1
Connect the terminals as shown in the figure above.
2
Use the FUNCTION key on the MEASURE side to align
the
measurement mark with FREQ. (Frequency and pulse selection)
3
Use the RANGE key to select a range. Set the range in accordance with
the object to be measured.
<For frequency measurement>
Set the range to 100 Hz, 1000 Hz, or 10 kHz.
The measurement value and unit (Hz or kHz) appear.
<For pulse measurement>
Set the range to 100000 CPM or 100000 CPH.
After the measurement value is reset to 0, the unit (CPM or CPH)
and HOLD are displayed. The instrument is in a standby state for
measurement.
4
Press the HOLD key to start pulse count (measurement).
In the CPM range, pulses are counted (measured) for 1 minute. In the
CPH range, pulses are counted (measured) for 1 hour. (HOLD lights
up.)
Tip
• In the case of the CPM and CPH ranges, pressing the HOLD key while HOLD is lit
after the count ends will restart the count from 0.
• In the case of the CPM and CPH ranges, pressing the HOLD key partway through
before the selected time (CPM: 1 minute, CPH: 1 hour) is reached will end
the count at that point in time. (The count value until the end is displayed.)
• In the case of the CPM and CPH ranges, “------” is displayed and measurement
ends if the count number exceeds the measurement range (limit).
• Auto power off does not work while the 100000 CPH range is selected.
