OVERVIEW
SCAMP TM is an advanced electronic flowmeter signal conditioner that converts the
output signal from the flowmeter to a volumetric unit of measure. SCAMP also
temperature corrects the volume delivered to an API standard or to a programmable
coefficient of expansion, and has the ability to linearize the flowmeter accuracy at up to
sixteen points over its entire flow range. SCAMP is factory programmed and calibrated
to provide a volumetrically correct, Weights & Measures approved and sealed,
quadrature pulse output. The SCAMP output pulse can be used to operate most pulse
actuated electronic counters, flow computers, PLC’s or other electronic control devices.
SCAMP is micro-processor driven, and features a regulated power supply to protect
against voltage transients, easy-to-use binary coded decimal (BCD) switches for data
entry, watchdog timer to ensure reliable execution of software code, and a 7-segment
LED display for data verification and error messaging.
SCAMP is ready for operation with a minimum of mounting requirements and external
wiring connections as described in Steps 1 and 2 on the following page. After
installation but before final commissioning, the customer should verify that all factory-
programmed parameters are resident in SCAMP memory, and that all data agrees with
the values listed on the Meter Calibration Sheet included with the meter.
NOTE: It is important that the SCAMP circuit board be paired with the meter for which it
has been factory calibrated. Proper pairing of SCAMP and meter can be confirmed by
matching Serial Number data for the meter and SCAMP, as recorded on the Meter
Calibration Sheet. If the SCAMP circuit board is applied to a different meter, all
calibration data for the meter must be re-computed and entered into SCAMP as
described later in this manual.
HELPFUL HINT: Customer-entered data values are setup by first selecting one of the
basic SCAMP functions on the Function Switch (see Appendix B), and then setting the
numeric data for that function on the five Data Switches on the SCAMP circuit board.
Data is entered in memory by depressing the Data Entry pushbutton located on the
SCAMP circuit board to the right of the Function Switch (see diagram on following page).
Recovery from mis-entered or incorrect data is easy with SCAMP: simply re-position the
Data Switches to the proper settings, and depress the Data Entry pushbutton.
NOTE: On occasion, it may be desireable to clear all customer data from the SCAMP
non-volatile memory and re-enter new data. This can be accomplished by performing a
“Clear All” operation. To perform the “Clear All”, set the Function Switch to “0”, set all
Data Switches to “0”, move the “0/1” jumper to the “0” position, and the “LOCK” jumper
to the left-most position to unlock the unit, and then depress the Data Entry Pushbutton.
This procedure should only be utilized in special cases involving complete
reconfiguration of your unit. WARNING: After a successful “Clear All” operation, it
will be necessary to re-enter all calibration data. To minimize the re-calibration
effort, you may want to record all accessible data and Error Messages (Function
Switch position “E”) before performing the “Clear All”.
