3.1.3.3.1. Alternator frequency factor
IMPORTANT: When setting the alternator frequency factor (
aff
), enter also the first decimal place for greater
accuracy. In other words, if the
aff
= 36, the value you enter is 360 (
aff
x 10).
Number of revolutions per minute (rpm) is measured as the number of pulses per minute on the alternator
/ generator. Depending of the alternator it could output 4
– 8 pulses per revolution. If you don’t know the
alternator frequency factor (from alternator model) you could calculate it. To calculate alternator frequency
factor, you need to know the diameter of the crankshaft V-belt pulley and the alternator V-belt pulley, and
then calculate it using the following formula:

aff
= alternator frequency factor
𝑑
1
– diameter of the crankshaft V-belt pulley
𝑑
2
- diameter of the alternator V-belt pulley
p
– alternator number of pulses per revolution
3.1.3.3.2. Data saving period
This number represents the interval time (in seconds) for saving data in the logger memory. For the default
value of
M
= 10sec
, the logger will save its measured data every 10 sec. The value of
M
can be set from 1
to 250 sec.
