2620A, 2625A

Users Manual

∙Active Mode if this mode was in effect prior to the cycling of power. Scanning, monitoring, or combined scanning/monitoring is resumed.

∙Inactive Mode if the instrument was in Inactive Mode or Configuration Mode prior to cycling of power.

When in Inactive Mode, the instrument shows configuration information for the displayed channel. The channel number appears in the right display, and other annunciators are dimly lit to show the present setup for this channel. For example, if the channel is set up to measure ke, the "k" and "e" annunciators are dimly lit. Alternatively, if this channel has not been set up to measure anything, the "OFF" annunciator is lit dimly.

You can change the channel by pressing Gor D.

Front Panel Display

Full descriptions of the display annunciators are presented in Table 2-1.

Reading the Display

The instrument display uses both alphanumeric characters and fixed annunciators. When in Configuration Mode, these features are used to provide user prompting. In Inactive Mode, they provide status information. In Active Mode, they provide both status information and measurement data.

Information is presented on the display during both front panel control and computer interface control. If the instrument is being controlled through a computer interface, the display shows the results of computer-interface initiated actions (even if the front panel controls have been disabled.)

The remainder of Chapter 2 (as well as Chapter 3) relates to front panel control of the instrument. Refer to Chapter 4 for additional information about computer interface operation.

Left Display

The left display has five large numeric characters to show measurement results, "otc" when an open thermocouple is detected, or "OL" when a measurement is over range.

During Configuration Mode, the left display is also used to display the numeric values and instrument parameters being chosen.

Right Display

The right display has five small alphanumeric characters to show the channel number, display prompting information during setups, or to count down the scan interval.

Specific Annunciators

The rest of the display is devoted to specific annunciators, combinations of which are used to describe the operating mode, the type of measurement being displayed, or the type of setup information to be entered. These annunciators are described in Table 2-1 and shown in Figure 2-5.
