13. Configuration menu
13.1 Function codes
The fastest way to configure the instrument, is to select a predefined
configuration code
(see section 8)
. At the ‘ Configuration code ’ ( codE )
parameter use keys ‘ UP ’ (
5
) and ‘ LE ’ (
3
) to move up and down
through the list of codes. Locate the desired code, and press ‘ SQ ’ (
<
).
The instrument shows the ‘ codE ’ parameter. Press ‘ LE ’ (
3
) to exit the
‘ configuration menu ’. The instrument stores the new configuration,
applies a ‘ power-up ’ routine and returns to the ‘ normal mode ’ of operation
(see section 10.2).
Selecting a ‘
reserved ’ code or ‘ ---- ’ returns to the previous menu without
changes.
When entering the ‘
Function code ’ ( codE ) parameter, the active
‘ configuration code ’ is displayed. If the actual configuration does not
match any of the configuration codes, code ‘ uSEr ’ is displayed.
There are different codes for 4/20 mA output (codes from 010 to 099)
and 0/10 Vdc output (codes from 110 to 199) (see section 8).
Custom input and output signal ranges can be configured at the
‘ Advanced scaling ’ section of the ‘ configuration menu ’ (see section 13.6).
Configuration code
Enter the code (see Table 2)
13.2 Input range
At the ‘ Input signal ’ ( InP ) menu entry, select the input signal to be
measured. The different input signals available are grouped by process,
thermocouples, pt sensors, ntc sensors, resistances and potentiometers.
Only one input signal can be selected.
If you have already selected a configuration code (see section
13.1), the input signal has been already selected and there is no
need to manually select the ‘ Input range ’ ( InP ) parameter again.
At the ‘ Process ’ ( Proc ) parameter select ‘ 420 ’ for 4/20 mA or ‘ 010 ’ for
0/10 Vdc signal input.
At the ‘
Thermocouples ’ ( tc ) parameter select from the available
thermocouples J, K, N, E, T, R, S, C or B.
At the ‘
Pt sensors ’ ( Pt ) parameter select from the available pt sensors
Pt100 (2 wires or 3 wires), Pt500 or Pt1000. For 2 and 3 wires Pt100
sensors, see section
11.6
for differences on connection for each case.
At the ‘ Ntc sensors 1 ’ ( ntc.1 ) parameter select from the available Ntc
sensors. The decimal point at the beginning indicates that part of ntc
name is missing. For example, the ‘ Ntc 44004 ’ is designated with ‘ .4004 ’
as the first number ‘4’ is missing. The same applies to Ntc sensors
44004 to 44009 and 44030 to 44034. For non-standard Ntc sensors,
characterized for R
25
and ß parameters, see the the ‘ Ntc sensors 2 ’
( ntc.2 ) parameter below.
At the ‘ Ntc sensors 2 ’ ( ntc.2 ) configure the input to read from an ntc
sensor, characterized by the R
25
and ß parameters. At the ‘ Ntc R
25
’ ( r.25 )
parameter configure the resistance at 25 degrees of the ntc sensor, in
KOhms, with accepted values from 1.0 KOhms and 200.0 KOhms. At the
‘ Ntc ß ’ ( BEtA ) parameter configure the value fo the ‘ß ’ parameter of the
ntc sensor, with accepted values between 2000 and 5500.
At the ‘
Resistances ’ ( rES ) parameter select from the available resistance
ranges.
At the ‘ Potentiometer ’ ( Pot ) parameter select to activate the
potentiometer mode.
At the ‘ Passive Potentiometer ’ ( Pot.P ) parameter select to activate
the passive potentiometer mode. See section
11.2
for an explanation of
differences between potentiometer and passive potentiometer measure.
