setting is 0.5 %cap/°C which is typical for most batteries. The
setting OFF disables temperature compensation.
Default : 0.5 %cap/°C
Range
Stepsize : 0.05 %cap/°C
F13 : Time-to-go averaging period. Specifies the time window in
minutes the moving averaging filter works with. Selecting the
right time depends on your installation. A value of 0 disables
the filter and gives you instantaneous (real-time) readout,
however the displayed values may fluctuate heavily. Selecting
the highest time (12 minutes) ensures that long term load
fluctuations are included in the time-to-go calculations.
Default : 3 minutes
Range
F14 : Current threshold. When the measured current falls below this
value it will be considered as zero Amps. With this function it
is possible to cancel out very small currents which can
negatively affect long term state-of-charge readout in noisy
environments. For example if an actual long term current is
+0.05A and due to injected noise or small offsets the battery
monitor measures –0.05A, on the long term the SBM-01 can
wrongly indicate that the battery needs recharging. When in
this case Function 14 is set to 0.1, the SBM-01 calculates with
0.0A so that no wrong assumptions can be made. A setting of
0.0 disables this Function.
Default : 0.0A
Range
Stepsize : 0.1A
F15 : Temperature unit selection. This Function enables selection
between degrees Celsius (°C) and degrees Fahrenheit (°F)
temperature readout.
Default : °C
Range
F16 : Voltage prescaler. This Function is only important when an
optional prescaler is installed on the battery voltage sense
input of the SBM-01. The voltage-charged-parameter,
undervoltage- and overvoltage alarm settings are linked with
