Terms in this manual

WARNING identifies conditions and actions that could result in serious injury or even death to the user.

CAUTION identifies conditions and actions that could cause damage or malfunction in the instrument.

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.

Keep your hands/fingers behind the hand/finger barriers (of the meter and the test probe assembly, where applicable) that indicate the limits of safe access of the hand-held parts during measurements. Inspect lead wires, connectors, and probes for damaged insulation or exposed metal before using the meter. If any defects are found, replace them immediately.

Only use the probe assembly provided with the meter or a UL Listed Probe Assembly to the same meter ratings or better.

IEC 61010-031 requires exposed conductive test probe tips to be ≤ 4mm for CAT III & CAT

IV ratings. Refer to the category markings on your probe assemblies as well as on the addon accessories (like detachable Caps or Alligator Clips), if any, for applicable rating changes.

Observe proper safety precautions when working with voltages above 33 Vrms, 46.7 Vpeak or 70 VDC. These voltage levels pose a potential shock hazard to the user. Before and after hazardous voltage measurements, check the voltage function on a known source such as line voltage to determine proper meter functioning.

CAUTION

Disconnect the test leads from the test points before changing functions.

Brief Information about Measurement Categories

Measurement Category IV is applicable to test and measuring circuits connected at the source of the building’s low -voltage MAINS installation. Examples are measurements on devices installed before the main fuse or circuit breaker in the building installation.

Measurement Category III is applicable to test and measuring circuits connected to the distribution part of the building’ s low-voltage MAINS installation. Examples are measurements on distribution boards (including secondary meters), circuit-breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other equipment such as stationary motors with permanent connection to the fixed installation.

Measurement Category II is applicable to test and measuring circuits connected directly to utilization points (socket outlets and similar points) of the low-voltage MAINS installation.

Examples are measurements on MAINS CIRCUITS of household appliances, portable tools and similar equipment.

True RMS

4

RMS (Root-Mean-Square) is a term used to describe the effective or equivalent DC value of an AC signal. True RMS is the term which identifies a DMM that responds accurately to the effective RMS value regardless of the waveforms such as: square, sawtooth, triangle, pulse trains, spikes, as well as distorted waveforms with the presence of harmonics. Harmonics may cause :

1) Overheated transformers, generators and motors to burn out faster than normal

2) Circuit breakers to trip prematurely

3) Fuses to blow

4) Neutrals to overheat due to the triplen harmonics present on the neutral

5) Bus bars and electrical panels to vibrate

Crest Factor

Crest Factor is the ratio of the Crest (instantaneous peak) value to the True RMS value, and is commonly used to define the dynamic range of a True RMS DMM. A pure sinusoidal waveform has a Crest Factor of 1.414. A badly distorted sinusoidal waveform normally has a much higher Crest Factor.

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.

AutoV (LoZ) mode

5

AutoV automatically selects measurement function of DCV or ACV, based on their input levels via the test leads. The input also provides a low ramp-up impedance (LoZ) to drain ghost voltages*.

●With no input, the meter displays “ - - - ” when it is ready.

●Whe n a signal above the voltage threshold of 1V DC or AC up to the rated 1000V is present, the meter displays the voltage value in appropriate DC or AC, whichever larger in peak magnitude.

Note:

* Ghost-voltage Buster: Ghost-voltages are unwanted stray signals coupled from adjacent hard signals, which confuse common multimeter voltage measurements. The AutoV mode provides low (ramp-up) input impedance (approx. 2.1

kΩ 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.

*Only HOLD , EF & Backlight push-button features are available in AutoV mode.

WARNING:

6

AutoV mode input impedance increases abruptly from initial 2.1

kΩ to a few hundred kΩ’s on high voltage hard signals . “ LoZ ” displays on the LCD to remind the u sers of being in such low impedance mode. Peak initial load current, while probing 1000VAC for example, can be up to 673mA (1000V x 1.414 / 2.1

kΩ) , decreasing abruptly to approx. 2.4mA (1000V x 1.414

/ 580 kΩ) within a fraction of a second.

Do not use AutoV mode on circuits that could be damaged by such low input impedance. Instead, use rotary selector or high input impedance voltage modes to minimize loading for such circuits.

ACV, DCV & VFD-ACV functions

Press the SELECT button momentarily to select the subject functions in sequence. Last selection will be saved as power up default for repeat measurement convenience.

Note:

VFD-ACV and the associated Hz are equipped with digital low-pass filter (DSP), and are capable of handling VFD (Variable Frequency Drives) signals for fundamental V & Hz readings. It also improves ACV and Hz reading stability when being used in most noisy electrical environments.

Line Frequency functions (Models 237R & 239R only)

7

Press the Hz push-button momentarily to toggle Hz function. It is only available to Voltage and Current related ranges.

