Operation 13
2.7 UPS3000 or UPS3210 Initial Setup Sequence
For UPS3000, refer to Figure 2-1 on page 5 and Figure 2-4 on page 6.
For UPS3210, refer to Figure 2-3 on page 6 and Figure 2-6 on page 8.
1. Connect the pressure source to the instrument via the
INPUT PRESSURE
port (16), 7/16-20, 37
o
-4 AN male
fitting provided on the rear panel. It is suggested that a Cheat Seal, PN 54854, be used between
INPUT
PRESSURE
port and pressure source fitting.
NOTE: Valves for venting and pressure input should be installed in line with the pressure source.
2. Apply power to the instrument using AC Cord (17) or, if applicable, by pressing
POWER
switch (13) on
front panel and allow it to stabilize for at least 5 to 10 minutes.
3. Select the desired full scale pressure range via the three-position rotary
RANGE SELECT
switch (6). For
the best accuracy, the selected range must be greater than, but close as possible to, the full scale range of
the Device-Under-Test.
NOTE : Do not switch pressure ranges during a pressure cycle.
4. If applicable or required, select the mode of operation by momentarily depressing the
ABS/GAGE
push-button switch (2). The applicable “ABS” or “GAGE” light bar (4) will be lit to provide mode of
operation.
5. To select the desired measurement display units, depress
CONV
push-button switch (3).
NOTE: When the PEAK HOLD or MAX/MIN option is supplied with a model having the ABS or GAGE mode, switch
selectable from front panel, the “ CONV ” button will be disabled and will not be present on the front panel. Refer to
Section 2.6 on page 12.
6. If operating the unit in
GAGE
mode go to Section 2.7.1 or if operating the unit in ABS mode go to
Section 2.7.2.
Application of pressures greater than 1.5 times the highest pressure range of the indicator may cause
calibration errors or even permanent damage to the pressure transducer.
2.7.1 UPS3000 or UPS3210 Display of Pressure Sequence GAGE Mode
1. Vent the Input Pressure port (16) to atmosphere.
2. Momentarily depress the
ZERO
push-button switch (1). The display will indicate
0.00
.
3. The instrument is now fully configured and ready to display the applied pressure.
2.7.2 UPS3000 or UPS3210 Display of Pressure Sequence Absolute (ABS) Mode
NOTE: If local barometric pressure is not 14.7, ABS/GAGE switch selectable units only, may need barometric offset. See
“Barometric Offset - Absolute/Gage Switch Selectable Units ONLY” on page 23.
1. If only pressure measurements greater than barometric are required, continue to Step 1.1. If pressure
measurements above and below atmospheric pressure are required go to step 2.
1.1. To apply pressure, close the customer supplied vent valve attached in line with the
INPUT PRESSURE
port
(16). Unit will display applied pressure.
2. If pressure measurements above and below atmospheric pressure are required, connect a VACUUM
PUMP in line with the
INPUT PRESSURE
port (16).
3. Close the customer supplied vent and input valve attached in line with the
INPUT PRESSURE
port (16).
4. Apply power to the vacuum pump and allow it to evacuate the system for several minutes or until the
digital display reading reaches equilibrium near Zero psia. Momentarily press the
ZERO
push-button
switch (1) to establish a zero reference on the display.
5. The instrument is now fully configured and ready to display the applied pressure.
