Chapter 1 Quick Start

To Configure a Channel for Scanning

Any channel that can be “read” by the instrument can also be included in

a scan. This includes readings on multiplexer channels, a read of a

digital port, or a read of the count on a totalizer channel. Automated

scanning is not allowed with the RF multiplexer, matrix, actuator,

digital output, or voltage output (DAC) modules.

1 Select the channel to be added to the scan list.

Turn the knob until the desired channel is shown on the right side of

front-panel display. The channel number is a three-digit number; the

left-most digit represents the slot number (100, 200, or 300) and the two

digits on the right indicate the channel number (102, 110, etc.).

Note: You can use and to skip to the beginning of the previous or

next slot.

For this example, assume that you have the 34901A multiplexer

installed in slot 100 and select channel 103.

2 Select the measurement parameters for the selected channel.

Use the knob to scroll through the measurement choices on each level of

the menu. When you press to make your selection, the menu

automatically guides you through all relevant choices to configure a

measurement on the selected function. When you have finished

configuring the parameters, you are automatically exited from the menu.

The current selection (or default) is displayed in full bright for easy

identification. When you make a different selection, the new choice is

shown in full bright and it becomes the default selection. The order of the

choices always remains the same; however, you always enter the menu

at the current (full bright) setting for each parameter.

Note: The menu will time-out after about 20 seconds of inactivity and any

changes made previously will take effect.

For this example, configure channel 103 to measure a J-type

thermocouple with 0.1 °C of display resolution.
