Upon proper adjustment of the Temperature Zero, change the temperature simulator
value to -60 °C. Adjust the Temperature Span value so that the temperature displayed
equals the calibrator set value. Recheck the value at 25 °C and repeat adjustment if
necessary. Check calibration at desired temperature intervals for verification.

Vacuum Value

To adjust the Vacuum value, open the condenser door and adjust the trim pot located
on the main Sentry 2.0 module within the electrical box. Set the value to 760 Torr, or
current atmospheric pressure. Turn the vacuum trim pot clockwise to increase the
pressure or counter-clockwise to decrease the pressure.

Once the rough vacuum has been set, connect a reference tube. Adjust the Vacuum
value located on the LCD screen up to increase the Vacuum reading. Adjust the
Vacuum value down to decrease the Vacuum reading.

Note: SP Scientific recommends the use of a Varian Vacuum Reference Tube for vacuum
calibration.

PRACTICAL OPERATING TIP. ENSURE THAT THE GROUND WIRE IS FIRMLY
CONNECTED BEFORE CALIBRATING ANY VALUES. A LOOSE GROUND WIRE CAN
PRODUCE INCONSISTENT AND UNPREDICTABLE RESULTS.
