GENERAL
The TTI 7
PLUS
comes ready for immediate use, with rechargeable batteries and built-in charger.
The instruments are switched on and off using the left hand buttons, marked appropriately. Connecting the mains
cord automatically enables the battery charging circuit and charges the batteries at the required rate. The LED
marked "LINE" will illuminate to show that mains power has been connected to the thermometer, and the LED
marked "FAST" will light when the batteries are low and the charger is charging at a high rate. The charger will
automatically reduce the charging current to a trickle charge as the batteries reach approximately 80% of full
capacity. Continuous trickle charging will not affect the batteries, and we recommend that the TTI 7
PLUS
is used with
the mains supply connected whenever possible.
To measure temperature, a suitable probe should be connected to input A or B. The measured temperature will be
displayed in large units and the actual resistance or voltage measured will be displayed in smaller units below,
together with the measuring current mode selected. In addition, the probe configuration and channel details will be
displayed along the top of the display.
