PEAk-rms Hold
�
(see figure 2)
Peak-rms captures and displays the maximum RMS value of surge voltage or current with
durations as short as 65ms when in Vac or Aac.
Press and hold Peak-rms button for 2 beeps to enter this mode.
The lCD annuciators ‘P-‘ & ‘Max’ are turned on.
Press and hold Peak-rms button for 2 beeps to exit this mode.
HoLD
�
(Data Hold)
freezes the reading present on the lCD at the moment the button is pressed.
Set up the meter for the type of measurement desired.
Connect the test leads or clamp jaws to the circuit/component to be measured.
Press hold button.
The lCD reading will freeze and display ‘
�
‘. You may now remove the test leads and the
reading will not change until you press the hold button again
�
Caution
Connection to a Hazardous Live circuit will still display the previous reading. this
function will not update the reading.
tHD%-f (total Harmonic Distortion-fundamental) (see figure 3)
fundamental distortion is the percentage ratio of the Total harmonics RMS value to the
fundamental RMS value of a voltage or current signal.
ThD%-f = (Total harmonics RMS / fundamental RMS) x 100%
An ideal sinusoidal waveform has a value of 0.00 ThD%. A highly distorted sinusoidal
waveform may have higher ThD% value, up to several hundred.
Note:
Used with Vac or Aac, ThD%-f displays values up to 99 ThD% in the secondary mini
display. Press ThD%-f button to move ThD%-f readings to main display to show readings
up to 999.9 ThD%. Pressing ThD%-f button will alternate the reading location.
SELECt / backlight (

)
Press Backlight button more than 1 second, enable/disable Backlight.
Press the SeleCT / Backlight button to step through the manually selected V-A Auto

frequency (see figure 4)
Displays the line frequency when in Vac or Aac. Trigger levels vary with the ranges.
Press the ‘hz’ button to display the signal frequency.
Press the ‘hz’ again to return to previous display.
Auto Power off function
The clamp meter powers down automatically after approximately 17 minutes of inactivity.
To turn it back on, move the function selector switch to off and back to a measuring
function.
To disable Auto Power off, press and hold the holD button while moving the slide switch
