- This operation erases all data stored in the datalog.
- Note: Once the datalog is cleared, the data cannot be recovered.
- Data Selection allows you to select which types of data are stored and made available when you download your datalog to a computer via ProRAE Studio II (version 1.7.0 or higher) software.
- You can choose any or all of four types of data (you must choose at least one):
- Minimum
- Average
- Maximum
- Real Time
- The instrument offers two options for starting the datalogging process:
- Auto Automatically collects datalog information every time the instrument is sampling until the datalog memory is full.
- Manual Datalogging occurs only when you manually initiate it (see below for details).
- When the instrument is set to Manual Datalog, you can turn datalogging on and off by repeatedly pressing [MODE] and stepping through the screens from the main display until you reach the screen that says “Start Datalog?”
- When you reach the screen that says “Start Datalog?” press [Y/+] to start it. You see “Datalog Started,” confirming that datalogging is now on.
- If datalogging is running, it says, “Stop Datalog?” Press [Y/+] to stop datalogging. Otherwise, press [MODE] to advance to the next screen.
- Date Month (MM) and Day (DD) have two digits each, while the year (YYYY) uses four digits.
- The display’s contrast can be increased or decreased from its default setting. You may not need to ever change the default setting, but sometimes you can optimize the display to suit extreme temperature and ambient brightness/darkness conditions.
- If the QRAE 3 is equipped with a pump, the pump can operate at two speeds, high and low. Running at low speed is quieter, extends pump lifespan, and conserves a small amount of power. There is almost no difference in sampling accuracy. Note: High spee...
- Choose and enter an 8-digit Site ID to uniquely identify the particular site where the instrument is to be used. The first four digits can be an alphabet letter or number, while the last four digits can only be numbers. This Site ID is included in the...
- Note: Advance through the alphabet and numbers (0 through 9) by one with each press of the [Y/+] key. To scroll quickly, hold down the [Y/+] key for as long as you want it to scroll rapidly. Save your changes by highlighting “OK” and pressing [Y/+].
- Enter an 8-digit alphanumeric User ID to uniquely identify a user. This User ID is included in the datalog report.
- Note: Advance through the alphabet and numbers (0 through 9) by one with each press of the [Y/+] key. To scroll quickly, hold down the [Y/+] key for as long as you want it to scroll rapidly. Save your changes by highlighting “OK” and pressing [Y/+].

- This operation sets the zero point of the sensor calibration curve for clean air. It should be performed before other calibrations.
- Note: If you use a zero air cylinder, you must use the QRAE 3 Calibration Adapter (and a T calibration tube if the instrument has a pump). Using a calibration adapter is not necessary for calibration in fresh air.

- 13. Alarms Overview
- In addition, the QRAE 3 alarms if one of the following conditions occurs: battery voltage low, pump blocked, etc.
- When the low battery alarm occurs, there may be approximately 10 minutes of operating time remaining. In this case, it is recommended that you promptly change or charge the battery in a non-hazardous location.

- The instrument is equipped with audible, visible, and vibration alarms. During its normal operation, the PGM-25XX/D compares gas concentrations to the programmed alarm limits for Low, High, TWA and STEL alarms. If the concentration exceeds any of the ...
- When a low-battery alarm occurs, there may be approximately 20 to 30 minutes of operating time remaining. However, it is recommended that you promptly change or charge the battery in a non-hazardous location.

SAFETY INSTRUCTIONS
Read Before Operating
This Manual must be carefully read by all individuals who have or will have the
responsibility of using, maintaining, or servicing this product. The product will perform
as designed only if it is used, maintained, and serviced in accordance with the
manufacturer’s instructions. The user should understand how to set the correct parameters
and interpret the obtained results.
CAUTION!
• Only use RAE Systems battery pack P/N G02-3004-000 (Li-ion, rechargeable)
• Charge the instrument Li-ion battery using the appropriate RAE Systems charger
and only outside hazardous areas
• Use of non-RAE Systems components will void the warranty and can
compromise the safe performance of this product
• Warning: Substitution of components may impair intrinsic safety
SPECIAL CONDITIONS FOR SAFE USE
• The PGM-25XX/D multi-gas detector must be calibrated if it does not pass a
bump test, when a new sensor has been installed, or at least once every 180 days,
depending on use and sensor exposure to poisons and contaminants
• No precautions against electrostatic discharge are necessary for portable
equipment that has an enclosure made of plastic, metal or a combination of the
two, except where a significant static-generating mechanism has been identified.
Activities such as placing the item on a belt, operating a keypad or cleaning with a
damp cloth, do not present a significant electrostatic risk. However, where a
static-generating mechanism is identified, such as repeated brushing against
clothing, then suitable precautions shall be taken, e.g., the use of anti-static
footwear.
Note: Users are recommended to refer to ISA-RP12.13, Part II-1987 for general
information on installation, operation, and maintenance of combustible gas detection
instruments.
