Touch a conductor with the test probe "L2" of the large handle. When a phase (pole >100 V AC), min. 100 V~, is applied, the display "<L"
shows the warning triangle and the red flashing LED as well as a vibration.
For the determination of the phase conductors, the perceptibility of the indication can be impaired, e.g. by insu-
lating devices to protect against direct contact, in unfavorable positions, for example on wooden ladders or in-
sulating floor coverings, a non-grounded voltage or also in unfavorable lighting conditions.
For safety, perform a two-pole check to ensure that no voltage is present.
You can also determine the phase by checking the phase conductor against the protective earth conductor. For the phase conduc-
tor, the applied voltage should be displayed.
Make sure that an additional current flows via the protective conductor during this test. This adds to the current
already present and could trigger the circuit breaker (FI))!
Rotary field test (> 170 V AC)
Protective clothing and insulating locations can affect the function.
Fully enclose handles L1 and L2 (see picture on page 7) below the mechanical mark.
Place the test probes L1 and L2 on two outer conductors (phases) and check whether the outer conductor voltage of e.g. 400 V is
present.
A clockwise rotation sequence (phase L1 before phase L2) is given when the letter "R" appears in the display
A counterclockwise rotation sequence (phase L2 before phase L1) is given when the letter "L" appears in the display.
The rotating field determination must always be performed with the test probes reversed. The direction of rotation must change.
Notice:
The rotating field test is possible from 170 V, 50/60 Hz (phase against phase) in the grounded three-phase network.
The "third" phase (L3) is simulated by grasping the hand parts with the aid of a sensor in the device.
One-hand test (e.g. earthed socket)
The test leads can be plugged into the top of the TV 230 by means of the hook located on the collar of the test lead. The distance
between the test probes is 19 mm, which is ideal for testing conventional sockets with one hand.
Test location lighting
The test location illumination is switched on or off again by pressing the light key for a longer time.
Use them carefully, as the additional load will drain the batteries prematurely.
Backlight
The display backlight turns off automatically after a few seconds to save battery power and turns on again when the key is pressed.
Frequency display
The On/Off function key can be used to switch through to the frequency display. In the frequency display, the unit of measurement
Hz is displayed on the LCD. If both test probes are connected to the test object, the device displays frequencies between 1 and 800
Hz. A frequency is only displayed if a voltage of at least 10 V is applied. The voltage is additionally displayed via the LEDs from a
value of 120 V and the ELV LED indicates voltages >50VAC or >120VDC.
Cleaning
If the device has become dirty through daily use, the device can be cleaned with a damp cloth and some mild household cleaner.
Never use harsh cleaners or solvents for cleaning.
To avoid electrical shock, do not allow moisture to enter the housing.
Maintenance
The device does not require any special maintenance except for the batteries when operated according to the operating instruc-
tions.
