1.19 Configuration menu (cont.)
Configuration menu for mode ‘ periodmeter ’ (‘P rd.8 ’). Period mea -
sured is multiplied by the value of the ‘multiplier’ (‘ MuLt ’) register
and divided by the ‘divider’ (‘ dIV ’) register. Result is refreshed on the
display. Measure is updated at the rate defined on the ‘ GATE ’ regis -
ter.
• assign the value for parameter ‘ Multiplier ’ (‘ MuLt ’) from 1 to 9999.
• assign the value for parameter ‘ Divider ’ (‘ dIV ’) from 1 to 9999.
• 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 time window defines
the display refresh time. This parameter has no effect if the ‘ SLOW ’
mode is active.
• for long periods activate the ‘
SLoW ’ parameter configuring the
‘ tIME ’ parameter between 1 and 1000 seconds. Configure the ‘ nuMb ’
parameter between 1 and 32 impulses. See section 1.15 for more in -
formation on the ‘ SLoW’ mode.
• in case of unstable signals, activate the ‘ average filter ’ (‘ AVr ’) func -
tion. It activates a recursive filter on the reading. the filter is stronger
for higher values, from 0.0 to 99.9.
1.19.9 Configuration for ‘Prd.8’
• for slow frequencies activate the ‘ SLoW ’ parameter configuring the
‘ tIME ’ parameter between 1 and 1000 seconds. Configure the ‘ nuMb ’
parameter between 1 and 32 impulses. See section
1.15
for more in -
formation on the ‘ SLoW’ mode.
• in case of unstable signals, activate the ‘
average filter
’ (‘
AVr
’) func -
tion. It activates a recursive filter on the reading. the filter is stronger
for higher values, from 0.0 to 99.9.
1.19.10 Sensor configuration
The sensor configuration menu (‘ SnSr ’) provides configuration for
the input section of the instrument, the excitation voltage and the
trigger level, for accurate detection of the impulses.
• ‘ Automatic configuration’ (‘Auto’) - if a standard sensor is used,
select one of the sensors provided at the ‘ Auto ’ menu list. The instru -
ment will automatically configure the parameters according to Table
2 (see section 1.8) . If this configuration does not detect impulses,
manually modify the values for the parameters indicated below.
