Restarting The Baseline Measurement; Clearing And Exiting From The Baseline Pressure Procedure; Auto-Off Feature - TEC DG-700 Operating Instructions Manual

Once you are satisfied with the baseline pressure
reading, press the ENTER key to accept and enter
the baseline pressure reading into the gauge. After
pressing ENTER, Channel A will now display the baseline
adjusted pressure reading (i.e. the measured baseline pressure
reading will be subtracted from the current Channel A pressure
measurement). The icon "ADJ" appears in the Channel A display to indicate that the baseline adjusted pressure
reading is displayed. The time averaging period for the gauge reverts back to whatever period was selected prior to
pressing the BASELINE button. In addition, Channel B also reverts back to displaying an unadjusted pressure
reading.
Now create a change in the operating condition of the building
(e.g. turn on and exhaust fan). Channel A will display the
change in building pressure caused by the change in operating
condition.

1.6.b Restarting the Baseline Measurement:
During a baseline measurement procedure (i.e. while the gauge is recording the long term average
baseline pressure), the baseline measurement procedure can be restarted by pressing the START button.
When START is pressed, the measurement buffer and time counter for the baseline reading is cleared
and a new baseline reading is immediately started.
Once a baseline measurement has been taken and entered into the gauge (i.e. ADJ appears below the
Channel A reading), a new baseline measurement procedure can be initiated by pressing the
BASELINE button.

1.6.c Clearing and Exiting from the Baseline Pressure Procedure:
Pressing the CLEAR button clears the baseline measurement buffer and turns the baseline feature off.
The gauge will remain in the operating mode selected prior to the BASELINE button being pressed.
Note: If the gauge Mode is changed while the baseline measurement feature is active, the baseline measurement
buffer is cleared and the baseline feature is turned off.

1.7 Auto-Off Feature

In order to preserve battery life, the DG-700 gauge will automatically shut off if no keys are pressed for 2 hours. The
auto-off feature can be disabled by simultaneously pressing the CLEAR and ENTER buttons. The auto-off feature
is automatically re-enabled whenever the gauge is turned off and then back on.
