## Summary description

The Unit UT18E is a handheld voltage and continuity tester featuring an LCD display and non-contact voltage detection. Designed for electricians and technicians, it checks voltage presence and circuit continuity without direct contact, and displays results on the screen for clear readings. It is suitable for troubleshooting, maintenance, and safety checks in residential and commercial electrical work.

## Long description

UNI-T UT18E voltage and continuity tester is a handheld diagnostic tool for measuring AC and DC voltages up to 1000 V, checking phase sequence, verifying circuit continuity and testing operation of residual current devices. The instrument provides readings on an LCD and with backlit LEDs, includes audible indication and a built-in flashlight, and is rated IP65 for dust and splash resistance.
Advantages
The UT18E covers a wide voltage range with automatic polarity recognition for DC measurements, offers continuity checks with sound and light indication, and supports RCD testing at 230 V (50–400 Hz). Additional features such as an LCD showing voltage and frequency, backlighting, silent mode, automatic shut-off and overvoltage protection up to 1100 V improve usability and safety in residential and industrial environments.
Key specifications
Manufacturer: UNI-T
Model: UT18E
Voltage measurement (AC/DC): 6V ±(1.5%＋1); 12V ±(1.5%＋2); 24V ±(1.5%＋2); 50V ±(1.5%＋3); 120V ±(1.5%＋4); 230V ±(1.5%＋5); 400V ±(1.5%＋5); 690V ±(1.5%＋5); 1000V ±(1.5%＋5)
Phase rotation test: 100 V AC–400 V AC (3-phase), 50/60 Hz
Continuity test: 0 Ω–60 kΩ with sound and light indicator

How to use
Connect the tester probes according to the measured circuit, select the required measurement mode and read the value on the LCD or observe the LED indicators. For phase rotation check, measure between phases in a 3-phase system within 100–400 V AC and 50/60 Hz. Use the continuity function to verify circuit paths (0 Ω–60 kΩ) and listen for the audible signal or watch the LED for confirmation. To test RCDs, apply the tester function at 230 V and appropriate frequency range. Follow standard safety procedures: de-energize when required, use protective equipment and observe manufacturer recommendations.
Recommendations
Before each use, inspect probes and housing for damage, replace weak batteries (low battery indication at ~2.4 V), and avoid exposure to fluids beyond IP65 protection. Do not exceed specified overvoltage limits and consult qualified personnel for installation work beyond routine testing.
