MD 9270 Leakage Clamp TRMS Meter with Power Function

Data Retention Mode

4. Data Retention Mode
To access the data retention mode we need to press the HOLD key; by pressing the
key repeatedly the HOLD, MAX and MIN modes can be selected. The three modes are
available in all the measuring functions except in the peak measurement.
HOLD Mode
In this mode, the average in the value shown on the screen when the key was pressed
is held. The symbol will also appear on the screen. In the harmonic measurement
function, pressing the HOLD key stores the information of all the harmonics. The
harmonics can then be scrolled through by pressing the HARM+ and HARM- keys.
MAX Mode
In this mode, the maximum measured value is shown on the screen. The symbol MAX
will be shown. Before using this function, the clamp should be connected correctly (see
section 3).
When recording the value, the difference between the peak value and the maximum
value should be taken into account: the maximum value holds the highest value of the
magnitude we are measuring on the screen, whilst the peak value shows the highest
absolute value of the waveform.
MIN Mode
In this mode, the minimum measured value is shown on the screen. The MIN symbol
will be shown. Before using this function, the clamp should be connected correctly (see
section 3)
