Voltage Test

A voltage test is the main function of the Tester. The

T90 and T110 have an LED bargraph indication to

show the nominal voltage levels. The T130 and T150

also show the values in the LCD.

Connect the two test probes to the UUT to do a

voltage test.

Above 12 V the Tester turns on automatically. For the

T130 and T150, the LCD comes on at 6 V. The backlit

LEDs show the nominal voltage level, for example

v or w.

For the T130 and T150, the voltage is measured

and the value is shown on the LCD as for example,

227 j.

The voltage value on the LCD must not be used to

validate a zero voltage. Always use the LED bargraph.

For ac voltages, the

a LED and the j symbol in

the LCD (T130/T150) illuminates. For dc voltages, the

polarity of the display voltage refers to the instrument

test probe with the D and E LEDs or the

symbol in the LCD (T130/T150). For voltages that

are more than the ELV limit (>50 V ac or >120 V dc),

z comes on in the display. The voltage LED

bargraph and the >ELV indicator must not be used for

measurements. For measurements you can use the

LCD on the T130/T150 to see the actual value.

Voltage Test with Switched Load, RCD

Trip Test (T110/T130/T150)

During voltage tests, you can decrease the

interference voltages from inductive or capacitive

coupling by loading the UUT with a lower impedance

than the Tester has in normal mode. In systems with

RCD circuit breakers, you can trip an RCD switch

with the same low impedance as when you measure

voltage between L and PE (see Figure 5).

To do an RCD trip test during voltage measurement,

push the two

h buttons at the same time. If you have

10 mA or 30 mA RCDs between L and PE in a 230 V

system, it will trip.

During load current, the indicator probe side vibrates

and the

g LED is the indication for the owing load

current. This indication is not to be used for voltage

test or measurement.

Due to low impedance, this circuit is overload-

protected and will decrease the load current after

20 seconds @ 230 V and after 2 seconds @ 690 V.

If the two pushbuttons are not used, the RCDs will not

trip, even in measurements between L and PE.

Single‑Pole Phase Test

To do a single-pole phase test:

1. Firmly hold the indicator probe around its body

(between the nger guard and cable).

2. Touch the probe tip to an unknown contact to nd

the conductor.

a turns on when the ac voltage is >100 V and

you hear the beeper (T110/T130/T150 only).

For a single‑pole phase test to nd external

conductors, the display function operates unreliably

in some conditions. An example is insulated body

protective equipment on insulated locations, such as a

PVC oor or berglass ladder.

The Tester operates without a touch electrode and is

usable when you wear gloves. The single‑pole phase

test is not meant to nd if a conductor is live or not.

For this function, always use the Voltage test.

Continuity/Diode Test

To do a continuity test of cables, switches, relays,

bulbs, or fuses:

1. Do a Voltage test to make sure the UUT is not live.

2. Connect the two test probes with the UUT. You will

hear the beeper if it is on (T110/T130/T150 only)

for continuity and

f is on.

The test voltage/current polarity for a diode test at the

non-indicator test probe is positive + and the indicator

test probe is negative -.

Note

The Tester automatically goes into the voltage

measurement mode if voltage is sensed.

Beeper (T110/T130/T150)

For Continuity, AC Voltage, and Single‑Pole Phase

Test modes, you can turn the beeper on or off:

1. Push and hold cp for 2 seconds to turn the

beeper on.

2. Push and hold cp for 2 seconds to turn the

beeper off.

The status shows together with Volt, Continuity, or

Single‑Pole Phase indications in the LED or LCD.

The beeper mode is stored until you change it. Always

do a continuity test (touch probe tips together) to

make sure that the beeper operates before you start

a test.

In work areas with high background noise, make sure

you can hear the beeper before you start a test.

Resistance Test (T150)

The Tester measures low ohm resistances between

1 Ω and 1999 Ω at a resolution of 1 Ω.

To do a resistance test:

1. Do a Voltage test to make sure the UUT is not live.

2. Connect the two test probes with the UUT. Push

and hold Il for 2 seconds and read value

on the display.

3. Push and hold Il for 2 seconds to turn the

function off.

To save battery power the function automatically

turns off after 30 seconds. The Tester automatically

goes into the voltage measurement mode if voltage

is sensed.

Display HOLD

(T130/T150)

The T130 and T150 include a Display HOLD function

for the LCD.

To use the Display HOLD function:

1. Push HOLD to freeze the LCD while in a Voltage

or Resistance measurement. The status is shown

in the display with a HOLD symbol.

2. Push HOLD again to unfreeze the LCD.

To save battery power the Display HOLD function

automatically turns off after 30 seconds.

Rotary Field Indication

(T110/T130/T150)

The Tester has a double‑pole rotary eld indicator.

The 3rd pole is capacitively-coupled into the unit from

the user’s hand. The Tester operates without a touch

electrode and is also usable when you wear gloves.

q and r display for ac voltage measurements,

but the rotary direction is found only in a three-phase

system. In parallel, the Tester reads the voltage

between two external conductors.

To use the rotary eld indicator:

1. Connect the test probe with the phase L1 and the

indicator probe with the phase L2.

2. Firmly hold the indicator probe around its body

(between the nger guard and cable).

The voltage and the rotary eld direction show on the

display.

r (see Figure 6) signies that the supposed

phase L1 is the actual phase L1 and the supposed

phase L2 is the actual phase L2 right rotary eld.

q (see Figure 7) signies that the supposed phase

L1 is the actual phase L2 and the supposed phase L2

is the actual phase L1 left rotary eld. A retest with

exchanged test probes will cause the opposite symbol

to illuminate.

Torch and Backlight

(T110/T130/T150)

The T110/T130/T150 include a torch and backlight

function. This function is helpful in areas with

unsatisfactory light, for example, division switch

cabinets.

To use the torch or backlight:

1. Push c to turn the torch and backlight on.

2. Push c again to turn the torch and backlight off.

To save battery power the function automatically turns

off after 30 seconds.
