Installation ST700 Dash Display System
24
You may set up the ST700 Dash Display System to display pressure
measurements using PSI or bar, and you may set the system to alert
the driver if the monitored value triggers a pre–set alarm—refer to
page 56 for relevant instructions.
1. Depending on the condition that you wish to monitor on your vehi-
cle, choose a suitable location for the sensor:
❑ Avoid mounting the sensor near sources of intense heat.
❑ Do not mount the sensor closer than 75 mm (3 inches) to ignition
leads, the distributor or the ignition coil.
❑ If possible, avoid mounting the sensor directly on the engine
block because excessive vibration will shorten its life expectancy.
2. Attach the sensor to its appropriate monitor point, if necessary
using suitable pressure hose and fittings.
