8 Operating the Sensistor Sentrac
8.1 Preparation
8.1.1 Battery Operation
The Sensistor Sentrac Portable Model is designed for mobile operation.
For stationary of operation you must do the following:
1 When battery is low, connect the battery charger.
2 Disconnect the battery charger when the battery is fully charged.
3 Reconnect the battery charger to initiate a new charging cycle.
Caution
Do not expose the probe to a hydrogen concentration greater than 0.1% when the
instrument is not powered, as this could damage or destroy the probe sensor.
Caution
When the instrument is put into operation the sensor withstands temporary
exposure to hydrogen concentrations up to 100%. Avoid long exposures to high
concentrations.
Notice During normal use, the leak detector's blue LED light should be steady. If
the LED light is flashing go to Chapter 13 “Troubleshooting” on p. 55.
Ensure that the environment where the leak detection takes place is not
contaminated or close to other hydrogen sources.
Notice The battery charger will not restart automatically when the battery runs
low if you leave battery charger connected.
