Frequency Measurements 1) 2) 3) 4) Ensure that at least 0.1A AC is detectable with an ACA measurement before measuring Frequency. Set the Function switch to the Hz position. Press the Trigger to open the Jaw and fully enclose the conductor to be measured. If line frequency is being measured, enclose only one line of the source (ensure first that there is current present). Read the Frequency measurement on the LCD in Hz.
