6.7. Frequency measurements
1. Set the rotary selector switch to the Hz position.
2. Plug the black and red test leads into the COM and Hz input
terminals respectively.
3. Determine that the amplitude level of the signal to be
measured is not greater than the input voltage limit (250 V
AC/DC). The signal amplitude must also be greater than the
sensitivity level.
4. Attach the probe tips to the points across which the frequency
is to be measured, and read the result directly from the
display.
5. Disconnect the test leads from the instrument.
6.8. Temperature measurements
1. Set the function switch to TEMP position. The meter
automatically defaults to °C range.
2. Insert the meter´s white temperature adaptor into the V/Ω-
input terminal and the COM-terminal. Ensure that the minus
marking at the adaptor is inserted into the COM-terminal and
the plus-marking is inserted into the V/Ω-input terminal.
3. To change the measuring unit from °C to °F press the MODE-
button to select the °F unit.
4. Connect the K-type probe into the meter adaptor and measure
the temperature of the apparatus or area required.
5. Read the temperature directly from the display.
