5 INPUT HEADER ADJUSTMENT
The analog input board for the TEX-BAR has a header which can be set to 3 positions,
depending on your input type and range, as per the table below:
Header Position Used For
20mA 0–20mA and 4–20mA input ranges (default setting)
2V 0–2V input range
10V 0–10V input range
5.1 - Do I need to shi the input header?
In most cases the input header does not need to be changed from its default posi-
tion of '20mA' (suitable for 0–20mA and 4–20mA inputs).
You will need to shift the input header if:
›You are using the 0–2V or 0–10V input range, or
›You are changing your input type or range from a previous setup
5.2 - How to shi the input header
A If the meter is already installed, remove it from the panel, and unplug all plugs
from the back of the unit.
B Using a small screwdriver or similar implement,
press downward into one of the slots at the
rear of the case.
This will disengage the tab which holds the
back plate on, allowing it to be gently
levered away at one corner.
C Holding the loosened corner open
with one hand, disengage the le-
ver on the opposite slot.

TEX-BAR-MAN-15V05 (0903)Copyright © 2015 Dene Instruments

D You should now be able to remove
the back plate. If it does not unclip
easily, you may need to disengage
the two remaining tabs by repeat-
ing steps 5.2B–C on the other side
of the meter.
E Slide the analog input module out
of the meter case. (See 3.1A to
identify the input module.)
F Position the header on the input
module as required for your input

Note that you will also need to change the Input Mode in soware from the front
panel - see 6.2C.
G Slide the input module back into the meter case.
Make sure that it is sitting in the tracks on the le and right. Press rmly until the input module
is fully inserted and sits ush with the other boards that are visible from the back of the meter.
H Replace the back plate.
Begin by inserting the two lower tabs into the slots, and then position the upper tabs so that
they will not catch on the top lip of the meter case. Apply rm pressure until the back plate
clicks into place.
I Reconnect the plugs and return the meter to the panel installation.
Don't forget that once the unit is connected and powered up, you will need to
enter the Input Setup menu (6.2) and conrm that the correct Input Mode is
also selected (see 6.2C).

6 INPUT SETUP & CALIBRATION
6.1 - Enter F1 PIN number
A Enter the calibration mode by pressing the button.
_ _ _ ENTER CAL PIN NUMBER scrolls across the display and toggles with 0.
Use the and buttons to enter your security code (factory default 1). Then
press . If the correct PIN is entered, setup is started at 6.2.
If an incorrect PIN number is entered, _ _ _ INCORRECT PIN NUMBER – ACCESS
DENIED scrolls across the display and it returns to normal operating mode.
You will have the opportunity to change your PIN number at the end of this section
(6.8). If you have forgotten your PIN number, see Section 9.
6.2 - Input setup
A _ _ _ INPUT SETUP scrolls across the display and toggles with SKIP. Press to
skip to 6.3, or the button and then to ENTER input setup.
B _ _ _ MAINS FREQUENCY scrolls across the display. Use the and buttons
to select 50HZ or 60HZ, and then press .
C _ _ _ INPUT MODE scrolls across the display and toggles with the current selec-
tion. Use the and buttons to select: 4–20 (4–20mA), 0–20 (0–20mA),
2V (0–2V) or 10V (0–10V). Then press .
Note that if you change the INPUT MODE in this step, then the input header on the analog
input module may also need to be changed. See Section 5 for more information.
D _ _ _ DECIMAL POINT POSITION scrolls across the display and toggles with the
current selection. Use the and buttons to select NO DP, 0.1, 0.12, 0.123,
or 0.1234, and then press to accept and continue.
E _ _ _ DISPLAY ROUNDING scrolls across the display and toggles with the select-
ed rounding. Using the and buttons, select: NONE, 2, 5, or 10. Press .

