rms or 35VDC. These voltages are considered a shock hazard.
Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts. Other means should be used to ensure that the terminals are not “live”.

Operation

AC Current Measurements

NOTE : Ensure that the test leads are disconnected from the meter before making current clamp measurements.

Set the Function switch to the AC Current.
Place the current open jaw around the middle of the test lead.
The clamp meter LCD will display the reading.

AC (True RMS)/DC Voltage Measurements

Insert the black test lead into the negative COM terminal and the red test lead into the positive V Ω CAP terminal.
Automatically change between AC or DC.
Connect the test leads in parallel to the circuit under test.
Read the voltage measurement on the LCD display.

Low Z Voltage Measurements

NOTE : Observe all safety precautions when working on live voltage. Do not connect to circuits that exceed 600V AC/DC when the meter is set to Low Z.
Low Z is used when there is a suspicion of a “ghost” voltage. Ghost voltages are present when non-powered wires are in close proximity to wires powered by AC voltage. Capacitive coupling between wires make it appear that non-powered wires are connected to a real source of voltage.
The Low Z setting places a load on the circuit, which dissipates and greatly reduces ghost voltage.

Set the rotary function switch to the Low Z position.
Momentarily press the MODE button to select AC or DC voltage. The AC or DC symbol will appear on the LCD display.
Insert the black test lead into the COM input jack and the red test lead into the V input jack. If measuring DC voltage, touch the red test lead to the positive side of the circuit and the black test lead to the negative sideof the circuit.
Touch the test leads to the circuit under test.
Read the voltage on the LCD display.

Resistance Measurements

Set the function switch to the V Ω CAP position.
Insert the black test lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive jack.
Press the MODE button to indicate “Ω ” on the display.
Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the part under test so the rest of the circuit will not interfere with the resistance reading.
Read the resistance in the display.

Continuity Measurements

Set the function switch to the V Ω CAP position.
Insert the black lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive jack.
Press the MODE button to indicate“ ” and “Ω” on the display
Touch the test probe tips to the circuit or wire you wish to check.
If the resistance is less than approximately 50 Ω, the audible signal will sound. If the circuit is open, the display will indicate “OL”.

Capacitance Measurements

WARNING : To avoid electric shock, discharge the capacitor under test before measuring.

Set the function switch to the V Ω CAP position.
2. Insert the black lead banana plug into the negative COM jack.

Insert the red test lead banana plug into the positive V Ω CAP jack.
Insert the black lead banana plug into the negative COM jack.
Insert the red test lead banana plug into the positive V Ω CAP jack.
Use the MODE button to select CAP Measurements.
Touch the test probe tips across the part under test.
Read the capacitance value in the display.
The display will indicate the proper decimal point and value.
For very large values of capacitance measurement it can take several minutes before the final reading stabilizes.

Diode Measurements

Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the V Ω CAP positive jack
Turn the function switch to Ω CAP position. Use the MODE button to select the diode function if necessary (diode symbol will appear on the LCD when in Diode test mode).
Touch the test probe tips to the diode or semiconductor junction under test.
Note the meter reading.
Reverse the test lead polarity by reversing the red and black leads. Note this reading.
The diode or junction can be evaluated as follows:
- If one reading displays a value (typically 0.400V to 0.900V) and the other reading displays “OL”, the diode is good.
- If both readings display “OL” the device is open.
- If both readings are very small or “0”, the device is shorted.

Non-Contact Voltage (NCV) Measurements

The NCV function works on any rotary switch position.

Test the detector on a known live circuit before use.
Hold the top of the meter very close to the voltage source as shown.
If voltage is present, the red light will long lighting.

NOTE: Do not touch the top of the meter when using this function.
NOTE: Test on known live circuit before using.

Function Buttons

MODE and Backlight Button

Press MODE and Backlight Button to select OHM/Diode/Continuity/CAP/LoZ AC/DC Voltage.
Press the MODE and Backlight button for over 1 second to turn the button, Knob and Rotary light on.
Press again for over 1second to turn the button, Knob, and Rotary light off.

MAX/MIN Button

Press MAX/MIN Button the maximum and minimum values are measured.
This mode is activated on each measurement except for continuity test, diode test capacitance test and AUTO SENSE Voltage mode.
This mode is disabled keeping pressed MAX/MIN Button or moving the rotary switch.

DATA HOLD and Flashlight Button

To freeze the LCD reading, press the HOLD and Flashlight Button.
While data hold is active, the HOLD icon appears on the LCD.
Press the HOLD and Flashlight Button again to return to normal.
Press the HOLD and Flashlight Button for over 1 second to turn the light on.
Press again for over 1second to turn the light off.

Automatic Power OFF

In order to conserve battery life, the meter will automatically turn off after approximately 15 minutes.
To turn the meter on again, turn the function switch to the OFF position and then to the desired function position.
To press and hold the MODE and Backlight Button to turn the system on, the auto power off function will be cancelled.

Maintenance

WARNING: To avoid electrical shock, disconnect the meter from any circuit, remove the test leads from the input terminals, and turn OFF the meter before opening the case. Do not operate the meter with an open case.

Cleaning and Storage

Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for 60 days or more, remove the battery and store it separately.

Battery Replacement

Remove the Phillips head screw that secures the rear battery door
Open the battery compartment.
Replace the 1.5V x 2 AA batteries.
Secure the battery compartment.
