Thisbargraph featuresHakaru'sunique QUICKSET PROGRAMMING.
When a front panel button is pressed the associated function is
directly changed. The direction of change will be either up or down,
as indicated by the UP and DOWN indicator LEDs. After the indi-
cator LED lights up there is a 0.5 second delay before any change
occurs. When a button is released and pressed again the direction
of change is reversed. As there are no menu or sub-menus to navi-
gate, the programming and setup is quick and easy.

Meters with QUICKSET PROGRAMMING feature a unique, easy-to-use, two point scaling and calibration system.
Scaling or calibration is accomplished simply, by applying a zero or low input signal and adjusting the bar to the
desired reading, using the ZERO button. A higher input signal is then applied, and the bar is adjusted to the desired
reading for that input value, using the SPAN button.
IMPORTANT DETAILS THAT MAKE QUICKSET PROGRAMMING EASY TO USE AND UNDERSTAND
1. The zero and span buttons are functionally the same, except as follows: The ZERO button can initiate a scaling
with input signals from zero to 95% of fullscale.The Span button can initiate a scaling with input signals from 5%
of fullscale to 105% of fullscale.
2. When a Zero or Span button is pressed, the Up or Down indicator LED will immediately light up to show the
direction, in which the Bar will move, after a 0.5 second delay. If the button is released and pressed again, the
opposite Up or Down indicator will light up, and 0.5 seconds later the Bar will begin to move in that direction until
the button is released. When the bar is being adjusted to zero or fullscale, the bar will automatically stop at the
zero or fullscale position, and will not overshoot these positions, even if the button continues to be pressed.
3. While the bar is being adjusted, a new offset and scale factor is continuously being calculated. At the moment the
button is released, and the scaling is accepted, the calculation data is memorized and implemented. The Scaling cal-
culation is based on the new position of the Bar, the input signal being applied at that moment, and the previously
memorized position of the Bar and the input signal that was being applied, when the other button was last released.
4. Positive and negative signals maybe integrated into a two point scaling. However when either a ZERO or SPAN
button is pressed the input signal being applied, must be more than 5% higher or lower than the previously mem-
orized value of the input signal, that was being applied when the other button was last released. If not, the bar
will flash, the scaling will not be accepted, and the previous scaling will still be retained in memory.
5. Because of the requirement, that a new scaling input signal must be 5% higher or lower than the previously stored
value, it can sometimes be difficult to implement a desired scaling, particularly when using a calibrator that only
has fixed output values. In this case Reset the Scaling by pressing the ZERO and SPAN buttons simultaneously
for two seconds. Both scaling memories will be erased and an internal default scale factor will be loaded. This
provides a display of zero to fullscale on the bar for an input of approximately 0 to 100% of the range selected
on the input signal conditioning module. After Resetting the Scaling a new calibration, using either button, can
be implemented with new input signal values. It is good practice to always use the Zero button for lower input
signals and the Span button for higher input signals, even when the bar display scale is inversed.
6. The larger the difference between two points used for calibration, the better the accuracy. However if the differ-
ence is too high, and the output from the input signal conditioning module is greater than +2.1VDC, or less than
-1.05VDC, the bar will flash over range. The calibration will not then be accepted and, the previous scaling will
still be retained in memory. In this case, either a lower input signal must be used, or a higher range on the input
module should be selected to recalibrate the meter.
Note: Most input signal conditioners have provisions for analog calibration and scaling. If the meter’s scale factor
is set to read zero with a zero input (shorted input), and to read 10 Bars fullscale with a 2.000 V input, any pre-cali-
brated signal conditioner with an output that does not exceed – 1 V to + 2 V, will read correctly in the meter without
any further calibration.
STEP A REVIEW THE INPUT MODULE STATUS
1) See pages 12 – 15 for information on input modules that may be used
with this meter.
2) Confirm that the correct range and input is selected on the input signal
conditioning module.
Note: When undertaking an initial set up and primary scaling and calibration of the
meter it is best to start with a reset of the scaling.
STEP B RESET THE SCALING
1)Apply power to the meter and press the ZERO and SPAN buttons simultaneously
for 2 seconds. This erases any previously memorized scalings, and resets the scal-
ing to the factory default, of approximately zero to full scale, for an input, that is 0 to
100% of the range selected on the input signal conditioner.
Standard or Center Zero Display Mode may be selected, depending on the Operating Mode selected.
If the standard display mode is not already selected open the meter case as showing on page 4 and
move the jumper clips on the display mode select header to the OFF position.

