To Monitor a Single Channel
You can use the Monitor function to continuously take readings on a single 
channel, even during a scan. This feature is useful for troubleshooting your system 
before a test or for watching an important signal. 
1 Select the channel to be monitored. 
Only one channel can be monitored at a time but you can change the channel 
being monitored at any time by turning the knob. 
2 Enable monitoring on the selected channel. 
Any channel that can be “read” by the instrument can be monitored (the MON 
annunciator turns on). This includes any combination of temperature, voltage, 
resistance, current, frequency, or period measurements on multiplexer 
channels. You can also monitor a digital input port or the totalizer count on the 
multifunction module. 
To disable monitoring, press   again.
