Program Mode. Once a programmable register is selected the key can be used to edit that register. PRGM & ENTER Puts the manometer into the Program Mode from the Measure Mode. When in the Program Mode, pressing this key selects the programmable register to be edited (with prompt for password if Lockout is set). -
Page 7: Zeroing The Manometer
Zeroing the Manometer To zero the manometer, first turn off pressure sources and vent pressure ports to atmosphere. The display should read close to zero. Press the MIN/MAX and HOLD keys at the same time and then release. This begins the zeroing process. The top line of the display reads “ZERO IN PROGRESS”... -

Page 12: User Info Select
User Info Select The User Info Select registers are designed to provide the user with information on the hardware and software in the manometer. This register provides read only information on the sensor’s serial number, software version and date of manufacture. It also allows the user to edit the Auto Shut-Off, Lockout and Start-Up Header Name features. -
Page 13: Auto Shut-Off
Auto Shut-Off Enabling the Auto Shut-Off feature allows the manometer to turn itself off after a user selected period of keypad inactivity. Selectable options include DISABLED, 10 Minutes (which is the factory shipped default), 20 Minutes, 30 Minutes, 45 Minutes and 60 Minutes. -
Page 14: Lockout Select
Lockout Select Enabling the Lockout feature prevents unauthorized users from making changes to the configuration of the manometer. To enter the Program Mode, the user must first enter the “password” (two- digit Lockout Code) within approximately 40 seconds when prompted. Failure to enter the correct two digit code within approximately 40 seconds will return the unit to Measure Mode. -
Page 15: Header Name
Header Name Follow the steps below to edit the Header Name. Keystroke Display 1. From the Measure Mode Top line reads “PROGRAM press the PRGM key. MODE” and bottom line reads “UNITS SELECT”. 2. Press the arrow key Bottom line changes to “USER twice. -
Page 16: Contrast Select
Contrast Select The Contrast Select register allows the user to adjust the character contrast of the LCD display to provide the best visibility for the ambient light conditions. To adjust the contrast, follow these steps: Keystroke Display 1. From the Measure Mode Top line reads “PROGRAM press the PRGM key. -
Page 17: Data Logging
Data Logging Data Logging can be used to record pressure measurements. Two record modes are supported: automatic and manual. In automatic mode, a pressure value is captured every 5 seconds for 20 minutes, resulting in 240 stored values. In manual mode, a pressure value is captured each time the PRGM key is pressed up to 240 values. -
Page 18: Leak Test
Leak Test The Leak Test feature allows the user to determine the leak rate in the pneumatic system being monitored. Once configured, Leak Test monitors the measured pressure over time and displays the leak rate in the pressure units per minute at the conclusion of the test. -
Page 19: Re-Calibration
Re-Calibration The manometer can be re-calibrated in the field for zero, span, and linearity. The proper primary standards must be available prior to calibrating the manometer. These standards should meet the accuracy requirements for your company or industry. The factory follows the guidelines established by ANSI / NCSL Z540-1-1994 which requires that the primary standard be 4 times more accurate than the unit under test. -
