Frequency Measurement
Warning:
To avoid the risk of personal injury, do not attempt to measure frequency with
voltage higher than 30V RMS.
To measure frequency, connect the meter as follows:
•
Insert the red test lead into the Hz terminal and the black test lead into the COM
terminal.
•
Set the rotary switch to Hz%mV and press SELECT button to select Hz
measurement mode.
•
Connect the test leads across with the object being measured. The measured
value shows on the display.
•
When frequency measurement is complete, disconnect the test leads from the
circuit under test.
Note:
When making frequency measurements, the measured signal “a”, must fall
within the following voltage level:
10Hz ~ 1MHz
150mV ≤ a ≤ 30V rms
> 1MHz ~ 10MHz
300mV ≤ a ≤ 30V rms
> 10MHz ~ 50MHz
600mV ≤ a ≤ 30V rms
> 50MHz
Unspecified
Temperature Measurement
To measure temperature, connect the meter as follows:
•
Set the rotary switch to ºCºF to measure temperature. ºC is default, press SELECT
to change to ºF. The display shows OL initially.
•
Short the test leads to show room temperature.
•
Insert the point contact temperature probe into the corresponding Hz and COM
terminal.
Note:
The Meter displays a fixed value which is the value of the meters own internal
circuitry. To ensure accuracy, it is necessary to subtract this value from the displayed
value when measuring small capacitors.
•
Connect the test leads across with the object being measured. The measured
value shows on the display.
•
The multi-purpose socket can be used instead of test leads. Insert the capacitor
being tested into the corresponding input terminal of the multi-purpose socket.
This will provide a more accurate reading when measuring small capacitor values.
•
When measuring capacitance values larger than 600uF, it is normal for the meter
to require some time to stabilize.
•
The LCD displays OL indicating the tested capacitor is shorted or it exceeds the
maximum range.
•
When capacitance measurement has been completed, disconnect the test leads
from the device under test.