Note: To calibrate the bargraph you must be able to input two input signals. Usually the mini-
mum input (LO Input) and the maximum input (HI Input) signals are used for optimum accuracy.
However a scaling can be accomplished with any two signals that are higher or lower than each
other by more than 5% of fullscale and are not greater than +2.1VDC or less than -1.05VDC.
STEP C SET THE LOW INPUT SIGNAL READING ON THE BAR
1) Apply the LO input signal (4 mAin this example) to the input pins.
2) Using the ZERO button adjust the bar down to the required position.
STEP D SET THE HIGH INPUT SIGNAL READING ON THE BAR
1) Apply the high input signal (20mA in this example) to the input pins.
Using the SPAN button adjust the bar to the required position.
This position could be higher or lower than the position adjusted in
Step 2. The scaling for an input of 4 to 20mA is now complete.

STEP A SELECT THE CENTER ZERO DISPLAY MODE FOR CH1
1) Following the instructions on page 4, remove the meter from the case.
2) Select the Center Zero Mode for CH1 by repositioning the jumper clip on the
Center Zero Display Mode Select Header.
STEP B REVIEW THE INPUT MODULE STATUS
1) See pages 15 – 21 for information on input modules that may be use with this meter.
2) Only the IDP4 Universal Input module can be used for dual inputs and information
on this module can be found on page 15.
3) Confirm that the correct range and input is selected on the input signal conditioning
module.
Note: When undertaking an initial set up and primary scaling and calibration of the meter it is
best to start with a reset of the scaling.
STEP C RESET THE SCALING ON CHANNEL ONE
1) Apply power to the meter and press the CH1 ZERO and CH1 SPAN buttons
simultaneously for 2 seconds. This erases any previously memorized scalings,
and resets the scaling to the factory default, of approximately zero to full scale,
for an input, that is 0 to 100% of the range selected on the input signal
conditioner.
The procedure for scaling the bar graph for bipolar signals is very simple. If say CH1 has to be scaled for -1V to +1V, the steps
are as follows:

One Point Quickset Rescaling and Calibration Procedure
Center Zero Mode Scaling For Bipolar Inputs
ONE POINT RECALIBRATION
As explained earlier, the TFL-B101Q bargraph is calibrated using two point calibration. Once a bargraph is calibrated, the
low end of the range may be then recalibrated without affecting the calibration of the high end, and
vice versa.
For example, take an TFL-B101Q that has been calibrated to read zero to full scale for an input of 4 to
20mA. If now the scaling has to be changed to read zero to full scale for an input of 0 to 20mA, only
the low (4 mA) end needs to be recalibrated. The high (20 mA) end of the scaling is left untouched,
and so does not change. The following one point recalibration procedure is used for this purpose.
STEP A RECALIBRATE THE LOW INPUT SIGNAL READING ON THE BAR
1) Apply the LO input signal (0 mA in this example) to the input pins.
The first segment will flash, indicating an under range condition.
2) Using the ZERO button adjust the bar up to the required position.
3) The TFL-B101Q has now been recalibrated to read zero to fullscale
for a 0 to 20 mA input.

STEP D SET THE LOW INPUT SIGNAL READING ON THE BAR
1) Apply the LO input signal (-1V in this example) to the CH1 input pins.
2) Using the CH1 ZERO button adjust the bar down to the required position. In
this case, all the bar segments from mid point down to the bottom will be ON.
STEP E SET THE HIGH INPUT SIGNAL READING ON THE BAR
1) Apply the high input signal (+1V in this example) to the CH1 input pins.
2) Using the CH1 SPAN button adjust the bar to the required position. This
position could be higher or lower than the position adjusted in Step 2. In this
case, all the bar segments from mid point up to the top will be ON.
3) The scaling of CH1 for an input of -1V to +1V is now complete.
Center Zero Mode Scaling For Bipolar Inputs continued
Setpoint Adjust
The bargraph has the option to have up to 4 setpoints (two 10A Form C relays and two 5A Form A relays) installed. Each relay may
be set to activate either above or below its setpoint by inserting jumper clips on the Relay Activation header which is located on the
Display Driver Board. See the layout diagram on Page 4 and 14 for the exact location. The steps to setup the setpoints are as follows:
1) SELECT THE RELAY ACTIVATION MODE FOR EACH INSTALLED RELAY
Make sure that the required relays have been installed in the meter. Refer to the component layout on Page 14 for relay
positions. If a jumper clip is installed in a specific relay position on the Relay Activation Mode Header, that relay will acti-
vate when the display bar is lower that the programmed setpoint. If no jumper clip is installed in a specific relay position
on the Relay Activation Mode Header, that relay will activate when the display bar is equal to or higher than the pro-
grammed setpoint. The Diagrams below show some of the various possibilities for relay activation.
Default
SP1, SP2, SP3, and SP4 all activate when input is equal to or higher than set point.
SP2 and SP4 activate when input is lower than set point. SP1 and SP3 activate when
input is equal to or higher than set point.

