6~3 Sensor wiring (continued)
General –the instrument is designed to be directly attached to the
sensor probe assembly. Remote Probes may be used but the user
must ensure all sensor entries maintain environmental protection to
at least IP65 rating. To comply with CE EMC requirements the
sensor wires should be no longer than 3 metres. When using an
RTD, for best results we recommend using three-wire connection;
this method compensates for any lead resistance between the
sensing element and instrument. Two-wire RTD connection is
possible by linking pins 1 and 3: refer to Figure 3.
Thermocouple wire type must be maintained from the sensor
element to the instrument terminals. The terminals are effectively
the cold junction point and can be displayed as “Tamb” ambient
temperature.

and offset.
Single press, in display mode to enter the menu lists.
The configuration settings are presented as a series of menu lists.
A single press (click) from display mode is used to enter the
configuration menu lists.
The order of the menu lists options is as follows:
•Sensor type.
•Display unit.
•Decimal place.
•Response time.
•Offset.
•Pass code.
Long Press > 2 seconds, in configuration mode
To advance through the menu option lists, press continuously for
over 2 seconds. This action is used to advance to the next option
in the menu list and to confirm a selection, and when a variable
has been selected.
Single press and Double press, in configuration mode
A single press (click) from configuration mode. This action steps
through the selected menu list variable, e.g. sensor menu list
variable = Pt100 Eu, single press will select Pt100 US. A double
press steps through the list in reverse order.
No press > 12 seconds, in configuration mode
To escape from the configuration menu, allow a period of 12
seconds with no button action.
Alternatively, stepping through the menu list options will return the
device to the run mode.
