Issue: If you turn on the I&R check and leave it running while starting the Gas Test, the Laser Portable device will freeze and shut down. The Gas Test will not run.
Answer:
As stated in the manual, the I&R test must be turned off before starting the “Self Check Test” (i.e. “Gas Test”). Leaving the I&R test running will interfere with the Gas Test and cause the device to shut down.
