10 Installation
10.1 Connection Diagram
The use of an external 1A fuse is recommended. Connect the supply terminals to your vehicles power supply. The EMS-3
can be used on both 12V and 24V without the use of any pre-regulators. Ensure that the supply voltage will not drop
below 8V during operation as this may result in incorrect readings.
Please note
: It is essential that a single wire be connected from the minus terminal of the
instrument to the engine block. This wire must not be used to share currents with other electrical
users as this can affect accuracy of readings.
