Installation Precautions

4 Read these instructions before using the gauge. Configuration

may be easier before installation. Contact the factory for assistance.

4 These products do not contain user-serviceable parts. Contact

us for repairs, service, or refurbishment.

4 Gauges must be operated within specified ambient temperature

ranges.

4 Outdoor or wash down applications require a NEMA 4X gauge or

installation in a NEMA 4X housing.

4 Use a pressure or vacuum range appropriate for the application.

4 Use fittings appropriate for the pressure range of the gauge.

4 Due to the hardness of 316 stainless steel, it is recommended

that a thread sealant be used to ensure leak-free operation.

4 For contaminated media use an appropriate screen or filter to

keep debris out of gauge port.

4 Remove system pressures before removing or installing gauge.

4 Install or remove gauge using a wrench on the hex fitting only.

Do not attempt to turn gauge by forcing the housing.

4 Good design practice dictates that positive displacement liquid

pumps include protection devices to prevent sensor damage from pressure spikes, acceleration head, and vacuum extremes.

p Avoid permanent sensor damage! Do not apply vacuum to non-

vacuum gauges or hydraulic vacuum to any gauges.

p Avoid permanent sensor damage! NEVER insert objects into

gauge port or blow out with compressed air.

 Gauges are not for oxygen service. Accidental rupture of sensor

diaphragm may cause silicone oil inside sensor to react with oxygen.

Cecomp maintains a constant effort to upgrade and improve its products. Specifications are subject to change without notice. See cecomp.com for latest product information. Consult factory for your specific requirements.

WARNING: This product can expose you to chemicals including nickel and chromium, which are known to the State of California to cause cancer or birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov

Types of Gauges

Bipolar ranges read positive pressure and vacuum in the same units, and zero with the gauge port open.

1000 psi and higher sensor are a sealed reference type. They read zero with the gauge port open are internally referenced to 14.7 psi. Functionally similar to gauge reference sensors.

Absolute reference gauges read zero at full vacuum and atmospheric pressure with the gauge port open. With an open gauge port the readings will vary continuously due to the effects of barometric pressure.

Selectable Ranges

Range Codes

The range code is part of the gauge model number and indicates the default range when the gauge is ordered.

Selectable Ranges

Engineering units may be changed to any of those listed in the same sensor range as shown in the range table.

Conversion

Engineering units are calculated from the factory default unit to the newly selected units. The ranges listed under the psi sensor range

are rounded off.

Operation

Power-Up

Press and hold the front button for approximately 1 second. The display is tested, the default full-scale range is indicated, the

full-scale range in the selected units are indicated, the display is tested again, then the actual pressure and units are displayed.

Power-Up With Zero

This applies to gauge reference models only. Absolute reference gauges do not use the zero feature since they read atmospheric pressure under normal conditions.

Be sure the gauge port is exposed to normal atmospheric pressure and no pressure is applied. The zeroing function is only activated at each power-up and the stored zero correction is erased when the gauge is shut off. Press and hold the front button. The display is tested and then oooo is displayed. The gauge is now zeroed. Release the button and the full-scale range in the selected units are indicated, the display is tested again, then the actual pressure and units are displayed.

Attempting to zero the gauge with pressure greater than approximately 3% of full-scale pressure or vacuum applied will result in an error condition, and the display will alternately indicate Err 0 and the actual measured pressure. The gauge must be powered down to reset the error condition.

Normal Operation

Following the start-up initialization, the display indicates the pressure reading updated approximately 3 times per second. The auto shutoff timer starts when the gauge is powered up or whenever the button is pushed, unless the gauge shutoff time was set to zero for on/off operation.

If excessive vacuum is applied to a pressure-only gauge, the display will indicate -Err until the vacuum is released. Applying vacuum to a gauge designed for pressure may damage the pressure sensor.

If excessive pressure is applied (112.5% over range), an out-ofrange indication of 1 – – – or 1.–.–.– will be displayed depending on model.

Display Backlighting (BL models only) Display backlighting can be turned on by momentarily pressing the front button whenever the gauge is on. The backlighting will turn on for one minute and then automatically shut off. This also restarts the auto shutoff timer. The display backlighting will not be apparent under bright lighting conditions.

