Configuration & Calibration

Level
and
Upper Level
values. Select an NPO
Capacitor (which can be NIST traceable, if desired
or required) that falls somewhere mid-range.
Example:
See Fig. 3-18.
If Lower Capacitance
is 50pF and Upper Capacitance is 2000pF, that
corresponds to a Lower Level and Upper Level of 0-
10 feet. Select an NPO Capacitor of approximately
1000pF. [Drexelbrook 401-6-8 Capacitor Substitute
Box may also be used; it is traceable to NIST].
C. Connect the NPO capacitor selected from the last
step to the
Probe
and
Ground
connections at
the transmitter (with coaxial cable from sensing
element disconnected).
D. Select
Real Time View
on the PC software Menu
Screen (F4 on your keyboard)
See Fig. 3-19
.
The display should show the Capacitance as the
value of the NPO Capacitor (within the capacitors
tolerance), and the
LEVEL
should display close to
the mid-range of the Lower and Upper Level from
the
Level Calibration
field. The
Loop Current
and the
Percentage
will also reflect the values
that are generated by the NPO Capacitor. Add to
the scratch pad of the Menu Screen the value of
the NPO capacitor that you used. If desired, this
information can be printed out for file or record
purposes. Mark or Tag this capacitor
*
to correspond
to this specific transmitter. Put the capacitor in
a safe location for use in subsequent testing and
validation.
E. By placing the same exact capacitor
*
on the RF
transmitter's
Probe
and
Ground
terminals and
observing the signal output generated by this
capacitor, it can be verified that the transmitter
is operating properly and that the calibration
information is the same as during the initial set up.

* Every capacitor
manufactured will generate a
slightly different capacitance value
within its specified tolerance. By
marking the capacitor and using
only this capacitor for testing and
validating the AMETEK Drexelbrook
RCT Series Transmitter, the system
should produce repeatable results
within transmitter specifications.
