The HK235E High-Voltage Two-Pole Tester extends the series into applications requiring DC measurements above the conventional 1000V level. Its LCD handles 1-1000V AC and up to 1500V DC, making it the appropriate HK235 option when the measured system may exceed the DC capability of the HK235C.
Nine LED voltage steps provide a rapid visual reference from 12V through 1500V. The display responds in one second or less, while the LED indication reacts within half a second. This arrangement helps technicians make efficient voltage checks without relying on a single type of display.
Beyond voltage measurement, the HK235E checks resistance, conductor continuity, three-phase sequence and single-pole voltage. It can also apply a 30mA load at 230V for RCD trip testing. Audible, visual and vibration feedback give the user several ways to recognize a test condition.

FAQ
What is the main difference between the HK235E and HK235C?
The HK235E extends LCD DC voltage measurement and LED indication to 1500V. The HK235C is limited to 1000V DC.
Can the HK235E measure 1500V AC?
No. The supplied specification lists a maximum of 1000V AC and 1500V DC.
Does the tester need batteries for every voltage check?
The specification confirms battery power for its electronic functions. Operating behavior with depleted or removed batteries should be verified in the official user manual before use.
