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, except

batteries. 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 lead, 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

Power-Up and Normal Operation

Your gauge is ready to use. It was factory calibrated just prior to shipment with batteries installed.

Press and hold the center power button for approximately 1 second. The display is tested.

The full-scale range in the factory default units is indicated. If the units were changed by the user, then the full scale range in the selected engineering units is displayed.

The display test is briefly shown again.

The actual pressure and units are displayed. The gauge is ready for use and readings are updated approximately 3 times per second

For gauge reference models occasional flashing of the minus sign is normal and indicates the gauge is at zero pressure. Absolute gauges only display zero at full vacuum.

Display Backlighting (BL Models Only)

Display backlighting can be turned on by momentarily pressing the power button whenever the gauge is on. This also restarts the auto shutoff timer.

F20B: The backlighting will turn on for 1 minute and then automatically shut off.

F22B: The factory default on-time is 1 minute, but the setup procedure allows setting it to 1 to 255 minutes, or to 0 to disable display backlighting.

The red LED display backlighting will not be apparent under bright lighting conditions.

Error or Out-of-Range Indications

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

If excessive vacuum is applied to a pressure-only gauge, the display will indicate

-Err until the vacuum is released. Applying vacuum to a pressure-only gauge can damage the pressure sensor.

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

- or -

Zero the Display

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 is in the normal operating mode. The gauge port must be exposed to normal atmospheric pressure with no pressure or vacuum applied.

Press and hold the Zero/Clear button.

Continue to press the Zero/Clear button until oooo is displayed then release the button.

The gauge in now zeroed.

Occasional flashing of the minus sign with zero pressure/vacuum is normal.

The stored zero correction is erased when the gauge is shut off.

Shutoff

The auto shutoff timer starts at power up and resets whenever any button is pressed. The default time is 5 minutes, but can be set for a variety of times. If on/off operation is selected, the gauge will stay on until manually shut off or the batteries are depleted. Turn gauge off when not in use to conserve battery life.

When an auto shutoff time is used, the display indicates OFF five seconds prior to shutoff. Press the power button to keep the gauge on.

To shut the gauge off manually, press and hold (about 5 seconds) the center power button until OFF is displayed.

Instructions F20B, F22B

F20B Memory

With the gauge powered up and in the normal operating mode, press and release the Memory button to sequence through the memory locations.

When the Memory button is pressed the gauge is in the peak hold mode. A new higher reading will replace an existing reading, but a pressure reading lower then the one displayed will not be saved.

When desired memory location is displayed, take the pressure reading. The peak reading will be captured.

Remove the gauge from the pressure source and press the memory button for the next location.

Repeat until all readings are taken. The readings will be saved even if the

gauge is shut off.

Press and release the Power button to exit the memory mode and return to live pressure readings.

F22B Min/Max Memory

The Min/Max setup procedure in the Gauge Configuration > F22B Min/Max Setup section may be used to configure the gauge to

capture both maximum and minimum values, the maximum value only, or the minimum value only. Only the configured values will be displayed when the memory button is pressed. The gauge also may be configured to erase or save the readings when the gauge powers down.

The Min/Max readings are captured at the rate of 3 times per second. Note that if a brief pressure deviation occurs, it may not be captured. The readings are captured any time the gauge is on and not in the configuration or calibration mode.

Press and release the Memory button to view the maximum stored value.

The center power button may be pressed at any time to return to the normal display mode.

The gauge may be left in the maximum display mode if desired. The maximum reading will be continuously displayed, stored and updated.

Press and release the Memory button to view the minimum stored value.

Calibration

Setup and Preparation

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 should only be performed by qualified individuals using appropriate calibration standards and procedures. Calibration intervals depend on your quality control program requirements, although many customers calibrate annually.

The calibration system must be able to generate and measure pressure/vacuum over the full range of the gauge and should be at least four times more accurate than the gauge being calibrated.

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

Allow the gauge to acclimate to ambient temperature for 20 minutes. Install fresh batteries.

Entering Calibration Mode

With the gauge off, press and hold the t button. Then press the Power 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 3510 pass code as described in the Configuration Pass Code section.

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 s and t buttons to select engineering units for calibration with highest resolution (highest number of display counts).

Press and release the Power 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 or 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 3447 KPA 1000 PSI 6895 KPA 2000 PSI 4613 FTH2O 3000 PSI 6920 FTH2O 5000 PSI 5000 PSI

The display will then indicate the currently applied pressure in the

engineering units selected for calibration.

s and t Button Operation Each time one of the s or t 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 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 buttons as previously described.
