HARDWARE SET-UP
5.1
Power Requirements
The
TEMPEST 50
unit can be powered in three ways:
1.
Internal rechargeable battery
2.
Mains charger and connector
3.
12 V DC charger for use in a vehicle
5.1.1 Battery Operation - the
TEMPEST 50
is designed for
battery operation enabling 4-6 hrs continuous use. Fully recharging
the cell takes less than 2 hrs. The approximate percentage battery
charge remaining can be identified by pressing the STATUS key
(Refer to 0 in 6.1) when the unit is switched on. During operation a
low battery warning will indicate when recharging is necessary.
The internal battery will recharge automatically when the unit is
connected to either the mains (Section 5.1.2) or a 12 V DC power
source (Section 5.1.3) and the green power indicator next to the
battery symbol (9 in Fig 2) will illuminate to indicate that the unit is
charging whether the unit is operating or not.
5.1.2 Mains Adapter - the
TEMPEST 50
unit can be run
continuously from a mains socket using the standard mains charger
supplied. This adapter should be inserted into the charger socket (16
in Fig 3). To quick-charge (in 2 hours) the unit must be switched on,
otherwise the charging time will be greater than 5 hours.
5.1.3 12 V DC Adapter - the
TEMPEST 50
unit can also be run
continuously or charged from a normal car battery via the cigarette
lighter socket using an optional 12 V DC adapter. The power
connector leading from the adapter should be inserted into the
charger socket (16 in Fig 3).
5.2
Sample Probe Attachment
The sample tubing should be connected to the sample port (1 in Fig
1) or pressure port (3 in Fig 1) depending on which measurement is
being performed (emissions or draught measurement, respectively).
The yellow thermocouple plug should be correctly inserted (thinner
pin to the left) into the stack thermocouple socket (4 in
Figure 1) for stack temperature measurement.
