Set Calibration Table
This is a calibration function which utilizes a table of values to achieve a linear indication, when a non-linear set of
signal values defines the process being measured. If this prompt is visible, the ZERO and FULL calibration methods
will no longer function and calibration must be performed in accordance with section 3.2.
This function will be neither displayed nor active if it has not been enabled at the factory. The function may be enabled
in the field however, it requires opening the case and removing the instrument internals in order to access a jumper
which is located on the CPU module. Field enabling of the table function will erase any previously entered
configuration settings and may void the instrument’s warranty. Consult the sales office for authorization to perform
enabling of the table function prior to performing this action.
Enabling the Table function in the Field
CAUTION! ESD sensitive components are employed on the modules of the instruments internals. Before attempting
this operation, insure that ESD mitigation practice has been employed
1.
Remove the cover and the three screws that retain the instrument internals.
2.
Slide the internals out of the case.
3.
The enabling jumper is to be installed permanently across two pins on the CPU module. The CPU module is
located immediately behind the display module.
4.
Install the jumper in the location shown in the photo below.
5.
Insert the instrument internals into the case and reinstall the three screws removed in
step 1. Do not install the cover at this time.
6.
Install a jumper across JA1 pins 1 and 2 on the display module.
7.
Power up the instrument and allow it to reinitialize. The previous configuration is erased
and factory defaults are now in effect.
8.
Remove the JA1 jumper and reinstall the cover. Configure the instrument.
When the table menu is entered, selection of the number of table points and population of
the table values is performed by following the procedure in section 3.2.

Set Analog Retransmit
Zero Value
This function determines what the output current will be when the display that the retransmit is tracking (numeric or
bar) is at its zero scale point. The zero scale point of the numeric display is set by selecting
when setting
BarGraph zero (
). The zero scale point of the bar display is set by selecting
when setting Bar zero
(
.
)
The output values can be set to any value between 0 and 20 mADC in 0.001 mA steps.
•
Press the ENTER / SAVE button when the A . ZERO prompt appears. The present analog zero value will be
displayed.
•
Press the increase or decrease button to increase or decrease the value. If the button is held the displayed values
will change at a faster rate.
•
To save the new value, press the ENTER / SAVE BUTTON.
