Overload detector
The instrument has the built-in overload detectors. Both A/D converter and input amplifier overload conditions
are detected. The overload in the measurement channel (in its analogue part) and the overload of the
analogue / digital converter are both detect
ed. The “overload” indication appears when the input signal
amplitude is 0.5
dB above the declared “Peak measurement range”. This condition is checked once per second
or with the Logger Step if it is less than 1 second.
An overload is indicating by the flashing icon which is displayed during the period from the overload
detection till the end of the Integration Period. If the overload disappears to the Integration Period end, the
overload icon will not be displayed from the start of the next measurement cycle.
When an overload is detected, the special marker will be recorded to the logger file with the data logging step.
The overload time is measured by the OVL result during the Integration Period and is saved in the logger file
as part of Summary Results.
Underrange detector
The instrument has the built-
in underrange detector. The “underrange” indication appears when the RMS value
for the elapsed time is below the lower linear operating range. This is checked once per second.
An underrange is indicating by the flashing icon which is displayed during the period of the underrange
detection. When an underrange is detected till the Integration Period, the special marker will be recorded to
the logger file with the Integration Period step. If during the Integration Period the signal level increases and
the total RMS is greater than the minimum, the icon stops displaying and the underrange marker is not
recording.
