Instructions for the use of the 30.2011
This digital thermometer is an eIectronic precision instrument for the measurement of internal and external
temperatures specially adapted for installation in motor vehicles. The instrument also warns of ground frost,
has an illuminated display if connected to a 12V system and shows the time.
Measurement range Internal: 0°C I + 499°C External: -40°C I + 80°C
(32°F1+122°F) (-40°F1+178°F)
Scalale: 0.5°C (0.5°F) Battery: 1.5 V button cell
Max. Error: 1°C (18°F) Cable length: approx 3 m
Caution: used batteries should be disposed of separately
Installation
1. Find a suitable space visible from the driving seat where the thermometer can be installed either with it's
adjustable holder or using the enclosed Velcro fastening. Ideally, this should be close to a cable bushing
and it you want to connect the thermometer to the vehicle electric system there must be a connection
availabe (see 4.2)
2. Lead the external sensor through a cable bushing (e.g. the radio antenna bushing) and through the
engine space to the front bumpar. Attach the self-adhesive sensor to the rear of the front bumper in a
protected position that you have first cleaned thoroughly of all dirt, rust and grease. Secure the wire in
the engine space to the wall or another cable with clamps or insulating tape to prevent it dangling free.
3. Before using the thermometer check proper, secure and safe siting of the external sensor wire in the
battery/cable plug receptacle of the thermometer
4. Connect to currents as following:
4.1 Operation with enclosed round cell
Insert battery in battery/cable plug receptacle and close cover. Make sure the cable to the external
sensor is properly sited and connected.
4.2 Operation on 12V circuit (vehicle battery)
a. Remove the round celI from the battery receptacle
b. Attach the enclosed wiring connector to the 3-pole 12V connection in the battery plug
receptacle
c. Crimp the enclosed cable lugs on the uninsulated cable ends
d. Connect red cable to vehicIe bettery (KL 30)
e. Connect grey cable to 12V light connection (KL58)
