Art.no  36-8125  Model  UT18C

Please read the entire instruction manual before using the product and 
then save it for future reference. We reserve the right for any errors in text 
or images and any necessary changes made to technical data. If you 
have any questions concerning technical problems please contact our

Safety

First read the entire instruction manual and make sure that you have 
understood all the information regarding safety and maintenance in order 
to be able to use the voltage tester in a safe way.

 

Warning:

•  The function of the voltage tester should be checked on a known 

voltage source before measuring is commenced.

•  Only grip the test probes by the handles. Never touch the tips of 

the test probes.

•  The voltage tester must only be used on circuits within the specified 

measuring range (690 V).

•  The voltage tester should not be connected to a voltage source for 

more than 30 seconds at a time.

•  Do not use the voltage tester if it is in any way damaged or malfunctioning.
•  Do not use the voltage tester in a wet or humid environment. 

Accurate readings can only be guaranteed within the temperature 
and humidity ranges specified in the Specifications section below.

•  Safety can no longer be guaranteed if the voltage tester does not 

display reliable readings.

•  When using the voltage tester, only touch the gripping surfaces of 

the test probes, never touch the metal tips.

Product description

The UT18C is an advanced voltage tester capable of testing AC and 
DC voltages from 12 V to 690 V. The voltage tester is capable of RCD 
testing, phase sequence testing and continuity testing. It is designed to 
be suitable for use by professional electricians and homeowners alike.

Features

•  Measures alternating current and direct current from 12 V to 690 V
•  Phase sequence test
•  RCD test
•  Continuity test
•  Overvoltage protection for voltages over 690 V AC/DC
•  Has an ingress protection rating of IP65. Dust-tight and water-resistant

Instructions for use

Measuring DC voltage

Touch the tips of the test probes against the object under test.
For voltages over 12 V the voltage tester starts automatically.
If the plus sign lights up, the positive test probe (+) is connected to 
the positive terminal of the object under test.
If the minus sign lights up, the negative test probe (−) is connected to 
the negative terminal of the object under test.
The voltage level is indicated by LEDs: ± 12, 24, 36, 50, 120, 400, and 690.

Measuring AC voltage

Touch the tips of the test probes against the object under test.

Warning

, potential hazard. Follow the instructions in this 

instruction manual.

Continuity (closed circuit test)

RCD test button

The voltage tester should not be disposed of in your bin as 
household waste. The voltage tester should be regarded 
as waste electrical and electronic equipment and taken to 
your local household waste recycling centre for disposal in 
accordance with local regulations. If you are unsure how to 
proceed, contact your local council.

indicator lights up.
The voltage level is indicated by LEDs: ± 12, 24, 36, 50, 120, and 400.

Note:

 If the voltage under test is less than 5 V, the tester may not detect it.
