Grounding resistance Taiwan Taishi TES-1605 digital meter
· with the measured ground voltage function
· data locking
Automatic shutdown function: when the meter operation for about three minutes, will automatically shutdown, power savings
· measuring output current: 2mA
· for triode measurement precision, but also can be convenient and simple two-wire measurement
· when auxiliary grounding pin grounding resistance is too high, LCD will display the "warning"
· design conforms to IEC1010-1 safety standard
The measurement range and accuracy (at 23 ℃ and 45-75%RH)
