Designed for use in HV work, UNI-T's UT513 can test insulation resistance across a huge range from 500kΩ to 10GΩ.
The meter has fully selectable testing voltages of 100V, 250V, 500V, 1000V, 1500V, 1500V, 2500V and 5000V and is autoranging to make testing selections significantly easier. Generic voltage tests can also be performed up to 1000V for DC voltage and 750V for AC voltage.
Measurements of insulation resistance can be performed either continuously or can be carried out over a set period of time between 00:10 and 15:00 (minutes). Polarisation index (PI) measurements are also possible by using this unit.
The UT513 comes with limited datalogging capabilites and can store up to 18 readings on its built in memory.
