3.3 Quick Measurements
If you wish to perform quicker measurements than those pos-
sible with the automatic measuring range selection function,
make sure to establish the appropriate measuring range:
•by manual measuring range selection, i. e. by selecting the
measuring range with the best resolution, see
chapter 3.2.
or
•via DATA function, see chapter 5. After the first measure-
ment, the proper measuring range will be automatically
determined so that measurements are performed more
rapidly from the second measured value onwards.
With both functions, the established measuring range is
maintained for the subsequent series mode measurments.
4 Triple Digital Display
The three digital displays (1 main display and 2 auxiliary
displays) show the measured value with decimal and plus or
minus sign. The selected unit of measure is displayed as well.
A minus sign appears to the left of the value during the
measurement of zero-frequency quantities, if the plus pole of
the measured quantity is applied to the “” input.
“OL” (overload) appears if the measuring range upper limit is
exceeded for the following measured quantities:
V AC, V DC, Hz, ,
, m, 30 / 300 m at 1 A: 30999
3 m at 1 A, , M
@...V: 3099
The digital display is refreshed at different frequencies for the
various measured quantities.
The main display appears immediately after the multimeter is
switched on, but the auxiliary displays have to be activated by
pressing the DATA|CLEAR key (except for position M@...V,
where the auxiliary displays appear immediately upon
selecting the function).
This assures that any undefined existing condition which
prevailed when measurement was started is not continuously
displayed as a maximum value, e.g. no-load operation.
In the following flowcharts, the initial displays are highlighted
through the use of a bold border line.
