WARNING
To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. The meter is intended only for indoor use.
To avoid electrical shock hazard, observe the proper safety precautions when working with voltages above 60 VDC or 30 VAC rms. These voltage levels pose a potential shock hazard to the user. Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning.
Keep your hands/fingers behind the hand/finger barriers (of the meter and the test leads) that indicate the limits of safe access of the hand-held part during measurement. Inspect test leads, connectors, and probes for damaged insulation or exposed metal before using the instrument. If any defects are found, replace them immediately. Only use the test lead provided with the equipment or UL Listed Probe Assembly rated CAT IV 1000V or better.
This Clamp-on meter is designed to apply around or remove from uninsulated hazardous live conductors. But still, individual protective equipment must be used if hazardous live parts in the installation where measurement is to be carried out could be accessible.
CAUTION
Disconnect the test leads from the test points before changing meter functions.

4) OPERATION
CAUTION: Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning.
AutoCheckTM mode This innovative AutoCheckTM feature automatically selects measurement function of
ACV
Hz
, DCV, or Resistance (ΩΩΩΩ) based on the input via test leads.
●With no input, the meter displays “Auto” when it is ready.
●With no voltage signal but a resistance below 10MΩ (nominal) is present, the meter displays the resistance value. When the resistance is below the “Audible Threshold”, the meter further gives a continuity beep tone.
●When a signal above the voltage threshold of 1.5V DC or AC up to the rated 1000V is present, the meter displays the voltage value in appropriate DCV or ACV, whichever larger in peak magnitude.
Note: *Range-Lock and Function-Lock Feature: When a measurement reading is being displayed in AutoCheck
TM
mode, press the RANGE or SELECT button momentarily 1
time can lock the range or function it was in. Press the button momentarily repeatedly
Page 6

to step through the ranges or functions. *As Hazardous-Alert: When making resistance measurements in AutoCheckTM mode, an unexpected display of voltage readings alerts you that the object under test is being energized. *Ghost-voltage Buster: Ghost-voltages are unwanted stray signals coupled from adjacent hard signals, which confuse common multimeter voltage measurements. Our AutoCheckTM mode provides low (ramp-up) input impedance (approx. 2.5kΩ at low voltage) to drain ghost voltages leaving mainly hard signal values on meter readings. It is an invaluable feature for precise indication of hard signals, such as distinguishing between hot and open wires (to ground) in electrical installation applications.
WARNING: AutoCheckTM mode input impedance increases abruptly from initial 2.5kΩ to a few
hundred kΩ’s on high voltage hard signals. “LoZ” displays on the LCD to remind the users of being in such low impedance mode. Peak initial load current, while probing 1000VAC for example, can be up to 566mA (1000V x 1.414 / 2.5kΩ), decreasing abruptly to approx. 3.37mA (1000V x 1.414 / 420kΩ) within a fraction of a second. Do not use AutoCheckTM mode on circuits that could be damaged by such low input impedance. Instead, use rotary-switch selector or high input impedance voltage modes to minimize loading for such circuits.
VFD-ACV
Hz
& ACV
Hz
functions
Inputs are made through the test leads terminals.
VFD-ACV
Hz
function is to deal with VFD (Variable Frequency Device) signals. It, however, further pre-selects the most appropriate voltage-ranges and thus the Hz trigger levels to best cope with most VFD-Voltage and VFD-Frequency applications.
Note: The Hz trigger level is determined by the AC/DC+AC Voltage or Current function-range being in use. Press RANGE button to select
different
function-ranges
and thus
trigger levels manually.
DCV & DC+ACV
Hz
(Model 197 only) functions
Inputs are made through the test leads terminals. Defaults at DCV Function. Press SELECT button momentarily and release to select DC+ACV

CAUTION (Application and removal of the Clamp-on meter)
For non-invasive current measurements, press the jaw trigger and clamp the jaws around conductor(s) of only one single pole of a circuit for load current measurement. Make sure the jaws are completely closed, or else it will introduce measurement errors. Enclosing conductor(s) of more than one pole of a circuit may result in differential current (like identifying leakage current) measurement. Locate the conductor(s) at the Jaws center as much as possible to get the best measuring accuracy. For removal, press the jaw trigger and remove the jaws from the conductor(s).
Adjacent current-carrying devices such as transformers, motors and conductor wires will affect measurement accuracy. Keep the jaws away from them as much as possible to minimize influence.
ΩΩΩΩ Resistance & Continuity functions
Inputs are made through the test leads terminals. Defaults at ΩΩΩΩ Resistance. Press SELECT button momentarily and release to select. Continuity
Capacitance & Diode functions
Inputs are made through the test lead terminals. Defaults at Capacitance. Press SELECT button momentarily and release to select Diode.
Note
When using Diode test function, normal forward voltage drop (forward biased) for a good silicon diode is between 0.400V to 0.900V. A reading higher than that indicates a leaky diode (defective). A zero reading indicates a shorted diode (defective). An OL indicates an open diode (defective). Reverse the test leads connections (reverse biased) across the diode. The digital display shows OL if the diode is good. Any other readings indicate the diode is resistive or shorted (defective).
CAUTION
1. Using Resistance, Continuity, Diode or Capacitance function in a live circuit will produce false results and may damage the meter. In many cases the suspected component(s) must be disconnected from the circuit to obtain an accurate measurement reading.
2. When using Capacitance function, discharge capacitor(s) before making any measurements. Large value capacitors should be discharged through an appropriate resistance load

Electric Field EF-Detection
In Voltage or Current function, press the EF button momentarily and release to toggle to EF-Detection feature. The meter displays “E.F.” when it is ready. Signal strength is indicated as a series of bar-graph segments on the display together with variable beep tones.
●Non-Contact EF-Detection: An antenna is located along the top-right end of the clamp jaw, which detects electric field surrounds energized conductors. It is ideal for tracing live wiring connections, locating wiring breakage and to distinguish between live or earth connections.
●Probe-Contact EF-Detection: For more precise indication of live wires, such as distinguishing between live and ground connections, use the Red (+) test probe for direct contact measurements.

5) MAINTENANCE WARNING
To avoid electrical shock, disconnect the meter from any circuit, remove the test leads from the input jacks and turn OFF the meter before opening the case. Do not operate with open case.
Trouble Shooting
If the instrument fails to operate, check batteries and test leads etc., and replace as necessary. Double check operating procedure as described in this user’s manual.
If the instrument voltage-resistance input terminal has subjected to high voltage transient (caused by lightning or switching surge to the system under test) by accident or abnormal conditions of operation, the protective impedance components in series might be blown off (become high impedance) like fuses to protect the user and the instrument. Most measuring functions through this terminal will then be open circuit. Such components should then be replaced by qualified technician. Refer to the LIMITED WARRANTY section for obtaining warranty or repairing service.
Accuracy and Calibration
Accuracy is specified for a period of one year after calibration. Periodic calibration at intervals of one year is recommended to maintain meter accuracy. Refer to the LIMITED WARRANTY section for obtaining calibration, repairing or warranty service.
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 periods of longer than 60 days, remove the batteries and store them separately.
Battery replacement
The meter uses standard 1.5V AA Size (IEC LR6) battery X 2
