Comparator Menu Screen
The “Comparator” menu allows the selection of the available divider voltage
comparisons to a reference voltage and displays the current status of the
measurement configuration. On the display you will see the status of the
configuration indicated in green, signifying the active measurement configuration.
This operation mode is desirable when using decade values of voltage and
comparing them to a 10V reference standard.
When calibrating voltage sources, such as calibrators, the “Comparator” mode is
used.
You can touch the desired voltage button to engage the configuration. The line
will turn green and the Open button will turn white. You should always
disengage a configuration before engaging a new configuration. Selecting the
“Open” button disengage all measurement configurations and return the active
green highlighted range back to white.
WARNING: NEVER CHANGE OR ENGAGE A VOTAGE COMPARATOR
