13. Configuration menu (cont.)
At the ‘ Display information ’ ( dISP ) menu select one parameter to read
on display when the instrument is in ‘ normal mode ’ of operation. If you
need access to more than one information, see the ‘ messages ’ function
(see section 13.8) associated to front key ‘ LE ’ (
3
).
• select ‘ Measure ’ ( MEAS ) to read the value of the actual millivolts at
signal terminals (for example: ‘ MEAS mV 7.82 ’). Value is expressed in
millivolts (see section 10.1).
• select ‘ Tare ’ ( tArE ) to read the actual value of the ‘ tare ’ parameter.
(for example : ‘ tArE mV 1.27 ’) This value is expressed in corrected
millivolts (mV’) (see section 10.1).
• select ‘ Input signal value ’ ( InP.S ) to read the input signal value and
the measurement units (for example: ‘ Inp mV 8.52 ’). This value is
expressed in millivolts (mV’) (see section 10.1).
• select ‘ Output signal value ’ ( out.S ) to read the output signal value
and the measurement units (for example : ‘ Out mA 12.40 ’).
• select ‘ Label ’ ( LAbL ) to read the value configured at the ‘ label ’ and
‘ label2 ’ parameters (see section 13.9).
• select ‘ Process value ’ ( Proc ) to read the process value as scaled at
the process parameters (see section 13.4) (for example: ‘ Proc 150.0 ’).
• select ‘ Percentage ’ ( Prct ) to read the percentage of input signal,
where ‘0’ is the value assigned to the ‘ input signal low ’ parameter, and
‘100’ is the value assigned to the ‘ input signal high ’ parameter (see
section 13.4) (for example: ‘ Prct 23.5 ’).
• select ‘ Excitation voltage ’ ( EX.V ) to read the value of the excitation
voltage received by the load cell. This value is read from the ‘ sense ’
terminals (see section 7.2) (for example : ‘ ExV 4.97 ’).
• select ‘ Excitation current ’ ( EX.MA ) to read the value of the current
provided through the excitation voltage terminals (for example: ‘ ExMA 14.3 ’).

At the ‘ Field correction ’ ( F.cor ) menu, there is access to the ‘ field
correction ’ functions. The ‘ field correction ’ functions allow to modify
the ‘ input signal low ’ and ‘ input signal high ’ parameters of the ‘ Advanced
scaling ’ menu (see section 13.4), based on the actual input signal
measured at the input. Functions used to correct and fine tune the
slope of the load cell, by loading low and high weights and applying the
correction low and high. Tares can are applied after the correction.
• select the ‘ Field correction low ’ ( Fc.Lo ) function to set the actual
input signal value at the ‘ input signal low ’ parameter of the ‘ Advanced
scaling ’ menu. While measuring the value, the message ‘ ok ’ remains
flashing for 5 seconds. When the measure is completed, the instrument
returns to the ‘ Field correction low ’ ( Fc.Lo ) parameter.
• select the ‘ Field correction high ’ ( Fc.hI ) function to set the actual
input signal value at the ‘ input signal high ’ parameter of the ‘ Advanced
scaling ’ menu. While measuring the value, the message ‘ ok ’ remains
flashing for 5 seconds. When the measure is completed, the instrument
returns to the ‘ Field correction high ’ ( Fc.hI ) parameter.
‘ok’ message flashes while
the ‘field correction’ function
is being applied and when
finished, the instrument
returns to previous menu
entry.

Millivolts at signal terminals (in mV)
The ‘ tare ’ value is reset to ‘0’ when a ‘ Field correction low ’
( Fc.Lo ) or ‘ Field correction high ’ ( Fc.hI ) is applied.
