External Scan Quick Setup
The External Scan Quick Setup helps you set up the instrument to communicate with an external
switch system.
This Quick Setup does not reset the instrument, so before running it, make sure all function settings
are configured as needed for the measurements that will be made.
When you run this Quick Setup, the instrument:
•
Clears the reading buffer
•
Prompts you for the type of in and out lines (digital I/O or external I/O)
•
Prompts you for the number of channels in a scan
•
Prompts you for the number readings per channel
•
Prompts you for the function that will be run for each channel
Using this information, the instrument sets up configuration lists and the I/O lines for use with the
switch system.
A trigger out from the instrument notifies the switch system to control the scan channels.
A trigger in from the switch system indicates that the switch is ready and the instrument can make
measurements.
Auto Delay
Auto Delay applies a wait period at the end of a function change, range change, and other
measure-related settings. The delay allows cables or internal DMM circuitry to settle for best
measurement accuracy. For the AC current and AC volts functions, the autodelay includes both the
RMS filter and AC-coupling capacitor-settling times.
•
When autodelay is disabled, no wait time is applied.
•
When autodelay is enabled, a measurement is not made until immediately after the autodelay
period has expired. Depending on the length of the required delay, there may or may not be an
impact on the first reading after a function or range change.
Autodelay times for each function are provided in the following topics.
To set autodelay from the front panel for the selected function:
1. Press the
MENU
key.
2. Select Measure
Settings
.
3. Next to Auto Delay, select
On
to include a delay or
Off
to remove the delay.
