(1) In order to eliminate the noise interference, which might be induced to the test leads, it is recommended to use a

shielded test cable for measuring resistance above 120 kΩ

Measurement method: AC coupled true RMS, measuring the AC component only

Input protection: Externally accessible 2 A / 250 V fuse protecting the low input current terminal (LO). Internally accessible 20 A / 250 V fuse protecting the

high current input terminal (10A)

Max. crest factor: 3.0 at full scale

Input protection: 1000 Vdc or 750 Vac for all ranges

Note: Rx is the measured resistance value

For 0.1 PLC (Fast)

Input protection: 1000 Vdc or 750 Vac

For 1 PLC (Medium)

Input protection: 1000 Vdc or 750 Vac for all ranges
