The high/low data values are cleared. Zeroing the Display Hold the [Zero] button until the On/Off Zero Clear the display shows "-0-" (about 5 seconds). The instrument will retain this zero value even after the instrument has been turned off. DPG 100 Rev Feb 2001... -
Page 11: Restoring The Calibrated Zero
In order to obtain optimum performance from the instrument when testing or re-calibrating, obey the following recommendations: • Allow a 5-minute warm-up period before testing or calibration. • The pressure standard you use should be at least 4 times more accurate than the specification of the instrument. DPG 100 Rev Feb 2001... -
Page 12: Required Pressures
Apply the indicated pressure to the instrument. Press [Clear] until "-P-"is displayed, indicating that the reading is being stored. Next, the display will begin to alternately flash between the pressure required for calibration point #1 (for example, "050.0”') and ” - ---". DPG 100 Rev Feb 2001... -

Otherwise... Once the setting you want is displayed, press the [Zero] button to store this setting into memory. After the instrument stores the setting into memory, the next menu item will be displayed. DPG 100 Rev Feb 2001...

Page 20: Low Limit Setpoint ("L-Lo") Menu Item
This feature disables the ability to read the stored high and low values on the display. The display will always read the "live" tracking value of the process pressure. When the [Hi/Lo] button is pressed, the display will momentarily read "-EO-" which indicates that the button has been disabled via the Enable Options menu item. DPG 100 Rev Feb 2001... -
