PRE-USE CHECKS, FRESH AIR ADJUSTMENT AND BUMP TEST
DIFFUSION
No pump and no hose — this monitor measures the air touching its own sensor,
which is the air you are standing in. It is a personal exposure monitor, not a
pre-entry test instrument.

Hold POWER three seconds to switch on. Hold RESET in clean air to run the fresh air adjustment. MODE steps through PEAK / STEL / TWA / ALARM-P / BUMP. RESET clears a latched alarm — but only once you have actually left the gas.