Minimum and Maximum Readings

Gauges are normally configured with minimum and maximum capture functions enabled. One or both can be disabled in the Advanced Configuration mode.

Minimum and maximum readings are continuously stored and updated whenever the gauge is on. The stored readings can be manually cleared if desired. The MAX and MIN memory is also cleared whenever the gauge is off unless configured to save the readings.

Press and hold the button for about 1 second until MAX is displayed alternating with the units. The maximum reading will be continuously updated. The gauge may be left in this mode.

After MAX is displayed, press and hold the button for about 1 second until MIN is displayed alternating with the units. The minimum reading will be continuously updated. The gauge may be left in this mode. If excessive vacuum is applied to a pressure-only gauge while in this mode, the display will indicate -Err until the MAX/MIN readings are cleared.

After MIN is displayed, press and hold the button again for about 1 second until * * * * is displayed. The MAX and MIN memory is not erased and the gauge returns to normal operation with the display indicating the current reading.

fitting only

Operation—continued

Press and continue to hold the button until the display indicates clr MX/MN (about 3 seconds total) and then release the button. Both maximum and minimum values are cleared and the gauge returns to the normal mode and displays the current pressure.

Shut-Down

To shut off the gauge manually at any time, press and hold the button until the display indicates OFF (about 5 seconds) and then release.

When an auto shutoff timer is used, the display indicates OFF five seconds prior to auto shutoff. The button can be pressed to keep the gauge on. The auto shutoff and backlight (if equipped) timers are reset whenever the button is pressed and released.

If the gauge is set up without auto shutoff (on/off operation) it will stay on until manually shut off or until the batteries are depleted. Turn gauge off when not in use to conserve battery life.

Advanced ConfigurationBasic Configuration Battery Replacement

Accessing the Internal Buttons

1. Remove the 6 Phillips screws on the back of the unit.

2. Lift up the battery holder.

3. Move the battery holder to the side.

4. For gauges with the standad metal houseing, remove the battery cradle if necessary to gain access to the two internal buttons located near the lower right and left corners of the circuit board.

Auto Shutoff Time Selection

Auto shutoff time selection is done via the internal buttons to help prevent accidental or unauthorized changes. The selected shut off time is stored in non-volatile memory and will be retained even with the battery off or batteries removed.

Remove the rear cover to gain access to the two internal buttons located near the lower right and left corners of the circuit board.

With the gauge powered up, press and hold the DOWN button. Release the button when the auto shutoff time is displayed on the

upper display. The lower display will indicate AST M if the time displayed is in

minutes, and AST H if it in hours. An auto shutoff time of 0 signifies that the auto shutoff feature is

disabled and the front button turns the gauge on and off. Use the UP and DOWN buttons to select 0, 1, 2, 5, 10, 15, 20 or 30

minutes, or 1, 2, 4, or 8 hours. When the desired time is displayed, press and release the front but-

ton to save the selection and return to normal operation. Note: The gauge will automatically revert to normal operation if no

buttons are operated for approximately 15 seconds. Replace the battery holder assembly and rear cover taking care not

to pinch the power wires between the cover and the case.

Engineering Unit Selection

Engineering unit selection (except compound ranges) is done via internal buttons to help prevent accidental or unauthorized changes. The selected engineering unit is stored in non-volatile memory and will be retained even with the gauge off or batteries removed. The available engineering units depend on the sensor range and display resolution.

Compound (inHg/PSIG) gauges must be changed to display singleunit vacuum/pressure readings in the Advanced Configuration mode before different engineering units can be selected.

The default engineering units are mathematically converted to the newly selected engineering unit. When the gauge is powered up, the originally configured range is displayed and then the conversion with the selected engineering unit is displayed.

Powered the gauge up by holding the front button for 1 second. Press and hold the internal UP button. Release the button when the engineering units begin to flash. Use the UP and DOWN buttons to scroll through the list of engineer-

ing units available for the pressure range of the sensor. When the desired units are displayed, press and release the front

button to save the selection and return to normal operation. Note: The gauge will automatically revert to normal operation if no

buttons are operated for approximately 15 seconds. Replace the battery holder assembly and rear cover taking care not

to pinch the power wires between the cover and the case.

Advanced configuration requires a pass code for access and allows more features to be configured.

Remove the rear cover to gain access to the buttons located near the lower right and left corners of the circuit board.

