HVM100 User Manual

•

The HVM100 indicates when an overload is currently
occurring on any of the three inputs. The HVM100
flashes the following screen.

•

The HVM100 uses an * to indicate that an overload has
occurred since the last reset. The * is displayed on all
channels regardless of which channel was overloaded.
The Amp value on the overload channel will display
“OVER”

•

Short Term values like Arms, Peak, Time History values
etc. will be reported as OVER whenever an overload cor-
rupts these values.

Under-Range Indicator (?)

The under-range indicator will replace the bar graph run
indicator whenever the channel currently displayed is under-
range. The under-range indicator, like the bar graph, is inde-
pendent for all three channels. A channel is under range
whenever the input rms signal level is below the minimum
RMS Range level as specified in the Typical Measurement
Range tables in Appendix A. For example, with 0 dB gain, if
the input rms level drops below 74 dB

µ

V (5 mV), the under-

range indicator will be displayed

.

Run-Interrupted Indicator (!)

If the HVM100 is stopped and then run again without reset-
ting the current data, the run-interrupted indicator (!) will
replace the colon (:) in all displays that show the run time.
The “!” indicates that the data in the HVM100 is not contig-
