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 III 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
WARNING: Before and after hazardous voltage measurements, test
the voltage function on a known source such as line voltage to
determine proper meter functioning
ACV, DCV, DC+ACV (Models 089 & 088 only), EF (NCV), &
Line-level Hz functions
Inputs, other than that of EF as described below, are made through
the test lead terminals COM/+. Press SELECT button momentarily to
select the subject functions in sequence. Last selection will be saved
as power up default for repeat measurement convenience. Press Hz
button momentarily to toggle the Line-level Hz function.
ote: ACV (and hence AC+DCV & Line-level Hz) function is
equipped with digital low-pass filter, and is capable of dealing with
VFD (Variable Frequency Drives) signals. It also improves ACV
reading stability in noisy electrical environments.

Electric Field EF-Detection
The meter displays “EF” when it is ready. Signal strength is indicated
as a series of bar-graph segments on the display together with
variable beep tones.
● on-Contact EF-Detection: An antenna is located along the top-
right end of the stationary 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 one single probe to test via terminal COM for direct contact EF-
Detection with best sensitivity.

CAUTION & WARNING for Non-Invasive (Clamp-on) Current
Measurements:
CAUTION
(Application and Removal of the Clamp-on Jaws) 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 Align the conductor(s) to
the Jaws center indicators (Regular or AmpTip™ 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
conductor(s)
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
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, Continuity & Diode functions
Inputs are made through the test lead terminals COM/+. Press
SELECT button momentarily to select the subject functions in
sequence. Last selection will be saved as power up default for repeat
measurement convenience.
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
13

Using Resistance, Continuity or Diode 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
14

only) functions
Inputs are made through the test lead terminals COM/+. Last
selection will be saved as power up default for repeat measurement
convenience. Press SELECT button momentarily to select the subject
functions in sequence.
Note
Be sure to insert the banana plug type-K temperature bead probe
Bkp60 with correct polarities You can also use a plug adapter
Bkb32 (Optional purchase) with banana pins to type-K socket to
adapt other type-K standard mini plug temperature probes
CAUTION
1 Using Capacitance function in a live circuit will produce false
results and may damage the meter In many cases the suspected
15

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
DCA Current function (Models 089 & 086 only)
Inputs are made through the test lead terminals COM/+.
Application notes:
The DCA function is 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):
Low supply voltage
Detector location
Defective detector wiring
Dirty viewing windows
Faulty Minipeeper
For oil flames (Photocell):
Detector location & wiring
Smoky flame or poorly adjusted air shutter
Faulty Photocell
Temperature over 165 oF (74 oC) 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
16

Temperature in excess of 600 oF (316 oC) at the flame electrode
insulator causing short to ground.
17

& 3-Phase Rotation function (Models 089 & 086 only)
Inputs are made through the test lead terminals L1/L2/L3. Phase
Rotation directions are indicated as symbolic movements by the LCD
segments. Press SELECT button momentarily toggles between
and modes. Last selection will be saved as power up default for
repeat measurement convenience.
: Hi-sensitivity mode, which detects relatively low signal outputs
generated from motor spinning, for checking phase
connections of Motors.
: ormal-sensitivity mode for identifying phase sequence of
MAI S (electricity supply).
CAUTION
Proper Rotation detection relies on solid signal connection to all
three test lead terminals simultaneously Any single disconnection
will lead to detection failure and may produce false indication To
verify signal connection and hence proper meter indication, swap
any two connects (between the meter and the test points) to check
for indication of reverse movement
18

Using the Hi-sensitivity mode for Motors:
Connect to the Motor as illustrated. Be sure the electricity supply is
removed. From the perspective of looking down the shaft of the
motor, speed-spin it clockwise to generate sufficient signal strength
for proper meter detection. If the meter indicates a clockwise
movement, the motor leads connected to L1, L2 and L3 of the meter
are L1, L2 and L3 (also known as R, S and T), respectively. If the
meter indicates a counter-clockwise movement, swap any two
connects between the meter and motor. Then retest.
Using the Normal mode for MAINS (electricity supply):
Connect to the MAI S as illustrated. If the meter indicates a
clockwise movement, the phases connected to L1, L2 and L3 of the
meter are L1, L2 and L3 (also known as R, S and T), respectively. If
the meter indicates a counter-clockwise movement, swap any two
connects between the meter and phases. Then retest. Connect the
above mentioned L1, L2 and L3 of a Motor and that of the MAI S
respectively should get a clockwise motor movement.
Using the Complementary eeper feature:
The Complementary Beeper feature is selected in Power-up option.
Press and hold the REC button while turning the meter on to enable.
If the segments indicate a clockwise movement, the beeper sounds a
single long beep per segment cycle. If the segments indicate a
counter clockwise movement, the beeper sounds 3 short beeps per
segment cycle.
Hold
Hold feature freezes the display for later view. LCD “ ” turns on.
Press the HOLD button momentarily to toggle the hold feature.
Record mode
Press REC button momentarily to activate MAX/MI /AVG recording
mode. LCD “ ” & “MAX MIN AVG” turn on. The meter beeps when
new MAX (maximum) or MI (minimum) reading is updated. AVG
(Average) reading is calculated over time. Press the button
momentarily to read the MAX, MI and AVG readings in sequence.