TEX-BAR-MAN-15V05 (0903)Copyright © 2015 Dene Instruments
13
Rounding is quoted in display counts and is not inuenced by decimal point position. For ex-
ample, if your input signal is 5.3mA, the display will show: 5.3 (for rounding=NONE), 5.4 (for
rounding=2), 5.5 (for rounding=5), or 5.0 (for rounding=10).
6.3 - Calibration
A _ _ _ CALIBRATION TECHNIQUE scrolls across the display and toggles with
SKIP. Press to skip to 6.4, or use the and buttons to select a calibra-
tion method: AUTO, MAN (manual), or S.G. (specic gravity). Then press .
If you selected AUTO, complete steps 6.3B–D now.
If you selected MAN, complete steps 6.3E–F now.
If you selected S.G., complete step 6.3G now.
If you selected SKIP, skip to 6.4 now.
AUTO (key-in) calibration uses zero and span values to calculate the scale and oset. This is the
most accurate calibration method, but requires known low and high input signals (or the use
of a calibrator).
MAN The manual calibration procedure uses low and high display values, and is intended for
a pre-calibrated sensor with a known output range. (For example 4mA=0 and 20mA=1000.) It
does not require any input signals to be applied to the controller during calibration.
S.G. - The specic gravity calibration procedure allows the user to enter a scale factor which is
used to compensate for changes in the specic gravity of dierent substances.
NOTE THAT THIS DOES NOT CONSTITUTE A FULL CALIBRATION, AND ASSUMES THAT
EITHER AN AUTO OR MANUAL CALIBRATION HAS BEEN APPLIED PREVIOUSLY WITH THE
S.G. VALUE SET TO 1.0.
Auto calibration
B _ _ _ APPLY LOW INPUT SIGNAL – – – –ENTER LOW DISPLAY VALUE scrolls
across and toggles with the current selection. Apply the required low input sig-
nal, and wait a moment for the signal to stabilise. Then, using the and
buttons, enter your low display value, and press to accept and continue.
C _ _ _ APPLY HIGH INPUT SIGNAL – – – –ENTER HIGH DISPLAY VALUE scrolls
across and toggles with the current selection. Apply the required high input
signal, and wait a moment for the signal to stabilise. Then, using the and
buttons, enter your high display value, and press .

TEX-BAR-MAN-15V05 (0903) Copyright © 2015 Dene Instruments

D If Auto calibration was successful, you will be directed out of the calibration
menu to the operational display without viewing any further scrolling messag-
es. (To proceed to step 6.4, you must select SKIP at 6.3A.)
If calibration fails, _ _ _ CALIBRATION FAILED will scroll across the display and
you will be directed back to the operational display. The most likely cause of this
error is that the controller could not detect any change in input signal during
calibration. Check your signal and connections, and repeat the procedure.
Manual calibration
E _ _ _ ENTER DISPLAY VALUE FOR [LOW MA/V] scrolls across the display, and
toggles with the current low display value. Use the and buttons to adjust
the display value for the low level input signal. Then press .
The text string for [LOW MA/V] is determined by your INPUT MODE (selected in 6.2C):
0MA (for 0-20mA), 4MA (for 4-20mA) or 0V (for 0-2V/0-10V).
F _ _ _ ENTER DISPLAY VALUE FOR [HIGH MA/V] scrolls across the display, and
toggles with the current high display value. Use the and buttons to adjust
the display value for the high level input signal. Then press .
The text string for [HIGH MA/V] is determined by your INPUT MODE (selected in 6.2C):
20MA (for 0/4-20mA), 2V (for 0-2V) or 10V (for 0-10V).
Manual calibration is now complete. You will be directed back to the opera-
tional display. (To proceed to step 6.4, you must select SKIP at 6.3A.)
Specic gravity scale factor
G _ _ _ SPECIFIC GRAVITY scrolls across the display, and toggles with the specic
gravity scale factor. Use the and buttons to adjust this value as required,
and then press .
Specic gravity scaling now complete. You will be directed back to the opera-
tional display. (To proceed to step 6.4, you must select SKIP at 6.3A.)
Note that altering the SPECIFIC GRAVITY scale factor does not constitute a
full calibration, and assumes that either AUTO or MAN calibration has been
applied previously with the S.G. value set to 1.0.

6.4 - Averaging
Your controller has input signal averag-
ing, optimising stable measurement.
If the change in input exceeds the
averaging window value it will not
average, ensuring fast response when
there are large dierences between
readings.

A _ _ _ AVERAGING PARAMETERS scrolls across and toggles with SKIP. Press
to skip to 6.5, or the button and then to ENTER averaging setup.
B _ _ _ AVE SAMPLES scrolls across the display and toggles with the currently
selected averaging. Using the and buttons, alter the number of input
samples that the controller will average, and then press .
Increasing the number of samples will stabilise measurement, but it will also slow down re-
sponse rates. A typical value is 4.
C _ _ _ AVE WINDOW scrolls across the display and toggles with the currently
selected averaging window value. Using the and buttons, alter the signal
averaging window. Then press .
If your input signal contains large noise spikes, you can increase the size of the averaging win-
dow to ensure that these are still averaged. However, increasing the window size too far will
reduce the ability of the controller to respond quickly to real changes in input signal. Setting
AVE WINDOW to 0will give continuous averaging as per the selected averaging samples. A
typical value is 10% of your system capacity.
6.5 - Analog output setup
A _ _ _ ANALOG OUTPUT SETUP scrolls across the display and toggles with SKIP.
If your controller does not have analog output installed, (or you do not wish to
congure your analog output now), press to skip to 6.6.
