To select from these choices:

TRIGS(KJ)]

OFF

ALAr

Note: The three trigger types signify:

"OFF" External triggering is disabled. Scan trigger is controlled by scan interval.

"ON" External triggering is enabled. A low input on the rear-panel TR terminal affects scanning as follows:

If the instrument is in Inactive Mode, or just the Monitor Function is on, the low input enables scanning. When the signal on the TR terminal returns to high, scanning is disabled.

If scanning is already enabled, the external trigger initiates a single scan. If a scan is already in progress, this request is ignored.

"ALAr" An alarm condition on the monitor channel automatically triggers a scan. (External triggering is disabled.)

External Triggering

The external trigger setting offers additional control of scan starts through a separate trigger line on the rear panel. Refer to Chapter 5 for an in-depth discussion of external triggering.

Changing the Temperature Unit

The displayed temperature unit can be degrees Celsius (ºC) or Fahrenheit (ºF). To switch this setting, start with the instrument powered off, then press and hold Bwhile pressing POWER ON. After the instrument beeps and the new temperature unit is shown in the display, release B.

The units setting can also be changed through the Computer Interface with the TEMP_CONFIG command (refer to Chapter 4.)
