Introduction

Use this guide to power up your monitor and warm up your sensor head. It assumes the battery is connected and fully charged.

  1. Press and hold the POWER button until the screen activates. If the monitor doesn't power up, the battery may be flat or have become disconnected from the socket at the base of the monitor.
    • Press and hold the POWER button until the screen activates.

    • If the monitor doesn't power up, the battery may be flat or have become disconnected from the socket at the base of the monitor.

    • At startup, the display shows the model number, the software version and the battery type.

    • After 5 seconds, it enters warming up mode, which allows the sensor to burn off any contaminants.

  2. There are two stages of warmup:
    • There are two stages of warmup:

    • 3 MINUTES Display shows the sensor head type and the words WARMING UP but no measurement. Note: The monitor ID (M) and location ID (L) also show for Series 500 and 300 monitors.

    • 7 MINUTES. Sensor is stabilizing and the measurement is flashing.

    • If the sensor is new (or has been unused for a long period), it can take up to 24 hours for the words WARMING UP to disappear. In this situation, try running the sensor in a clean air environment. If the message remains up to 48 hours after startup, a sensor failure may have occurred and you should contact Customer Support.

  3. For an ozone sensor, 24 hours is a conservative time to burn off contaminants to achieve its stated specification.
    • For an ozone sensor, 24 hours is a conservative time to burn off contaminants to achieve its stated specification.

    • VOC in the sample is the most common cause of longer warm up times. VOCs are often present in indoor areas where they are released from carpets, paints and clothing.

    • The warm-up period can be reduced by subjecting the sensor to elevated ozone levels for a short period. For example, 0.1ppm of ozone for 5 minutes can reduce warm-up to less than 30 minutes.

    • Taking the monitor with ozone sensor head outside or opening a window and having the sensor sample outdoor air should speed up the warm up cycle.

  4. When warm up is complete, the measurement stops flashing. If a temperature and relative humidity sensor is fitted, those values appear in separate rows.
    • When warm up is complete, the measurement stops flashing.

    • If a temperature and relative humidity sensor is fitted, those values appear in separate rows.

    • Only 3 parameters can be shown on the screen at one time. If a sensor captures more than one parameter (e.g. PM2.5 /PM10 sensor head) they will scroll up the screen.
