• at the ‘ On ‘SQ’ ’ ( on.Sq ) parameter, configure the behavior of the
output signal when the operator is inside ‘ configuration menu ’ (see
section 10.3).
• select ‘ Output to high ’ ( to.hI ) to force the output signal to overrange
to maximum value
• select ‘
Output to low ’ ( to.Lo ) to force the output signal to
underrange to minimum value
• select ‘ Hold output ’ ( hoLd ) to hold the output signal while the
operator remains inside ‘ configuration menu ’.
• at the ‘ Power filter ’ ( P.FLt ) parameter, select a filter for specific power
frequency rejection. The filter selection has an effect on the response
times (see section 12).
• select ‘ No filter ’ ( nonE ) to disable frequency rejection filters. This
enables the fastest response time.
• select ‘
50 Hz filter ’ ( 50.hZ ) to enable rejection to 50 Hz frequency.
• select ‘ 60 Hz filter ’ ( 60.hZ ) to enable rejection to 60 Hz frequency.
• select ‘ 50 and 60 Hz filter ’ ( both ) to enable rejection to both 50 Hz
and 60 Hz frequencies. This is the slowest response time.
• at the ‘ Average filter ’ ( AVr ) parameter, configure the recursive filter
to be applied to measured input signal. The filter can be used to reduce
oscillations on noisy signals. Configure the filter strength between
‘0’ and ‘100’. The filter is stronger with higher values. Increasing the
strength of the filter slows the response speed of the instrument.
Value ‘0’ disables the filter.
• at the ‘ Dead band ’ ( d.bnd ) parameter set a value between ‘0.0’ %
and ‘100.0’ %. This is a percentage of the ‘ input signal high ’ parameter
configured at the ‘ Advanced scaling ’ section. Input signals below this
value, are treated as a ‘0’. This parameter applies to process, resistance
and potentiometer ranges, and it is disabled for temperature ranges
(thermocouples, Pt, Ntc).
example : instrument configured with code ‘011’ (0/10 Vdc = 4/20 mA)
and ‘input signal high’ parameter modified to 8 Vdc for an effective
input - output relation of ‘0/8 Vdc = 4/20 mA’. Configure the ‘Dead band’
parameter to ‘1.0’ to set a dead band value of 0.08 Vdc. All signals
below 0.08 Vdc will be treated as 0 Vdc, and the output will be 4 mA.
• the ‘ Version ’ ( VEr ) parameter informs about the firmware version
running in the instrument.
• at the ‘ Password ’ ( PASS ) parameter define a 4 digit code to
block access to the ‘ configuration menu ’. Activate the password to
prevent access to the instrument configuration by non authorized
personnel. To activate the ‘ Password ’ function select ‘ on ’, enter the
code and validate. The password will be requested when accessing
the ‘ configuration menu ’. The password does not block access to the
‘ force ’ menu. To deactivate the password, set the password value to
‘0000’.
• at the ‘ Factory reset ’ ( FAct ) parameter select ‘ yes ’ to activate the
default factory configuration (see section 15 for a list of factory
default parameters).
