Calibration 9
3.0 Calibration
Follow the procedure on the following pages for calibrating the UPC5200/UPC5210.
NOTES:
• When calibrating, the computer within the UPC5000/UPC5010 is actually being re-programmed, therefore it is
important that the pressure standard being used is in satisfactory operating condition and that the technician
fully understands its operating characteristics and methods of usage. In addition, the UPC5000/UPC5010 itself
must be properly warmed up (approximately 10 minutes) and electrically stabilized prior to performing a
calibration cycle.
• The Condec Repair Lab is equipped to do calibrations on Condec calibrators and pressure standards.
Calibrations include a certification and are traceable to N.I.S.T (see “UPC5200/UPC5210 Return Material
Authorization Form” on page 50).
3.1 Pneumatic Calibration Set-Up
A typical GAGE calibration set-up using a floating piston type dead weight tester is shown in Figure 3-1. While
doing an ABSOLUTE only unit calibration, a vacuum pump with a PSIA test standard is required where the dead
weight tester/pressure source is shown in Figure 3-1. This enables going below local barometric pressure.
NOTE: Any type of precision pressure or vacuum standard is acceptable as long as its basic accuracy is ±0.025% of
point or better.
To permit proper calibration, at least an ON/OFF and a VENT valve (connected as shown in Figure 3-1) must be
provided.
3.2 Instrument Calibration Set-Up
The UPC5200/UPC5210 is placed into its calibrate mode by connecting a Condec Calibration Module, PN
60109, via the multi-pin jack. The jack is located behind the small slide plate near the lower left corner of the
panel (see Figure 3-1).
The Condec Calibration Module, provides access to the calibrator's various program modes via a five-position
rotary switch. It also provides a means of entering and storing data via four other momentary action switches.
In the calibrate mode, the UPC5200/UPC5210's numerical display is used to provide operator prompting
symbols as well as displaying the various data formats employed. For example, in Figure 3-2, the data format
shown is obtained as soon as the ZERO/SPAN position of the rotary switch has been selected.
