Setting the Measurement Rate

Perform the procedure in Figure 2-12 to set a fast or slow [default] measurement rate. The measurement rate affects the time required to scan the configured channels. However, the fast mode sacrifices one digit of measurement resolution. For example, a temperature reading of 22.4ºC in the slow mode would become 22ºC in the fast mode, or 27.858V dc in the slow mode would become 27.86 V dc in the fast mode. The fast mode is normally used to capture rapidly changing measurements or to speed up the measurement portion of the scan interval.

Setting the Alarms

Perform the procedure in Figure 2-13 to set alarm limits for any configured channel. In preparation, the instrument must be in the inactive mode (not scanning or monitoring) and the desired channel must be configured with a measurement function (see Figures 2-

4to 2-9) and selected (see Figure 2-3). To exit at any time, press the Ckey; however, any alarm parameters previously entered will remain. Two alarm limits, alarm 1 and alarm 2, can be defined for each channel. If applied to a channel with Mx+B scaling, the alarm is based on the scaled values. An alarm occurs when the measured value on the channel moves above the HI (High) or below the LO (Low) value. Alarms can start autoprinting (Figure 5-3), start scanning with the Monitor-Alarm trigger option (Figure 2-19), or trigger other functions via the rear panel digital outputs. In the inactive mode, any selected channel that is programmed with alarm limits will display LIMIT plus 1 and/or 2 to show which alarms have been set. In the different operating modes, the front panel will provide an indication of a channel in an alarm condition. Each is discussed below.

Alarm Indications While Scanning

If a scanned channel is in an alarm condition during the scan, the ALARM annunciator is turned on (dim display). If all alarm conditions clear during the next scan, the ALARM annunciator is turned off. See Figure 2-15 for information about the Scan Mode.
