SILCA SIAMPU012ASY0100 the Truth Digital Pressure Gauges
SPECIFICATION INSTALLATION AND OPERATING INSTRUCTION
The TRUTH Digital Pressure Gauge has a precise ±1.0% full scale accuracy. The four digit digital display will reduce the potential for errors in readings by eliminating parallax errorr commonly produced with analog gauges. The TRUTH is packaged in an ABS plastic case. The unit is battery powered and has an auto- shut off to conserve battery life. A two-button key pad allows easy access to the features without the need to work through complex menus. These features include, auto zero, and conversion of the pressure units. Readings may be converted to various engineering units. See the chart for available units.
OPERATIONS INSTRUCTIONS
For the complete instructions for the functionality of the two buttons, see
the flow chart to the right. On/Off: To toggle between on and off. Press the
button. Device will automatically shut off after 20 minutes, if not used.
Zero: Zeros the display. Push and hold for 2 seconds to zero the display. If
after pressing the zero the display does not re-zero, the unit is no longer
meeting the specified accuracy and should be sent back to SILCA for
calibration. Do not use the Zero button when pressure is applied. Units: To
change units, press both On/Off and Zero buttons simultaneously. Overpressure
Indicator: The LCD will flash “OFL”, if the pressure applied is over 105% F.S.
“OFL” may also be displayed when the devise is subjected to electromagnetic
interference between 0.9 to 1 GHz.
MAINTENANCE
Battery Removal: Remove the outer rubber casing. Unthread the bolt on the
backplate. Lift backplate off by hand. Replace battery per polarity
indicators. Reverse steps to reassemble gauge. A “LOW BAT” descriptor
indication will appear on the display when batteries need to be replaced. This
symbol indicates waste electrical products should not be disposed of with
household waste. Please recycle where facilities exist. Check with your Local
Authority or retailer for reycling advice.
252 Gasket Replacement: When the rubber gasket has detiorated, you will need to replace the gasket. Order part: 252 Gasket. Unthread cap. Using a small screwdriver, you can remove the old gasket. Replace gasket and re-thread the cap back into place.
