c) Measuring Humidity
1. Set the selection switch (#2) to the %RH position.
2. Read the measured value from the LCD.
3. The device needs a couple of minutes to catch up when the relative humidity of the tested area changes.
d) Temperature Measurements
1. Set the selection switch (#2) to the 0.1°C or 1°C position.
2. Read the measured value from the display.
3. Insert the temperature probe in the appropriate sockets: black plug in COM, red plug in V/Ω/mA/°C.
4. Touch the target surface with the extremity of the probe and read the measured temperature from the LCD.
e) Voltage Measurements
NOTE: to avoid damage to the device, don't measure values over 600Vdc or ac rms.
1. Set the selection switch (#2) to the desired Vdc or Vac position.
2. Plug the black test lead in COM and the red test lead in V/Ω/mA/°C and put them over the load to be measured.
3. Read the measured value from the LCD. When measuring Vdc, the polarity of the red test lead will be indicated.
f) Current Measurements
NOTE: to avoid damage to the device, don't measure values over the selected value.
1. Set the selection switch (#2) to the desired current measuring position.
2. Plug the black test lead in COM and the red test lead in V/Ω/mA/°C for max. 200mA measurements (fuse
protected) or in 10A (unfused) for max. 10A measurements.
3. Put the leads in series with the load in which the current is to be measured.
4. Read the measured value from the LCD. The polarity of the red test lead will be indicated.