With the gauge off, press and hold the UP button. Then press the front button. Release all buttons when the display indicates CFG and the program version then the full-scale range is indicated and the display is tested.

The display then indicates _ _ _ _ with the first underscore blinking, and with CFGPC (configuration pass code) on the character segments.

Note: The gauge will automatically revert to normal operation if no buttons are operated for approximately 15 seconds. To cancel and return to normal operation, press and release the front button without entering any pass code characters.

Pass Code Entry

The factory default is 3510, but this may be changed by the user under the Pass Code Configuration section.

1. Use the UP or DOWN buttons to set the left-most digit to 3.

2. Press and release the front button to move to the next position. The 3 will remain, and the second position will be blinking.

3. Use the UP or DOWN buttons to select 5.

4. Press and release the front button to index to the next position. 35 will remain, and the third position will be blinking.

5. Use the UP or DOWN buttons to select 1.

6. Press and release the front button to index to the next position. 351 will remain, and the fourth position will be blinking.

7. Use the UP or DOWN buttons to select 0.

8. Press and release the front button to proceed with configuration procedures.

If an incorrect pass code is entered, the gauge will return to the start of the pass code entry sequence.

Factory/User Configuration

The upper display section will be blank, and the lower section will display either USER_ or FCTRY.

If USER_ is selected, the user configuration can be modified as described in the following steps.

To select USER_, press and release the DOWN button. The lower display will indicate USER_. Press and release the front button to continue. If FCTRY is selected, the existing user configuration will be replaced

by the original factory configuration. To select FCTRY, press and release the UP button. The lower display will indicate FCTRY. Press and release the front button to restore the factory configura-

tion and restart the gauge.

Max/Min Configuration

Use the UP and DOWN buttons to select from the following: MX/MN Both highest and lowest values will be captured MX/--- Only highest value will be captured

--/MN Only lowest value will be captured

--/-- Capture feature is disabled

Press and release the front button to move to the next parameter.

Max/Min Memory

The upper display section will indicate clr. Use the UP and DOWN buttons to select from the following: AUTO Automatically clear max. and min. values when the

gauge is powered off MAN Manually clear max. and min. values Press and release the front button to move to the next parameter.

Gauge Type Configuration

This will only appear with 15, 100, or 200 psig ranges that were originally ordered as compound gauges.

Use the UP and DOWN buttons to select from the following:

-/+EU Vacuum is indicated as negative pressure in the

selected engineering units CMPND Vacuum is negative INHG, pressure is PSIG. This setting

will disable engineering unit selection. Press and release the front button to save the user configuration

and restart the gauge. Replace the rear cover taking care not to pinch the power wires

between the cover and the case.

Instructions F16B, F16BN

Gauges are calibrated at the factory using equipment traceable to NIST. There is no need to calibrate the gauge before putting it into service. Calibration intervals depend on your quality control program requirements, although many customers calibrate annually.

Calibration should only be performed by qualified individuals using appropriate calibration standards and procedures. The calibration equipment should be at least four times more accurate than the gauge being calibrated.

The calibration system must be able to generate and measure pressure/vacuum over the full range of the gauge.

A vacuum pump able to produce a vacuum of 100 microns (0.1 torr or 100 millitorr) or lower is required for vacuum and absolute gauges.

Warning: application of vacuum to non-vacuum models may result in irreparable damage to the sensor.

Allow the gauge to acclimate to ambient temperature for 20 minutes.

Remove the rear cover to gain access to the UP and DOWN buttons located near the lower right and left corners of the circuit board.

Install fresh batteries.

Calibration

Entering Calibration Mode

With the gauge off, press and hold the DOWN button. Then press the front button. Release all buttons when the display indicates CAL.

The display begins by indicating the full-scale positive pressure rating of the gauge in the engineering units as configured by the factory, and then shows all display.

Before the gauge enters the Calibration Mode, the display initially indicates _ _ _ _ with the first underscore blinking, and with CALPC (calibration pass code) on the lower display.

Enter the User-Modifiable Pass Code

The factory default is 3510, but this is user changeable.

1. Use the UP or DOWN buttons to set the left-most digit to 3.

2. Press and release the front button to move to the next position. The 3 will remain, and the second position will be blinking.

