Information:
                                    The Fluke Model 22 40 C Data Logger in its basic form is a
processor and recorder which, through the use of optional
plug-in modules, is expandable into a user-designed data
acquisition system capable of servicing up to 1000 channels
of guarded analog data. The basic unit is contained within a
mechanical housing and consists of a front-mounted control
panel, a digital display, a digital printer, a power supply,
the control logic required to interface the basic unit with
a full complement of options, an A/D converter and guard
crossing, and a series of pcb and module slots designed to
accommodate a number of plug-in options. To form an
operational data acquisition system, the 22 40 C must be
equipped with at least one each of the two following
options: a scanner (Option -05 , -06 or -33) and a scanner
input connector (Option -03, -07 or -08).
1-3· Front Panel
1-4. The front panel of the 22 40 C features al1 of the
controls necessary to operate the unit with a full
complement of options. The controls consist pr imarily of
pushbutton switches which are separated into 10 unique
groups. Five groups perf orm control functions and five
groups are dedicated to programming the 22 40 C„ The control
group includes: Power, OUTPUT CONTROL, PROGRAM LIST, SCAN
CONTROL, and DISPLAY CONTROL. The program groups include:
TIME ENTRY, SCAN FORMAT, PROGRAMMING (CHANNEL , AVERAGING,
mx + b, and LIMITS), ADVANCE ADDRESS, and DATA ENTRY.
1-5. The 2240C is energized when the power switch is set to
POWER ON or KEYBOARD PROGRAM DISABLE. In the POWER ON
position, all control functions are enabled. In KEYBOARD
PROGRAM DISABLE, all control functions except OUTPUT CONTROL
and SCAN CONTROL are enabled. If channel programming data
has been previously entered into memory (via the front panel
programming switches), any one of four unique scan modes
(single, in terv al, monitor, or continuous) can be started
and/or stopped using the SCAN CONTROL switches. During a
scan sequence, analog data present at program-selected
channe1s is measur ed and displayed at the 22 40 C front
panel. When desired, this measurement data can also be
recorded on either the internal pri nter and/or an external
recording device. The recording devices to be used and the
type of data to be recorded are selected by the OUTPUT
CONTROL and the SCAN CONTROL switch groups. While
measurement data is being recorded, alternate forms of data
(date and time or single channels) can be selected and
displayed by depressing the appropriate switches in the
DISPLAY C0NTR OL group. Similarly, an alternate form of
data, program list, can be recorded when the SCAN CONTR OL
switches are reset and the internal printer is ena bled to
print al 1 data. When the PROGRAM LIST switch is depressed
under these conditions, the contents of the
keyboardcontrolled program memory are recorded on the
internal printer» If a Remote Program Option (-15 or -17) is
installed, a program list can be requested and output via
the option.
