A Quick Guide to the Use of this Instruction Manual
Your BA378C has been factory set to the requirements specified on your purchase order.
If no requirements were given, the instrument will be supplied to you with default settings i.e.
3 wire RTD input; high resolution display in °C; 4 to 20mA output corresponding to an input
and display of 0.0 to 100.0°C.
If the BA378C is set to your requirements before putting it into use you should refer to:
Section 4
Electrical System Design
Section 5
Installation
Section 2.1
Controls
If optional alarms are fitted you should also refer to Section 11.
You will also find the 'Trim' menu described in Section 7 useful if you wish to calibrate the
complete measurement loop.
If the BA378C has been supplied with default settings and you wish to change these you will
need to refer to:
Section 6
Programming and Calibration
This section explains the programme functions of the front panel push-buttons and leads you
through the various stages of programming the instrument. Among the sub-divisions of
Section 6 you will find information on setting up for:
Section 6.3
Thermocouple input
Section 6.4
Resistance thermometer input
Section 6.5
Voltage input
A word of warning:
Section 6.8 explains how you can calibrate the instrument's internal
references. It is only necessary to carry out this operation if you will be using these internal
references to calibrate the instrument display,
i.e
.
not using an external calibrator
, and then
only annual or less frequent adjustment is required.
It is not necessary to calibrate these
internal references before putting the BA378C into operation
, we've already done that for
you. For this reason the reference calibration section of the programme menu 'Cond' is
protected by an additional security code. You should only enter this section of the
programme if you are sure that you want to re-calibrate the internal references.
By following the notes in this manual you should be able to set up your BA378C without any
problem. However, if you do run into difficulties Section 9 provides some guidance on
typical problems you may find during commissioning. If you still have difficulties please
contact our Sales Department. Our Sales Engineers will be able to talk you through the
procedure.
