4) OPERATION
WARNING
Before and after hazardous voltage measureme n ts, test the voltage function on a known source such as line voltage to
determine proper meter functioning
ACV(LPF added), & Line-level Hz(LPF added)
Inputs are made via the test lead terminals COM/+. Defaults at ACV
Function. Press the SELECT button momentarily to select Line-level
Hz function.
12
-
®
Note: ACV and Line-level Hz functions are bundled with LPF lowpass filter, and are capable of dealing with most VFD (Variable
Frequency Drives) signals. It also improves reading stability in noisy electrical environments.
DCV
Inputs are made via the test lead terminals COM/+.
Current Measurments: Application & Removal Of The Fork-clamp
Apply the Fork-clamp around conductor(s) of only one single pole of a circuit for load current measurements. Applying around
conductors of more than one pole of a circuit may result in differential
current (like identifying leakage current) measurements. Align the to get the best measuring accuracy. For removal, remove the Fork-
clamp from the conductor(s).
Adjacent current-carrying devices such as transformers, mo tors and conductor wires may affect measurement accuracy. Keep the Forkclamp away from them as much as possible to minimize influence during measurements.
WARNING r ctly apply a round or remove from uninsulated hazardous live conduc tors. 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 u se the meter to measure currents above the rated frequency (400Hz). Circulating currents may cause
temperature.

Fork-clamp ACA
Input is made via the Fork-clamp where best accuracy is spec i fi ed at the center indicator area.

Diode
Inputs are made via the test lead terminals COM/+ . Defaults at

●
This function is having improved convenience for checking wiring connections and operation of switches. Resistance threshold is
being used . A continuous beep sound together with display
backlight flashing indicates a complete wire. Such aud ible and
visible indications improve continuity readabilities in noisy working
environments.
●
Reading indication:
Forward voltage drop (forward biased) for a good silicon diode is
between 0.400V to 0.900V. A higher reading indicates a leaky diode
(def ective). A zero reading indicates a shorted dio de (defective).
An over - range display indicates a open diode (defective). Reverse
the test leads connections (reverse biased) across the
15
®
diode. The digital displ ay shows over - range If the diode is good.
(defective).
● Beep-Alert & BeepLit indication: When the display reading drops across 0.850V, the meter alerts a short bee p sound to signal a reasonable forward voltage drop o f common diodes. However, if the reading further drops below 0.100V,the meter gives a continuous beep sound together with the display backlight flashing to indicate a shorted diode or a complete wire. It is similar to that o f BeepLit
TM
Continuity function but BeepLit Diode , instead, is based on voltage threshold to indicate complete wires.
CAUTION Using Resistance , BeepLit Continuity or BeepLit
Diode function in a live circuit will produce false results and
under test must be disconnected from the circuit to obtain an
accurate
EF-Detection of Electric Field
Defaults at EF-H , the High sensitivity. The meter displays “EF-H”
when it is ready. If it is too sensitive for your applications, press the
SELECT button momentarily to select EF-L , the Low sensitivity. The
segments on the display plus variable beep sounds.
● Non-Contact EF-Detection (NCV): which detects the electric field surrounds energized conductors. It is ideal for tracing live wiring connections, locating wiring breakag e s and to distinguish between live and earth connections.
16
®
● Probe-Contact EF -Detection (Single-pole):
For more precise indication of liv e wires, such as distinguishing
between Live and Ground connections, use one single test probe
to test via terminal COM for direct metal contact probing to achieve
the most distinctive indications.
17
®
DC m A
Inputs are made via the test lead terminals COM / + .
●Application notes:
The DC A function is designed especially for HVAC/R flame sensor applications. 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 m 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):
● Low supply voltage
● Detector location
● Defective detector wiring
●
●
Dirty viewing window
Faulty Minipeeper
For oil flames (Photocell):
●
●
Detector location & wiring
Smoky flame or poorly adjusted air shutter
●
●
Faulty Photocell
Temperature over 165 oF (74 C) at photocell
For gas flames (Flame Rod):
● Ignition interference (A fla me signal current difference with the of ignition interference)
18
®
● Insufficient ground (must be at least 4 times the detector area)
● Flame lifting off burner head (ground), or not continuously in contac t with the flame rod
●
insulato r causing short to ground.
Capacitance & Temperature
Inputs are made via the test lead terminals COM / + . Defaults at
Capacitance. Press the SELECT button momentarily to select °C
(Celsius) and °F (Fahrenheit) in sequence ( °F selection can be left out as factory calibration default for countries that only accept metric
units).
19
®
CAUTION
Discharge capacito r (s) before making capacitance measurements.
Large valu e capacitors should be discharged through an appropr i a t e resistance load . Using Capacitance function in a live
circuit will produce false resul t s and may damage the meter. In
many cases the suspected comp o nent (s) must be disconnected
from the circuit to obtain accurate measurement readings.
Note
Be sure to insert the banana- plug type -K temperature bead-probe
Bkp60 with correct polarities. Banana-pins to type -K socket adapter Bkb32 (Optional purchase) can be used to accept other type-K probes using standard miniature plugs.
Temperature accuracies assume meter interior has the same temperature (isothermal stage) of the ambient, particularly the plug
of the probe being used, for a correct junction voltage compensation.
Allow the meter interior temperature to atch up with that of the plug
after a sudden change of measuring environmen t and hence the
ambient temperature. This can take up to an hou, r for changes > 5°C,
within a low ventilated sturdy meter housing. The uncompensated
temperature differences, if any, will be reflected as off sets on the
meter readings.
