5. OPERATING INSTRUCTIONS

5.1. MEASUREMENT OF AIR TEMPERATURE AND HUMIDITY

Do not carry out any measurements in case gas, explosive materials or
flammables are present, or in dusty environments. Do not expose the in-built
sensor to mechanical shocks.
1. Switch on the instrument using key ON/OFF.
2. Use keys  or  to select the measuring unit for temperature (see § 4.3.3).
3. Position the in-built sensor (see Fig. 1
performed. The value of temperature in real time is shown on the secondary display,
while the value of relative humidity (%RH) in real time is shown on the main display.
Value " - - - " indicates that the maximum measurable values have been exceeded. The
analogue bargraph is not active in this function.
