ROUTe:MONitor:STATe {OFF | ON}
ROUTe:MONitor:STATe?
Enables (On) or disables (Off) the Monitor mode. The Monitor mode is equivalent to making continuous meas-
urements on a single channel with an infinite scan count. Only one channel can be monitored at a time but you can
change the channel being monitored at any time. This feature is useful for troubleshooting your system before a test
or for observing an important signal.
Parameter Typical return

Default: OFF
0 (OFF) or 1 (ON)
Configures specified channel for DC voltage measurements, enables monitoring on the channel, and turns on
the Monitor mode.

– Channels must be configured for a measurement in order to be monitored (see CONFigure and SENSe com-
mands). Configuring a channel for a measurement makes it monitorable and makes it part of the scan list.
– The Monitor mode is automatically enabled on all channels that are part of the active scan list (see ROUTe:SCAN
command).
– A scan always has priority over the Monitor function (see ROUTe:SCAN command).
– The Monitor mode ignores all trigger settings (see TRIGger:SOURce command) and takes continuous readings
on the selected channel using the IMMediate (continuous) source.
– Any channel that can be "read" by the instrument can be monitored. You can also monitor a digital input channel
or the totalizer count on the digital modules.
– Measurement scaling and alarm limits are applied to the selected channel during a Monitor and all alarm data is
stored in the alarm queue (which will be cleared if power fails).
– The count on a totalizer channel is not reset when it is being monitored (the Monitor ignores the totalizer reset
mode).
– Readings acquired during a Monitor are not stored in reading memory but they are displayed on the front panel;
however, all readings from a scan in progress at the same time are stored in reading memory.
– In DMM Digitize mode, no measurements are taken for monitor operations on the single channel configured for
digitizing while the instrument is in the "wait-for-trigger" state with pretrigger count is zero. However if the pre-
trigger count is not zero, there will be monitor data while the instrument is in the "wait-for-trigger" state.
– In DMM Digitize mode, monitor operations on the digital modules (DAQM907A) is not supported.
