Users Manual

Other Displayed Data

An array of "MIN", "MAX", and "LAST" values for each channel is updated whenever scan measurements are taken. This Review array can be displayed from Active or Inactive (but not Configuration) Mode by pressing N.

The constantly updated Totalizer count can also be displayed (Active or Inactive Mode only) by pressing O.

Note that either the Review array or the Totalizer count can be displayed at one time; you must deactivate one before activating the other. Deactivate the Review array by pressing Na second time. Deactivate the Totalizer display by pressing Oa second time. Pressing Calso deactivates either function.

What is the Present Configuration?

If Power is Interrupted

All configuration settings (function, range, scan interval, etc.) are stored in nonvolatile memory. If power is interrupted (Rpressed off or due to power loss), these settings are retained. When turned on, the instrument first executes a self test, then resumes the state it was in prior to interruption of power. This feature is handy for applications where power may be inadvertently lost; the instrument automatically resumes taking measurements, as originally configured, once power is restored.

If the Configuration is Reset

You can perform a Configuration Reset in either of two ways:

∙From the front panel, press and hold lwhen cycling POWER ON.

∙Through the computer interface, send the *RST command.

Refer to Table 3-1 for the configuration reset settings.

Channel Configuration

Configuration Mode involves selecting an entry from a list of choices (and may involve setting number values.) Measurements are not taken when the instrument is in Configuration Mode. Configuration Mode is discussed throughout this chapter; it is used whenever a parameter for a channel or for the whole instrument needs to be set.

Selecting Channel, Function, and Range

Steps necessary for setting each type of measurement function are shown in the following tables:

∙DC Voltage Measurement (Table 3-2)

∙AC Voltage Measurement (Table 3-2)

∙Resistance Measurement (Table 3-3)

∙Frequency Measurement (Table 3-4)

∙Temperature Measurement Using Thermocouples (Table 3-5)

∙Temperature Measurement Using RTDs (Table 3-6)

Additional channel configuration steps (alarms, scaling, etc) are discussed later in this chapter.