Input sensitivity varies automatically with the function range selected while activating the Hz function. 6V function range has the highest and the 1000V range has the lowest. When activated under DCV, ACV or VFD-ACV voltage function, the trigger voltage range will be displayed right before starting the Hz readings. Press momentarily the RANGE button can manually select another trigger voltage range (not available to current ranges). It is recommended to first measure the signal voltage (or current) level and activate Hz function in that range to get the most appropriate trigger level. If the Hz reading becomes unstable, select lower sensitivity to avoid electrical noise. If the reading shows zero, select higher sensitivity.

Resistance, BeepLit TM Continuity & Diode;

Capacitance (Models 237R & 239R only)

Press the SELECT button momentarily to select the subject functions in sequence. Last selection will be saved as power up default for repeat measurement convenience.

8

9

BeepLit TM Continuity function is having improved convenience for checking wiring connections and operation of switches. 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.

In Diode function, the 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

Using resistance and continuity function in a live circuit will produce false results and may damage the instrument. In many cases the suspected component must be disconnected from the circuit to obtain an accurate reading.

CAUTION

Discharge capacitors before making any measurement. Large value capacitors should be discharged through an appropriate resistance load.

ACmV & DCmV; Temperature o C & o F (Model 239R only)

Press the SELECT button momentarily to select the subject functions in sequence. Last selection will be saved as power up default for repeat measurement convenience.

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 standard type-K mini plug temperature probes.

Press SELECT button momentarily to toggle between DC and AC .

Last selection will be saved as power up default for repeat measurement convenience.

Application notes for flame sensors:

DC  A function is useful for HVAC/R flame sensor applications. The 0.1

 A resolution can identify 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 o F (74 o C) at photocell

For gas flames (Flame Rod):

12

 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 600 o F (316 o C) at the flame electrode insulator causing short to ground.

Electric Field EF-Detection (Models 237R & 239R only)

Press the EF button momentarily to toggle EF-Detection feature. T he meter displays “ EF-H ” when it is ready. If it is too sensitive for your applications, press (Level) button momentarily toggles to 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 : An antenna is located along the top-left end of the meter, which detects electric field surrounding energized live conductors. It is ideal for tracing live wiring connections, locating wiring breakages and to distinguish between live and earth connections.

● Probe-Contact EF-Detection : For more precise indication of live wires, such as distinguishing between Live and Ground connections, use direct contact testing with one single test-probe via the input terminal COM or V. The COM terminal (Black) has the best sensitivity.

13

& 3-Phase Rotation function

Inputs are made via 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.

: Normal-sensitivity mode for identifying phase sequence of Electricity Supply.

CAUTION

14

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 (to the meter) to check for meter indication of reverse movement

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 Regular-sensitivity mode for MAINS (Electricity Supplies):

Connect to the MAINS 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 MAINS respectively should be able to get a clockwise motor movement.

Using the Complementary Beeper 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.

MAX/MIN/AVG Record mode

Press REC button momentarily to activate MAX/MIN/AVG recording mode. The LCD “MAX

MIN AVG ” turn on. The meter beeps when new MAX (maximum) or MIN (minimum) reading is updated. Press the button momentarily to read the MAX, MIN, AVG readings in sequence.

Press the button for 1 second or more to exit MAX/MIN/AVG recording mode. Auto-ranging remains, and Auto-Power-Off is disabled automatically in this mode.

Backlighted LCD display

Press the SELECT button for 1 second or more to toggle the LCD backlight. The backlight will also be turned off automatically after 10 minutes to extend battery life.

Hold

15

The hold feature freezes the display for later view. Press the HOLD button momentarily to toggle the hold feature.

Relative Zero ( ) mode

Relative Zero allows the user to offset the meter consecutive measurements with the displaying reading as the reference value. Practically all displaying readings can be set as relative reference value including MAX/MIN/AVG feature readings. Press the button for one second or more to toggle Relative Zero mode.

Manual or Auto-ranging

For most auto-ranging functions (LCD turns on by default), press the RANGE button momentarily to select manual-ranging override. The meter will remain in the range it was in, the LCD turns off. Press the button momentarily again to select the next range. Press and hold the button for 1 second or more to resume auto-ranging.

Note: Manual-ranging feature is not available to AutoV, Capacitance & Hz functions.

BeepJack™ Input Warning

The meter beeps as well as displays “ InEr ” to warn the user against possible damage to the meter due to improper connections to the  A, mA, or A input jacks when another function, especially a voltage function, is selected.

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:

1) Rotary switch or push button operations

2) Significant measuring readings of above 8.5% of ranges

3) Non-OL readings for Resistance, Continuity or Diode function

4) Non-zero readings for Hz function

5) Electric field signal present for EF function

6) Significant movement indication as in Phase Rotation functions

In other words, the meter will intelligently avoid entering the APO mode when it is under normal measurements. To wake up the meter from APO, press the SELECT button momentarily and release, or turn the rotary switch OFF and then back on. Always turn the rotary switch to the OFF position when the meter is not in use
