MIN / MAX HOLD USAGE
See the
SPECIFICATIONS
section for response time information.
The MAX HOLD function holds the reading that is arithmetically greater than all previous readings. The MIN HOLD function holds the reading
that is arithmetically less than all previous readings. These modes are useful in determining the maximum or minimum value of magnetic
events that occur over a period of time.
If the reading exceeds the range limit, the 5280 meter will hold a flashing value of “2999” (gauss or tesla mode), “2387” (ampere meter mode)
or the maximum value allowed in the RELATIVE mode. The 5270 meter will hold a flashing value of "1999" (gauss or tesla mode), "1592"
(ampere meter mode) or the maximum value allowed in the RELATIVE mode.
The held value can be reset by pressing the RESET button. The next value displayed after a reset will be the present value of flux density.
For instance, if the held reading is 200.0 G and the present flux density is 100.0 G, the meter will display 100.0 G after the reset.
If the analog output is being used, the output signal will continue to represent the real time flux density as seen by the probe. It is not affected
by the HOLD function.
PEAK HOLD USAGE
See the
SPECIFICATIONS
section for response time and accuracy information.
In the PEAK HOLD mode, the input signal is sampled many times each second. Each sample is compared to all previous samples and that
which has the greatest amplitude (regardless of polarity) is held on the display. This mode can be used to capture the peak value of a fast,
onetime magnetic event such as a magnetizing pulse.
These are the differences between the PEAK HOLD mode and the MIN / MAX HOLD modes:
The PEAK HOLD mode considers the magnitude of the reading regardless of the polarity.
The response time of the PEAK HOLD mode is much faster but final accuracy is less.
If the analog output is being used, the output signal will continue to represent the real time flux density as seen by the probe. It is not affected
by the HOLD function.
