  • Blister card.

HUMIDITY AND AIR TEMPERATURE MEASUREMENTS

  1. Hold the probe in the area to be tested and allow adequate time for readings to stabilize.
  2. Press °F, °C, dew point, WBT and select enter key and further select °F, °C, dew point Wet Bulb measurement.
  3. Read the Relative Humidity and Air Temperature, dew point temperature and wet bulb temperature.

NOTE:

Do not immerse the probe in liquid; it is intended for use in air only.

WARNING:

  • Don’t expose the sensor to direct sunlight.(insolation)
  • Don’t touch or manipulate the sensor

Battery Replacement

When the low battery symbol appears on the display, replace the meter’s battery (9V). The battery compartment is located behind the panel that surrounds the meter’s trigger. Open the compartment, replace the 9V battery and close the battery compartment cover

Over-range Indication

If the temperature measurement exceeds the specified temperature range, the thermometer will display dashes in place of a temperature reading.

To override Auto Power Off function (Non-Sleep Mode):

Press the hold/backlight button and press the power button now the full display appears, release both the buttons. Power Icon will not show on the LCD. The unit will not auto power off now.

Over-range Indication

If the temperature measurement exceeds the specified temperature range, the thermometer will display dashes in place of a temperature reading.
