It is also possible to use the vehicle's 12 V power system as the primary supply
for a CR5000 with a battery base (Figure 1.6-2). When a vehicle’s starting
motor is engaged, the system voltage drops considerably below the 11 volts
needed for uninterrupted datalogger function. Diodes in the CR5000 in series
with the 12 V Power In connector allow the battery base to supply the needed
voltage during motor start. The diodes also prevent the separate power
systems of the CR5000 and vehicle from attempting to charge each other.
Because this configuration does not charge the CR5000 batteries, it is not
recommended.
