Line frequency

On power-up, the Model 2182 detects the line power frequency and automatically selects the

proper line frequency setting. The line frequency setting can be checked using the following

command:

:SYSTem:LFRequency?

The response message will be 50 or 60. The value 50 indicates that the line frequency is set

for 50Hz (or 400Hz), while 60 indicates that it is set for 60Hz.

Display

The display of the Model 2182 is primarily used to display readings, along with the units and

type of measurement. Annunciators are located at the top, bottom, left, and right of the reading

or display message. The annunciators indicate various states of operation. See “Front panel sum-

mary” (presented earlier in this section) for a complete listing of display annunciators.

NOTE The Display and Keys Test allows you to test display digit segments and annunciators,

and check the functionality of front panel keys. These tests are accessed by pressing

SHIFT and then TEST. Refer to the Model 2182 Service Manual for details.

Status and error messages

Status and error messages are displayed momentarily. During operation and programming,

you will encounter a number of front panel messages. Typical messages are either of status or

error variety, as listed in Appendix B.

Default settings

There are two default setup conﬁgurations; factory and user. As shipped from the factory, the

Model 2182 powers up to the factory default settings listed in Table 1-2. The Model 2182 can

instead be set to power up to a user default setup. The power-on default setup will be the last

conﬁguration you saved. The SAVE key saves the present conﬁguration as the USER power-on

setup. The RESTR key restores the instrument to the factory defaults or the user-saved defaults.

Perform the following steps to save the present setup as the power-on default conﬁguration:

1. Conﬁgure the instrument for your measurement application.

2. Press SAVE.

3. Use the  and  keys to display YES or NO.

4. Press ENTER. The instrument will power-on to this USER default setup.

NOTE To assure that the proper ﬁlter state is recalled, set the analog and digital ﬁlters before

saving the user setup. See Section 3.
