Note:
Alternatively, frequency measurement can be performed by
entering
AC V
or
AC A
mode using the
Hz%
button.
Power factor (duty factor) is the ratio of the
length of a signal and its repetition time (cycle time)
as a percentage value. If for example the cycle time
of a signal is 100ms and the signal length is 20ms,
then the duty factor is: 20ms:100ms x 100 = 20%.

MEASUREMENT OF TEMPERATURE AND RELATIVE HUMIDITY
When the device is turned ON – in the upper corner of the display – the actual ambient temperature and humidity values are shown
continuously. When the device is moved into the premises to be measurement from a much different environment, it is recommended
to wait 15 minutes before reading any measurements. This is necessary for example when the device is taken indoors from a cold
environment during winter, as the device needs to first warm up to the actual ambient temperature. The device is not suitable for
measuring rapidly changing temperature values.
In order to display the temperature in the main display section, touch the thermometer probe accessory to a surface to be measured.
This measurement range is wider than the one integrated into the device. This way, the multimeter can measure two different
temperature values.
The measurement range of ambient temperature measurement is: between 0-40 Celsius. The respective value is shown on the display
but the accuracy of the reading cannot be guaranteed. Use the thermometer probe in these cases.
1. Turn the dial button to the
TEMP
position.
2. Connect the cables of the type "K" thermometer probe to the device. (Connect the red cable to the
mATemp
jack, and the black
cable to the
COM
jack.)
3. Touch the end of the probe to the object or liquid surface to be measured.
4. Change the measurement unit as necessary using the
0
C/
0
F
buttons.
Note:
Do not touch the probe to a powered circuit or charged capacitor, etc. Caution! Danger of electric shock! Damage can occur to the device!
