To Configure a Channel for Scanning

Chapter 1 Quick Start

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.

1Select 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.

2Select 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 timeout 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.
