Clamp-on Current Measurements :
Application & Removal of the Jaws
Press the jaw trigger & clamp the jaws around conductor(s) of only one single pole of a circuit for load current measurements. Make sure the jaws are completely closed, or else it will introduce measurement errors. Enclosing conductors of more than one pole of a circuit may result in differential current (like identifying leakage current) measurements. Align the conductors to the Jaws center indicators
(Regular or AmpTipTM indicators where applicable) as much as possible to get the best measuring accuracy. For removal, press the jaw trigger and remove the jaws from the conductors.
Adjacent current-carrying devices such as transformers, motors and conductor wires may affect measurement accuracy. Keep the jaws away from them as much as possible to minimize influence.
WARNING :
This Clamp-on meter series is designed to directly 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. Do not use the meter to measure currents above the rated frequency (400Hz). Circulating currents may cause the magnetic circuits of the Jaws reach a hazardous temperature.

Resistance, BeepLit Continuity & BeepLit Diode :
Inputs are made through the test lead terminals COM/+ .
Defaults at Resistance . Press SELECT button momentarily to select the subject functions in sequence.
TM
BeepLit Continuity :
This function is having improved convenience for checking wiring connections and operation of switches. Resistance threshold is being used. A continuous beep tone together with flashing display backlight indicate a complete wire. Such audible and visible indications improve continuity readabilities in noisy working environments.
TM
BeepLit Diode :
Reading indication : Forward voltage drop (forward baised) for a good silicon diode is between 0.400V to 0.900V. A higher reading indicates a leaky diode (defective). A zero reading indicates a shorted diode
(defective). An over-range display indicates an open diode (defective)
Reverse the test leads connections (reverse biased) across the diode.
The digital display shows over-range if the diode is good. Any other readings indicate the diode is resistive or shorted (defective).
TM
Beep-Alert & BeepLit Indication :
When the display reading drops across 0.850V, the meter alerts a short beep to signal a reasonable forward voltage drop of common diodes. However, if the reading further drops below 0.100V, the meter gives a continuous beep tone together with flashing display backlight to indicate a shorted diode or a complete wire. it is similar to
TM TM that of BeepLit Continuity function but BeepLit Diode , instead, is based on voltage threshold to indicate a complete wire.
14
®
CAUTION :
TM TM
Using Resistance, BeepLit Continuity or BeepLit Diode function in a live circuit will produce false results and may damage the meter. In many cases, the suspected components must be disconnected from the circuit to obtain an accurate measurement reading.

EF-Detection of Electric Field
Defaults at high sensitivity EF-H.
The meter displays “EF-H” when it is ready. If it is too sensitive for your applications, press SELECT button momentarily to select lower sensitivity “EF-L”.
The detected Electric
Field strength is indicated as a series of bar-graph segments on the display plus variable beep tones.
Non-Contact EF-Detection (NCV) : An antenna is located along the top-right end of the stationary clamp jaw, which detects electric field that surrounds energized conductors. It is ideal for tracing live wiring connections, locating wiring breakage and to distinguish between live or earth connections.

The DC A function designed especially for
HVAC/R flame sensor applications. The
0.1
A resolution is useful for identifying the minute current changes in flame detector applications. Flame signal current check should indicate steady flame signal of at least 2 A for a rectification type, or 1.5
A for an ultraviolet type (8 A for self checking systems). If a flame signal current with inadequate strength or fluctuation beyond 10%, check the following to avoid the risk of unwanted flame relay dropout :
For gas or oil flames (Minipeeper) :
Dirty viewing windows
For oil flames (Photocell) :
Detector location & wiring
Smoky flame or poorly adjusted air shutter
Faulty Photocell
Temperature over 165ºF
(74ºC) at photocell
For gas flames (Flame Rod) :
Ignition interference (A flame signal current difference with the ignition both on and off greater than 0.5
A indicates the presence of ignition interference).
Insufficient ground (must be at least 4 times the detector area).
Flame lifting off burner head (ground), or not continuously in contact with the flame rod.
Temperature in excess of 600ºF (316ºC) at the flame electrode insulator causing short to ground.

CAUTION :
Discharge capacitors before making capacitance measurements. Large value capacitors should be discharged through an appropriate resistance load. Using capacitance function in a live circuit will produce false results and may damage the meter. In many cases the suspected components must be disconnected from the circuit to obtain accurate measurement readings.
HOLD :
Press the HOLD button momentarily to toggle the hold feature.

®
Intelligent Auto-Power-Off (APO) :
The Auto-Power-Off (APO) mode turns the meter off automatically to extend battery life after approximately 32 minutes of no specified activities, where applicable, below :
1. Rotary switch or push button operations.
2. Significant measuring readings of above 8.5% of ranges.
3. Non-over-range readings for Resistance, Continuity or Diode function.
