The next menu accesses the configuration parameters for the 'function mode' ('Func')
selected. Configuration parameters are slightly different for each 'function mode'. In
the next entries, all 7 possible configuration menus are explained, 'cnF.1' to 'cnF.7', one
for each 'function mode'.

1.19.1 Initial set-up

To configure the initial set up of the instrument, select the function
mode, the decimal point position, scale the reading and configure
the mode selected and the sensor.
Enter the 'Function mode' ('Func') menu and select the desired func-
tion, from the 5 counting modes, 2 ratemeter modes and the period-
meter mode available.
• 'Counter' ('cn. 1') - normal counter mode. Impulses input at chan-
nel A. Channel B disabled.
• 'Counter quadrature' ('cnq.2') - counter mode for quadrature sig-
nals. Impulses input at channel A and B, in quadrature.
• 'Counter + inhibition' ('cnI.3') - counter mode with inhibition con-
trol. Impulses input at channel A. Inhibition control on channel B.
• 'Counter + control add / substract' ('cnc.4') - counter mode with
control for add / substract. Impulses input at channel A. Control for
the add or substract function on channel B.
• 'Counter differential' ('cnd.5') - counter mode with differential
function. Impulses received at channel A add. Impulses received at
channel B substract.
• 'Ratemeter' ('rt.6') - ratemeter mode. Impulses input at channel
A. Channel B disabled.
• 'Ratemeter quadrature' ('rtq.7') - ratemeter mode for quadrature
signals. Impulses input at channel A and B, in quadrature.
• 'Periodmeter' ('Prd.8') - periodmeter mode. Impulses input at
channel A. Channel B disabled.
Access the 'Decimal point' ('dP') menu to select the decimal point
position. Move the decimal point by pressing the 'LE' (3) key.
Configure the function mode selected ('cnF.2' to 'cnF.8'). See sec-
tions 1.19.2 to 1.19.9.
Configure the sensor at the 'SnSr' menu. See section 1.19.10.

1.19.2 Configuration for 'cn.1'

Multiplier
1 to 999999
Configuration menu for mode 'counter' ('cn.1'). Total impulses re-
ceived are multiplied by the value of the 'multiplier' ('MuLt') register
and divided by the 'divider' ('dIV') register. Result is refreshed on the

display.
• assign the value for parameter 'Multiplier' ('MuLt') from 1 to
Preset value
999999.
-199999 to 999999
• assign the value for parameter 'Divider' ('dIV') from 1 to 999999.
Up
• assign the value for 'Preset' ('PrSt') from -199999 to 999999. Reset
activation loads on display the preset value.
Down
• select the counting mode ('ModE') to 'uP' for upwards counting
(impulses received add) or 'doWn' for downwards counting (impuls-
es received substract).
• to activate the 'FAST' mode ('FASt') select 'on'. See section 1.16 for
more information on the 'FAST' mode.
