Press ‘SQ’ (
<
) for 1 second to access the ‘configuration menu’.
For a description on how to operate inside the menus see section
1.17
. For a full vision of the ‘configuration menu’ structure see
section
1.20
.
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.
• ‘ C inhibition ’ (‘ cnI.3 ’) - counter mode with inhibition con-
trol. Impulses input at channel A. Inhibition control on channel B.
• ‘ C 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.

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 9999.
• assign the value for parameter ‘ Divider ’ (‘ dIV ’) from 1 to 9999.
• assign the value for ‘ Preset ’ (‘ PrSt ’) from -1999 to 9999. Reset acti-
vation loads on display the preset value.
• 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.
1.19.2 Configuration for ‘cn.1’
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 ’.
