Freezing A Measured Value - Monacor ZM-100 Mode D'emploi

5.2 Freezing a measured value

GB
Press the button HOLD (8) to freeze the reading. "H" (1) will be dis-
played. To return to the present value measured, press the button once
again; the "H" will disappear. This function is only available with auto-
matic range selection ["Auto" (2) will be displayed)]. With manual range
selection, the button HOLD has a different function (see chapter 5.3).
5.3 Measurement in a noisy environment
External sound in a noisy environment may interfere with the measure-
ment, indicated e. g. by a constant change of the reading. To minimize
the effects of ambient noise on the measuring result, the ZM-100 is pro-
vided with a function for calculating the average value over a given
time. This function can be called as follows:
1) Manually select the smallest possible measuring range with the
button RANGE (7). (With a measuring range which is too high,
the meas urement will not only be less accurate, the disturbance of
the measurement by ambient noise will also be substantially in -
creas ed.)
2) Press the button HOLD (8). "H" (1) will be displayed; this will start
the function for measuring the average value.
3) Measure for a minimum of 20 seconds before reading the value; the
longer the measurement, the more accurate the result.
4) To terminate the calculation of the average value and to return to the
present reading, press the button HOLD once again; the "H" will dis-
appear.
