LIGHTNING SURGE PROTECTOR FOR
STRAIN GAUGE USE
Functions & Features
INSTALLATION
• Designed to protect strain gauge transmitters from
lightning surge damage that enters on the wiring between
the strain gauge and the transmitter
• Absorbs surges only without affecting instrumentation
signal

(100 ohms or less)
CROSSOVER WIRE
A crossover wire between M-RESTER ground and the ground or
metallic housing of the equipment is required for protection.
If the protected equipment has no ground terminal, ground the
M-RESTER only.
When the M-RESTER is mounted with DIN Rail Mounting Adapter,
connect the grounding wire to the mounting screw of the M-RESTER.
