1.2 Impulse counter modes
The instrument allows for 5 selectable impulse counter modes :
• Counter (‘ cn.1 ’) (see section 1.19.2)
• Counter quadrature (‘ cnq.2 ’) (see section 1.19.3)
• Counter with inhibition (‘ cnI.3 ’) (see section 1.19.4)
• Counter with control add / substract (‘ cnc.4 ’) (see section 1.19.2)
• Counter differential (‘ cnd.5 ’) (see section 1.19.6)
Configurable up or down counting, ‘reset’ at rear terminals, front key
and/or at alarm activation. Configurable ‘Preset’ value. Relay activa-
tion and deactivation delays.
Alarm functions with ‘return to preset’ or ‘reset to 0’ generate cycles
of counting (instrument counts from ‘preset’ value to alarm value
in never ending cycle). The instrument provides memory of cycles
counter.
Scalable reading with configurable multiplier factor (1 to 9999) and
configurable divider factor (1 to 9999). Memory retention in case or
power loss. Retains configuration and last reading.
Counting frequency up to 250 KHz, in ‘
FAST ’ mode (see section 1.16).
1.3 Ratemeter modes
In ratemeter mode the reading is proportional to the measured fre-
quency. The instrument allows for 2 selectable ratemeter modes :
• Ratemeter (‘ rt.6 ’) (see section 1.19.7)
• Ratemeter quadrature (‘ rtq.7 ’) (see section 1.19.8)
The ratemeter mode has a single input channel, with scalable read-
ing. The quadrature ratemeter mode has 2 inpur channels available
for detection of sense of turn when working with quadrature signals.
Scalable reading with configurable multiplier factor (1 to 9999) and
configurable divider factor (1 to 9999).
For low frequency applications, the ‘
SLOW ’ mode provides the best
response time for each application (see section 1.15).
Maximum frequency up to 900 KHz and minimum frequency down to
de 0.001 Hz (1 mHz) with ‘
SLOW ’ mode active.
Reading is proportional to the signal period. Scalable reading with
configurable multiplier factor (1 to 9999) and configurable divider
factor (1 to 9999).
For applications with long periods (slow frequencies), the ‘
SLOW ’
mode provides the best response time for each application (see sec -
tion 1.15).
