DPF20 Frequency, rate, total or period counter Instruction Manual
Conguraon menu for mode ‘counter dierenal’ (‘cnd.5’). To-
tal impulses received are mulplied by the value of the ‘mulplier’
(‘MuLt’) register and divided by the ‘divider’ (‘dIV’) register. Result is
refreshed on the display.
• assign the value for parameter ‘Mulplier’ (‘MuLt’) from 1 to
999999.
• assign the value for parameter ‘Divider’ (‘dIV’) from 1 to 999999.
• assign the value for ‘Preset’ (‘PrSt’) from -199999 to 999999. Reset
acvaon loads on display the preset value.
Impulses received on channel A add. Impulses received on channel
B substract.
1.19.6 Conguraon for ‘cnd.5’
Conguraon menu for mode ‘ratemeter’ (‘rt.6’). Frequency mea-
sured is mulplied by the value of the ‘mulplier’ (‘MuLt’) register
and divided by the ‘divider’ (‘dIV’) register. Result is refreshed on the
display. Measure is updated at the rate dened on the ‘GATE’ regis-
t e r.
• assign the value for parameter ‘Mulplier’ (‘MuLt’) from 1 to
999999.
• assign the value for parameter ‘Divider’ (‘dIV’) from 1 to 999999.
• select the value for the ‘Time window’ (‘GAtE’). Available values
are : 0.5, 1.0, 2.0, 4.0, 8.0 or 16.0 seconds. The me window denes
the display refresh me. This parameter has no eect if the ‘SLOW’
mode is acve.
• for slow frequencies acvate the ‘SLoW’ parameter conguring the
‘tIME’ parameter between 1 and 1000 seconds. Congure the ‘nuMb’
parameter between 1 and 32 impulses. See secon 1.15 for more in-
formaon on the ‘SLoW’ mode.
• in case of unstable signals, acvate the ‘average lter’ (‘AVr’) func-
on. It acvates a recursive lter on the reading. the lter is stronger
for higher values, from 0.0 to 99.9.
1.19.7 Conguraon for ‘rt.6’
1.19 Conguraon menu (cont.)
Conguraon menu for mode ‘ratemeter quadrature’ (‘rtq.7’).
Frequency measured is mulplied by the value of the ‘mulplier’
(‘MuLt’) register and divided by the ‘divider’ (‘dIV’) register. Result is
refreshed on the display. Measure is updated at the rate dened on
the ‘GATE’ register.
• assign the value for parameter ‘Mulplier’ (‘MuLt’) from 1 to
999999.
• assign the value for parameter ‘Divider’ (‘dIV’) from 1 to 999999.
• select the value for the ‘Time window’ (‘GAtE’). Available values
are : 0.5, 1.0, 2.0, 4.0, 8.0 or 16.0 seconds. The me window denes
the display refresh me. This parameter has no eect if the ‘SLOW’
mode is acve.
• select the ‘edges’ to count for each quadrature cycle (‘q.124’). Se-
lect ‘1--1’ for 1 impulse per quadrature cycle. Select ‘1--2’ for 2 im-
pulses per quadrature cycle. Select ‘1--4’ for 4 impulses per quadra-
ture cycle.