3. Use the UP or DOWN buttons to select 5.

4. Press and release the front button to index to the next position. 35 will remain, and the third position will be blinking.

5. Use the UP or DOWN buttons to select 1.

6. Press and release the front button to index to the next position. 351 will remain, and the fourth position will be blinking.

7. Use the UP or DOWN buttons to select 0.

8. Press and release the front button to proceed with configuration procedures.

If an incorrect pass code is entered, the gauge will return to the start of the pass code entry sequence.

Calibration Mode

The gauge enters and remains in the calibration mode until restarted manually or power is removed. Features not related to calibration are disabled and compound range models are set for the same engineering units for pressure and for vacuum.

The calibration may be performed in any of the available engineering units as well as percent (PCT). For greatest accuracy, use the UP and DOWN buttons to select engineering units for calibration with highest resolution (highest number of display counts). Press and

Calibration—continued

release the front button when the appropriate engineering units are displayed. Suggested units are listed below.

Sensor Suggested units for calibration 5 PSI 5.000 PSI 15 PSI 775.7 MMHG (TORR) 30 PSI 61.08 INHG 50 PSI 50.00 PSI 60 PSI 60.00 PSI 100 PSI 7.031 KG/CM2 200 PSI 407.2 INHG 300 PSI 610.8 INHG 500 PSI 500.0 PSI 1000 PSI 70.31 KG/CM2 2000 PSI 4072 INHG 3000 PSI 6108 INHG 5000 PSI 5000 PSI Any 100.00 PCT (percent)

The display will then indicate the currently applied pressure in the engineering units selected for calibration.

UP and DOWN Button Operation

Each time one of the calibration buttons is pressed and released quickly, a small change is made to the digitized pressure signal. It may take more than one of these small changes to result in a single digit change on the display.

To make larger changes, press and hold the appropriate calibration button. After about one second, the display will begin to change continuously. Release the button to stop. Then make fine adjustments by pressing and quickly releasing the calibration buttons as previously described.

Gauge Reference Pressure Gauges

Apply zero pressure by venting the gauge port to atmosphere. The character display will alternate between ZERO and CAL. Adjust for a display indication of zero using the UP and the DOWN buttons.

Apply full-scale pressure. The character display will alternate between +SPAN and CAL. Adjust for a display indication of fullscale pressure using the UP and the DOWN buttons.

Apply 50% full-scale pressure. The character display will alternate between +MID and CAL. Adjust for a display indication equal to 50% of full-scale pressure using the UP and the DOWN buttons.

Gauge Reference Vacuum Gauges

Apply zero pressure by venting the gauge port to atmosphere. The character display will alternate between ZERO and CAL. Adjust for a display indication of zero using the UP and the DOWN buttons.

Apply full-scale vacuum. The character display will alternate between +SPAN and CAL. Adjust for a display indication of fullscale vacuum using the UP and the DOWN buttons.

Apply 50% full-scale vacuum. The character display will alternate between +MID and CAL. Adjust for a display indication equal to 50% of full-scale vacuum using the UP and the DOWN buttons.

Absolute Reference Gauges

Apply full vacuum to the gauge. The character display will alternate between ZERO and CAL. Press the UP and DOWN buttons to obtain a display indication of zero.

Apply full-scale pressure. The character display will alternate between +SPAN and CAL. Press the UP and DOWN buttons to obtain a display indication equal to full-scale pressure.

Apply 50% of full-scale pressure. The lower display will alternate between +MID and CAL. Press the UP and DOWN buttons to obtain an indication equal to 50% of full-scale pressure.

Compound and Bipolar Gauges

In addition to the steps described above for pressure gauges, apply full-scale vacuum. The character display will alternate between –SPAN and CAL. Adjust for a display indication of actual applied vacuum using the UP and the DOWN buttons.

For bipolar and –30.00inHg/+15.00psig compound range models only, apply 50% full-scale vacuum. The character display will alternate between –MID and CAL. Adjust for a display indication equal to 50% of full-scale vacuum using the UP and the DOWN buttons.

Save Calibration

Once the adjustments are complete, press and hold the front button until the display indicates – – – – then release the button to store the calibration parameters in non-volatile memory and restart the gauge.

Verify the pressure indications at 0%, 25%, 50%, 75% and 100% of full scale.
