8. Blue Switch — Press the switch to toggle between AC Voltage / Current and DC Voltage / Current in the
Voltage / Current mode or to toggle between Resistance and continuity and diode in Ω/ /:
mode or to toggle between Frequency and RPM in Hz/RPM mode.
9. Hold Switch — This switch is used to hold the measured value for all functions, when pressed the “ “
annunciator is displayed. Conversions are made but the display is not updated.
This switch could be used in “MIN/MAX” mode or “PMIN/MAX” mode.

Hz Switch — This switch is used to quickly view the frequency during measuring the AC voltage or current.
Press “ % Hz “ switch once the LCD is changed to display frequency. Push “ % Hz “ switch
again, the LCD back to display the AC signal amplitude reading. In “ % Hz “ mode, pressing
RANGE key switch does not change the frequency range. However , the RANGE key switch
changes the sensitivity of frequency detection, if the input signal amplitude is less than 5% of
full scale range, the user shall increase the sensitivity. Pressing Range switch in “ % Hz “
mode also changes range of the original voltage or current mode.
