General information:
"A" means always channel A input;
"B" means always channel B input;
the signal on the channel A is managed
always according to this formula: (Fa/
Pu.1)*PS.1; the signal on the channel
B is managed always according to this
formula: (Fa/Pu.2)*PS.2. Where: Fa or
Fb is the frequency signal measured on
channel A or B; Pu.1 or Pu.2 is the
number of pulses per revolution gener-
ated by the sensor connected to channel
A or B; PS.1 or PS.2 is the prescaler
value of the sensor A or B.
F1 : frequency, tachometer, rate mode A or B channel
Input A

Input
Display
The instrument measures the frequency either on input A or on input B
and executes the following calculation: display=Fa/Pu.1*PS.1 (or Fb/
Pu.2*PS.2). It can be used, for example, to measure the rotation speed
of a motor, or to display frequency in Hz and kHz, as tachometer mode:
RPS, RPM, RPH, MPS, MPM, MPH and as rate meter: flow (m
