System Setup

provided display ribbon cable to the main board before applying power if the instrument
will be conﬁgured using the user interface via the display.

Warning: Be sure the black colored side at the end of the ribbon is against
the darker brown connector clamping piece on the mating connector.
Do NOT connect or disconnect the ribbon cable while power is applied.

Connect the AC-DC power supply to the power input connector on two-pin connector
item 5 in Fig. 5. Connect item 5 to main board to apply power. To facilitate the use of a
battery to power the STAP, DC voltages between 10 and 15 Volts may be used and should
be connected to the Molex power in connector provided with the unit. Any AC adapter
with an output of 10-15 Volts DC at 1 AMP can be used to power the STAP. The instrument
ﬁrmware automatically runs when power is connected. Ensure the power plug is fully
seated in the connector before connecting the instrument to a computer.

Connect the sample thermistor attached to the sample LFE to the connector item 1 in Fig.
5 on the main circuit board.

If the vacuum pump 2-pin connector is not connected to the main board, then connect
it to the receptacle on the main board near the pump head.

6.5 Communication Connections

Connect the various cables provided with the STAP as described in the table below.
