2 GENERAL DESCRIPTION
The instrument HT7052 You purchased, if used in compliance with the indications given in
this manual, guarantees accurate and reliable measurements and the utmost safety
thanks to a development of new conception which ensures double insulation and,
consequently, compliance with the requirements of overvoltage category IV
2.1 INSTRUMENT FEATURES
 High insulation resistance measurement up to 10 T
 Programmable test voltage from 500V up to 10 kV, step 25 V
 R(t) Graphs

 Withstanding voltage (DC) up to 10 kV
 Programmable ramp test voltage from 500 V up to 10 kV
 High resolution ramp (approx. 25 V per step)
 Programmable threshold current up to 5mA
 Voltage and frequency measurement up to 600 V AC/DC
A dot matrix LCD offers easy-to-read results and all associated parameters. The operation
is straightforward and clear to enable the user to operate the instrument without the need
for special training (except reading and understanding this user manual)
Test results can be stored on the instrument. The new professional PC SW enables
straightforward transfer of test results and other parameters in both directions between the
test instrument and PC
