5 Measurement Value Storage, “DATA Function”
(Hold & Compare)
Measurement values can be automatically “frozen” with the
DATA (hold) function. This can be especially useful when
your full attention is required for contacting the measuring
point with the test probes. After the measurement value
has been acquired and the appropriate “condition” as
shown in the table below has been fulfilled, the measure-
ment value is frozen at the digital display and an acoustic
signal is generated. The test probes can now be removed
from the measuring point and the measurement value can
be read from the digital display. If the measurement value is
less than the lower limit value shown in the table, the
instrument is reactivated and stores a new value.
Measurement Value Comparison (DATA Compare)
If the newly stored value deviates less than 100 digits from
the previous value, the acoustic signal sounds twice. If it
deviates more than 100 digits, only a brief acoustic signal
sounds.
1)
Reactivation if actual value falls below prescribed limit value
2)
Relative to alternating voltage values
3)
Acoustic signal sounds twice when measurement value is first
stored as reference value. Only sounds twice for subsequent hold
function if the current hold value deviates less than 100 digits
from the first hold value.
4)
Exception: 10% at 300 Ω or 3 nF
The DATA function has no effect on the analog display,
which continues to indicate the current measurement
value. However, as long the digital display remains
“frozen”, the decimal place can not be shifted.
The measuring ranges ought not to be changed manually
as long as the DATA function is active.
The DATA function is deactivated by pressing and holding
