Fuses
Fuse for upto 300mA ranges

Fast blowing 1.6 A / 500V; 6.3mm X 32mm; rating 20kA with
500V

and ohmic load; in conjuction with power diodes, protects

all current measuring ranges upto 300mA.

Fuse for upto 10A ranges

16 A / 600V; 10mm x 38mm; rating 100 kA with 600V

and

ohmic load; protects the 3A and 10A ranges upto 600V; see
"18. maintenance" for manufacturers and types of fuses.

divisions so that variations of the measured values around "zero"can be
observed exactly. When the measured value exceeds the range of
indication, the left triangle (16) is shown before the polarity of the analog
indicator switches over after approximately 0.7s. The over range indication
on the measuring range (>3099 digits, on the range

>1999) is shown

by the right triangle (13).

6. ’’DATA’’hold facility

The DATA function allows to automatically hold the measured values.
This is particularly useful, for instance, when connecting the probes to
the measuring point requires full attention. When the measured value is
applied and the ’’condition’’ according to the table shown below is met,
the meter holds the measured value on the digital display and emits a
sound signal. The probes can now be removed from the measuring point
and the measured value on the digital display (9) can be read. When the
measured value falls below the limit specied in the table, the meter is
reactivated for a new storage.
The analog indication is not inuenced by the DATA

hold, The actual

measured value can still be noted / read. Note that with a held digital
display, the location of the decimal point is also held. With autoranging
selected, the measuring range of the analog indicator is no longer known.

As long as the DATA hold function is active, manual range selection is
not possible. The DATA hold function is switched OFF, when,

The "DATA” pushb utton (3)

is pressed for approx. 1s. This is

acknowledged by 2 sound signals.
The function selector switch (6) is operated or
The multimeter is turned OFF and ON again.

Minimum value and Maximum value ’’MIN/MAX" storage facility.

With the MIN/MAX function, you can hold the minimum and the maximum
measured value which was applied to the input of the multimeter after
activating MIN/MAX function. The most important application is the
determination of the minimum and the maximum value for long-term
monitoring of measured quantities. MIN/MAX does not inuence the
analog indication The actual measured value can still be noted/read.
Apply the measured quantity to the meter and select the measuring
range prior to activating the MIN/MAX function.
With the function activated, you can select the measuring ranges only
manually, if you switch to another range, the stored MIN/MAX values are
cleared.
