4. The alpha-numeric display reads SPAN 2 CAL TARGET=X (X represents the existing target value on
display). Change target value if required. Set the input pressure from the test standard to the target value
on the display. Wait for system to stabilize and press the
ENTER key on the display panel. See Table 5-7
as required.
5. The alpha-numeric display reads SPAN 3 CAL TARGET=X (X represents the existing target value on
display). Change target value if required. Set the input pressure from the test standard to the target value
on the alpha-numeric display. Wait for system to stabilize and press the
ENTER key on the display panel.
Repeat this step for SPAN target values 4 – 10.
6. The alpha-numeric display reads HYST.CAL TARGET=XXX (X represents the preset target value on
display. See Table 5-8.). Set the input pressure from the test standard to the target value on the
alpha-numeric display. Wait for system to stabilize and press the
ENTER key on the display panel.
NOTE: For absolute models, use a vacuum pump to reach the applicable hysteresis target value if below local
barometric pressure.
7. Save the calibration data by opening rocker switch S1 position 2 . The DLR3110 returns to normal mode
(see Section 5.3 on page 12).
8. Vent system and remove test standard and/or vacuum pump.
