Operation 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 Use a pressure or vacuum range appropriate for the application.
4 Use clamp appropriate for the pressure range of the gauge.
4 Remove system pressures before removing or installing gauge.
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 damage! NEVER touch surface of diaphragm.
Gauges are not for oxygen service. Accidental rupture of sensor diaphragm may cause oil inside seal to react with oxygen.
Types of Gauges
Bipolar ranges read positive pressure and vacuum in the same units, and zero with the gauge port open.
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.
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. Remove the battery retainer. Remove batteries by lifting up the positive end of the battery (opposite the spring) taking care not to bend the battery holder spring.
3. Discard old batteries properly, do not discard into fire, sources of extreme heat, or in any hazardous manner.
4. Always replace both batteries at the same time with high quality alkaline batteries.
5. 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.
6. Replace battery retainer and back cover, including the rubber gasket and reinstall the six screws.

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

Instructions DSGB1
Operation—continued 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
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.
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 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.
Basic Configuration
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. Locate 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.

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.

Instructions DSGB1
Calibration Preparation
Gauges are calibrated at the factory using equipment traceable to
NIST. Gauges are calibrated in an upright position at normal ambient temperatures (approx. 20°C). There is no need to calibrate the gauge before putting it into service unless the process temperature and gauge position deviate from normal.
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. Warning: application of vacuum to non-vacuum models will result in damage to the sensor.
Allow the gauge to acclimate to the calibration temperature for at least 60 minutes. Calibrate the gauge at the same temperature as the process with the gauge oriented in the same position.
Install fresh batteries before calibration.
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.
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.
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 release the front button when the appropriate engineering units are
