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
Do not apply voltage to meter when resistance function is selected.
Set the function switch OFF when the meter is not in use.

WARNINGS

Set 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 240V.
When changing ranges using the selector switch always disconnect the test leads from the circuit under test.
Do not exceed the maximum rated input limits

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 25VAC rms or 35VDC. These voltages are considered a shock hazard.
Remove the battery if the meter is to be stored for long periods.
Always discharge capacitors and remove power from the device under test before performing Diode, Resistance or Continuity tests.

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”.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

Operation

NOTICES: Read and understand all warning and precaution statements listed in the safety section of this operation manual prior to using this meter. Set the function select switch to the OFF position when the meter is not in use.

AC Current Measurements

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

Set the Function switch to the 1000A or400A or 40A range. If the range of the measured is not known, select the higher range first then move to the lower range if necessary.
Press the trigger to open jaw. Fully enclose one conductor to be measured.
The clamp meter LCD will display the reading.

DC/AC Voltage Measurements

Insert the black test lead into the negative COM terminal and the red test lead into the positive V terminal.
Set the function switch to the V position.
Select AC or DC with the MODE button.
Connect the test leads in parallel to the circuit under test.
Read the voltage measurement on the LCD display.

Resistance and Continuity Measurements

Insert the black test lead into the negative COM terminal and the red test lead into the positive terminal.
Set the function switch to the •))) Ω position.
Use the multifunction MODE button to select resistance.
Touch the test probe tips across the circuit or component under test. It is best to disconnect one side of the device under test so the rest of the circuit will not interfere with the resistance reading.
For Resistance tests, read the resistance on the LCD display.
For Continuity tests, if the resistance is < 100Ω, a tone will sound.

Diode Measurements

Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive diode jack.
Turn the rotary switch to the position.
Press the MODE button until “ “ appears in the display.
Touch the test probes to the diode under test. Forward voltage will indicate 0.4V to 0.7V.
Reverse voltage will indicate “OL”. Shorted devices will indicate near 0mV and an open device will indicate “OL” in both polarities.
**Forward test

Reverse test

Capacitance Measurements

WARNING : To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any capacitance measurements.
Remove the batteries and unplug the line cords.

Set the rotary function switch to the cap position.
Insert the black test lead banana plug into the negative (COM) jack.
Insert the red test lead banana plug into the positive (V) jack.
Touch the test leads to the capacitor to be tested.
Read the capacitance value in the display

Frequency or % duty cycle measurements

Set the rotary function switch to the “Hz/%” position.
Insert the black lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack.
Select Hz or % duty with the Hz/% button.
Touch the test probe tips to the circuit under test.
Read the frequency on the display.

Temperature Measurements

WARNING: To avoid electric shock, disconnect both test probes from any source of voltage before making a temperature measurement.

Set the function switch to TEMP.
Insert the Temperature Probe into the negative (COM) and the V jacks, making sure to observe the correct polarity.
Select ° C or ° F with the MODE button.
Touch the Temperature Probe head to the part whose temperature you wish to measure. Keep the probe touching the part under test until the reading stabilizes ( about 30 seconds).
Read the temperature in the display. The digital reading will indicate the proper decimal point and value.
WARNING: To avoid electric shock, be sure the thermocouple has been removed before changing to another measurement function

Data Hold and Backlight
To freeze the LCD meter reading, press the data hold button. The data hold button is located on the left side of the meter (top button). While data hold is active, the HOLD display icon appears on the LCD. Press the data hold button again to return to normal operation.
Note: The HOLD feature will activate when the Backlight is turned on. Press the HOLD key again to exit Hold.
The backlight function illuminates the display and is used when the ambient light to too low to permit viewing of the displayed readings.
Press the (HOLD) button for one second to turn the backlight on and press the button a second time to turn the backlight off.

Manual Ranging
The meter turns on in the auto ranging mode. Press the Range button to go to manual ranging. Each press of the range button will step to the next range as indicated by the units and decimal point location. Press and hold the Range button for two seconds to return to auto ranging. Manual ranging does not function in the AC Current , Diode and Continuity check functions

Battery Replacement

Remove the one rear Phillips head screw
Open the battery compartment
Replace the Requires one “9V” battery (NEDA1604, 6F22 006P)
Re -assemble the meter
