5 Measured Value Storage – DATA / MIN-MAX Key
5.1 DATA (hold / compare)
Measured values can be automatically frozen at the display with the DATA (hold)
function. This is especially useful when full attention is required for contacting the
measuring point. After the measured value has been applied to the multimeter
and the “condition” indicated in the following table has been fulfilled, the mea-
sured value is frozen at the digital display and an acoustic signal is generated.
The test probes can then be removed from the measuring point, and the mea-
sured value can be read from the digital display. If the measured value is less
than the limit value shown in the table, the instrument is reactivated for a new
measurement with the DATA hold function.
If the new measured value deviates from the previous value by less than 100 dig-
its, the acoustic signal sounds twice (DATA compare).
1)
Reactivation occurs if the indicated measured value limits are fallen short of.
2)
Double acoustic signal after the first measured value has been stored.
Thereafter, double acoustic signal only occurs if the currently frozen value deviates from the
first stored value by less than 100 digits.
3)
Exception: 10% at 300 
Key: MR = measuring range
The DATA function has no effect on the analog display, which continues to
indicate the current measured value. However, it must be observed that the
decimal place is fixed when the digital display is “frozen”.
The DATA function can be deactivated by pressing and holding the DATA key for
about 1 second, by turning the function selector switch or by switching the
instrument off and back on again.
