Types of Gauges

Gauge reference sensors always read zero with an open gauge port.

Ranges 1000 psi and higher use a 14.7 psi sealed reference sensor.

They are functionally similar to gauge reference sensors.

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

Compound ranges read inHg for vacuum and psig for pressure.

Absolute reference gauges read zero at full vacuum. With an open gauge port, their readings will vary due to continuously changing barometric pressure.

Error or Out-of-Range Indications

Attempting to zero the gauge with reading greater than approximately 3% of fullscale pressure or vacuum will result in an error condition. The display will alternately indicate Err 0 and the reading. Press the power button 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.

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 Permanent installations must be indoors only. Outdoor or wash down applications require 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 nonvacuum 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.

Power-Up and Normal Operation

Your gauge is ready for use. It was 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, the full scale range in the selected engineering units is then displayed.

The display test is briefly shown again.

Display Backlighting

The factory default on-time for display backlighting is 1 minute. It turns on for one minute when the gauge is first turned on or whenever any button is pressed. This also restarts the auto shutoff timer.

In user configuration, the backlight time can be set from 1 to 255 minutes, disabled to save battery life, or set to be on whenever the gauge is on.

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

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.

Battery Replacement

A low battery indication will be shown in the upper lefthand corner of the display when the battery voltage falls sufficiently. The batteries should be replaced soon after the indicator comes on or unreliable readings may result.

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

2. Lift up the battery holder if necessary.

3. Remove batteries by lifting up the positive end of the battery

(opposite the spring) taking care not to bend the battery holder spring.

4. Discard old batteries properly, do not discard into fire, sources of extreme heat, or in any hazardous manner.

5. Always replace both batteries at the same time with high quality alkaline batteries.

6. Install batteries with correct orientation. Incorrect polarity will damage the gauge. The negative (flat) end of each battery should be inserted first facing the battery holder spring.

7. Replace battery holder and back cover, including the rubber gasket and reinstall the six screws.

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 and absolute 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 passcode) on the lower display.

Enter the 3510 passcode as described in the Configuration

Passcode section.

Calibration Mode

The gauge 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 number of display counts.

Press and release the Power button when the appropriate engineering units are displayed. Suggested units are above right.

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 button press to make a 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.

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 s and t buttons.

Note: At this point you may re-zero the gauge without doing any other calibration. Press and hold the Power button until the display indicates - - - - then release the button to store the new zero in non-volatile memory and restart the gauge.

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

Press and hold the Power button until the display indicates - - - - then release the button to store the calibration parameters in nonvolatile memory and restart the gauge.

Verify readings at 0%, 25%, 50%, 75% and 100% of full scale.
