MS8218 True RMS Multimeter
Operation Methods
Linear Frequency Measurement
The measurement is seen in the Figures 3-1, 3-2, 3-3,3-8 and 3-9. The measurement range is of 5Hz
～
200KHz and the
measurement methods are as follows:
1. When performing voltage or current measurement, in case of measured value being AC or including AC elements, it is
possible to measure and display the alternating frequency by pressing the
～
～～
～
Hz key. However it has a certain
requirements for the amplitude of alternating signal and the meter has varied requirements for signal amplitude when it is
in different ranges, for information of which please refer to Table 3
—
1.
2. If the position of rotary switch is in ACV or DCV, after pressing
～
～～
～
Hz key the indicator of range will indicates the
meter’s present voltage range. In addition, it is possible to change the range by pressing the RANGE key to meet the
different voltages.
3. Press
～
～～
～
Hz key again to exit linear frequency

Notes: During ampere measurement, due to the very small sample resistor, and the very weak frequency signal produced, so
only when current reaching as large as over 5A can the frequency be measured.
