DIGITAL EARTH TESTER PDR4000 – Sanwa Electric Instrument Co. Ltd.
Easy to read with backlight
・Three measurement ranges: 40Ω, 400Ω, 4000Ω
・3-pole/2-pole earth resistance measurement
(Optional accessory TL-68 is necessary for 2-pole measurement.)
・Auto power off (10 min./Cancelable)

Features
Auto power off
Power is automatically turned off when a certain time has elapsed after power-up. Some models have a function to cancel this function.
Data hold
A value indicated on the display is fixed. It is fixed even after the test lead is removed, and can be used as a record for reference purposes.
Measurement of relative value
A certain measured value is assumed as 0 and measured values after that are expressed by positive or negative values relative the value fixed as 0.
Backlight
Allows indicator reading in a dark place.
