RAE Systems QRAE II Quick Start Guide

QRAE II Quick Reference

Covers Diffusion & Pump Models

with Firmware Version 3.12 and higher

WARNINGS

Use only RAE Systems rechargeable battery pack part number 020-3402-000, or alkaline battery pack part
number 020-3403-000. Use only DURACELL MN1500 batteries with alkaline battery pack. This instrument has
not been tested in an explosive gas/air atmosphere having an oxygen concentration greater than 21%.
Substitution of components may impair suitability for intrinsic safety. Recharge batteries only in non-hazardous
locations. Do not connect the serial communication port in a hazardous location.

STATIC HAZARD: Clean only with a damp cloth.
For safety reasons this equipment must be operated and serviced by qualified personnel only. Read and

understand instruction manual completely before operating or servicing. Only the combustible gas detection
portion of this instrument has been assessed for performance.

All newly purchased RAE Systems instruments should be bump tested by exposing the sensor(s) to known
concentration calibration gas before the instrument is put into service, and later, prior to each use. A bump test is
defined as a brief exposure of the monitor to the calibration gas and the sensors to show response and trigger the
lowest alarm set point for each sensor.

• The QRAEII Multi Gas detector must be calibrated if it does not pass a Bump Test, or at least once

every 180 days, depending on use and sensor exposure to poisons and contaminants.

• Calibration intervals and bump test procedures may vary due to national legislation.

• When using an H2S sensor in a QRAE II, RAE Systems recommends using RAE calibration gas

cylinders with a 4 gas mix containing 10 ppm H2S, 50 ppm CO, 50% LEL Methane, and 18% Oxygen.

Any rapid up-scale reading followed by a declining or erratic reading may indicate a gas concentration
beyond upper scale limit which may be hazardous.

Setting Up The Charging Cradle

1. Remove the plastic
spacer piece from
adapter’s receptacle.

2. Select the correct plug
for your region.

3. Tilt the plug into the adapter’s receptacle,

aligning the small ledge with the cutout inside
the receptacle.

4. Connect the
adapter’s plug to the
receptacle on the
back of the cradle.

5. If you need to remove the plug, slide the capture plate to release the plug,
and tilt out the plug from the receptacle.

Before charging the rechargeable Li-ion battery, you must set up the charging cradle. Its AC/DC adapter is
designed for use anywhere in the world and is able to handle voltages between 100 VAC and 240 VAC at either
50 Hz or 60 Hz. It comes with several plugs that snap into place on the base of the AC/DC adapter.

Charging The Battery

Always charge the QRAE II before use. To charge the QRAE II:

1. Plug the AC/DC adapter into the QRAE II’s cradle.

2. Plug the AC/DC adapter into the wall outlet.

3. Place the QRAE II into the cradle and press down until the
charging LED glows.

Green charging LED: Unit charged

Note: A full recharge of the Li-ion battery typically
requires six hours.

Turning The QRAE II On

Hold down [MODE] for 2 seconds. When starting up, the QRAE II simultaneously turns the backlight on and
off, beeps once, blinks once, and vibrates. It performs diagnostics and tells you current settings.

Turning The QRAE II Off

Press and hold [MODE]. In 2 seconds, a 5-second countdown to shutoff begins. You must hold your finger on
the key for the entire shutoff process. If you remove your finger from the key during the countdown, the shutoff
operation is canceled and the QRAE II continues normal operation.
