Apply power to calibrator with AC adapter or charge battery.

Turn on power switch located in the top right corner. Power is on when green light illuminates - the pocket PC will ﬂash an orange light.

Push Pocket PC power button in top right of the unit. It will display a “start” screen. Tap “start” and select Setra Calibrator icon from “last

programs run” or “programs” ﬁle from drop down menu.

Calibrator starts in “Real Time” mode. Tap UUT (Unit Under Test) tab and select a stored UUT ID that corresponds to the pressure sensor

you wish to test - (tap the down arrow in the top box to view all of the stored UUT test proﬁles). Power is supplied to test pressure sensor

when UUT ID is selected. If a needed ID is not found, see Creating and Modifying UUT ID’s below.

Plug in pressure tubing and electrical cables into marked sockets on the top panel. Connect pressure tubing to “high” and “low” pressure

ﬁttings. Hook up connections as follows:

1. 4-20mA current loop operation, connect +EXC to red 869 banana jack and -EXC to black jack.

2. For 3-wire voltage output operation, connect +EXC to red electrical jack, -EXC common to black jack, and +Output to green

jack.

Return to “Real Time” screen to verify correct zero pressure output of test pressure sensor. Tap “tare” button to re-zero onboard pressure

references (approx 10 seconds). You can also check full-scale output by tapping “+FS” (+ full scale) button. You can also make zero and

span adjustments to test pressure sensor at this time.

Go to “Test” screen and tap “Do Test” button to initiate automatic calibration test. The calibrator will apply test pressures and record output

results until “test complete” ﬂag is displayed. You can save the test data by tapping the “Save Test Results” button. The data is saved with

Model 869 Quick Start Guide

To create a new UUT ID go to the UUT screen and tap “new” button. Next, type in a new UUT ID in the upper box. Enter data by tapping

the keyboard icon in lower right of screen. Characters are entered on screen at the cursor when mini-keyboard characters are tapped. An

existing ID template must be selected in “copy from” box. It is suggested that an existing ID template be chosen that closely matches the

pressure sensor desired to test either in pressure range or output type. Tap “ok”. When screen returns to UUT, any ID values can be modi-

ﬁed using keypad. Use dropdown boxes to change excitation, output type, or number of test points. Hit “save” button and new test proﬁle is

ready to use.

To modify a UUT ID, select desired UUT ID from dropdown screen, make changes, and tap “save”. The newly created or modiﬁed UUT IDs

will be available from dropdown UUT ID screen.

1.0 SAFETY INSTRUCTIONS Use the calibrator only as specified in the manual, otherwise the protection provided may be impaired. Do not operate the calibrator in explosive gas, vapor or dust environments. The calibrator is designed to operate from 14.4 VDC internal Lithium Ion battery source or from the AC adaptor that is included. Do not use AC adapters or chargers other than those supplied with the unit. If supplying external excitation to the Unit Under Test in a measure mode, do not exceed 30 VDC.

10.0 GLOSSARY OF TERMS Atmospheric Pressure - Pressure of the atmosphere at the Earth’s surface. NIST standard atmospheric pressure = 1.01325 bar. Burst Pressure - The mazimum pressure that may be applied to the positive pressure port without rupturing the sensing element. Capacitive Sensing - Detection and measurement of pressure through the change in voltage accross a capacitor, one plate of which is a diaphragm which deflects slightly with changes in applied pressure.

6.5 UUT (UNIT UNDER TEST) SETUP: General Screen Instructions (Diagram 13): UUT setup screeen is used for inputting UUT profiles into the UUT database. The calibrator is supplied with many default instrument templates which may be copied, modified and saved as new UUT. 1. Select an Existing Profile - Go to the UUT ID drop down box, click the down arrow and select your unit from the list. 2. Create a New Profile - Tap NEW button at bottom of page, a dialog box will appear prompting user to enter new UUT ID.
PAGE 21
Pocket PC Database - This list shows what test profiles are currently on the Pocket PC. After editing any profile, said profile will automatically download to the Pocket PC. This ensures that the list window always accurately reflects what is on the Pocket PC. (See Diagram 28) 11. Save - Once all parameters have been changed, tap the SAVE button at bottom. Note: Save button will be ‘grayed out’ when data has been saved. 12. Delete - Select UUT from list of available UUT ID’s at the top of the screen.

EDIT DEFAULTS PAGE Display trend graph on UUT warm-up box will make a graph appear when the DoTest Button is pressed on test page.The graph will show UUT output vs. time to allow the operator to see if the UUT has a warm-up drift, and output has been stabilized. (This feature is not likely to be required if the units to be tested are normally connected to a power supply.) Display test results in graph will make a graph appear at the end of the automated test.