2) ADJUST THE SETPOINT FOR EACH RELAY
The setpoint for each relay is set by the front panel buttons marked SP1, SP2, SP3 and
SP4. When a front panel button is pressed and held down, the associated setpoint is direct-
ly changed. The direction of change will be either up or down, as indicated by the UP and
DOWN indicator LEDs. After the indicator LED lights up there is a 0.5 second delay before
any change occurs. To reverse the direction of change, release the button and then press
down again. As there are no menus or sub-menus to navigate, the programming and setup
is quick and easy.
Setpoints are indicated on the bar display by an ON segment if the bar is below the set-
point and with an OFF segment if the bar display is above the setpoint.

To comply with the latest safety requirements, the tri-color bargraph is designed like a traffic
light, to display either red, orange or green, but only one color at a time. When the bar reaches a
selected color change point, the entire bar will change to the color designated for that zone. This
eliminates any ambiguity as to the signal status, especially just after transitioning to a new zone.
However, if two or more setpoints with differently specified colors are positioned at the same
set point value, the color specified for the set point with the highest identifying number will be
displayed. When set points are set to the same value, the SP4 color overrides the SP3 color, the
SP3 color overrides the SP2 color, and the SP2 color overrides the SP1 color.
STEP A ENTER COLOR SET MODE
Hold down ALL four setpoint buttons (SP1, SP2, SP3 and SP4) and apply power to the
meter. The meter will light up in the Color Set Mode. Release all the setpoint buttons.
STEP B SELECT COLOR FOR BAR ABOVE SETPOINT 1
Hold down the SP1 button. The color of the bar segments below SP1 will cycle between red,
green and orange. Release the SP1 button when the bar is the required color. Now
Whenever the bar is above the SP1 level it will be this color. When the bar is below the SP1
level it will always be red.
STEP C SELECT COLOR FOR BAR ABOVE SETPOINT 2
Hold down the SP2 button. The color of the bar segments below SP2 will cycle between red,
green and orange. Release the SP2 button when the bar is the required color. Now
whenever the bar is above the SP2 level it will be this color.
STEP D SELECT COLOR FOR BAR ABOVE SETPOINT 3
Hold down the SP3 button. The color of the bar segments below SP3 will cycle between red,
green and orange. Release the SP3 button when the bar is the required color. Now
whenever the bar is above the SP3 level it will be this color.
STEP E SELECT COLOR FOR BAR ABOVE SETPOINT 4
Hold down the SP4 button. The color of the bar segments below SP4 will cycle between red,
green and orange. Release the SP4 button when the bar is the required color. Now
whenever the bar is above the SP4 level it will be this color.
STEP F EXIT COLOR SET MODE
Turn off the power to the meter for 5 seconds and then reapply the power. The bargraph will now work with the programmed colors.

To calibrate the Analog Output you must be able to input two input signals. Usually the minimum
input (LO Input) and the maximum (HI Input) signals are used for maximum accuracy.
For example the five steps to obtain an Analog Output of 4mA to 20mA for an input of
0 to 10V are:
STEP A ACCESS THE ANALOG CALIBRATION MODE
1) Confirm the internal analog output module is installed and that the required
voltage or current output option is selected.
2) Turn OFF the power to the bargraph.
3) Hold down the ZERO and SPAN buttons simultaneously and re-power the
bargraph. The ZERO button will now function as the LO button and the SPAN
button will now function as the HI button for calibrating the Analog Output.
STEP B RESET THE ANALOG OUTPUT SCALING
1) Press the LO and HI buttons simultaneously and hold them down for 2
seconds. This will reset the analog output scaling to the default value. The
default analog output scaling is approximately 0 to 20mA (0 to 10V if volt-
age output option is selected) for an input that is 0 to 100% of the range
selected on the input signal conditioner.
STEP C CALIBRATE ANALOG OUTPUT FOR LO SIGNAL
1) Apply the low input signal (0V in this example) to the meter.
2) Connect an external multimeter to the analog output pins (Pins 17 and 18).
3) Using the LO button adjust the analog output as measured on the external
multimeter to be the required value. (4mA in this example). When the LO
button is pressed, the UP or DOWN indicator LED shows the direction of
change. To reverse the direction of change release the LO button and press
down again. Initially the output changes very slowly, but speeds up as the
LO button remains pressed down. The analog output for a low input can be
set in this step to any value in the range of 0 to 20mA or 0 to 10V ( if the
voltage output option is selected).
STEP D CALIBRATE ANALOG OUTPUT FOR HI SIGNAL
1) Next apply the high input signal (10V in this example) to the meter.
2) Using the HI button, adjust the analog output as measured on the external
multimeter to be the required value. (20mA in this example). When the HI
button is pressed the UP or DOWN indicator LED shows the direction of
change. Release the HI button and press again to reverse the direction of
change. Initially the output changes very slowly, but speeds up as the HI
button continues to remain pressed. This output may be higher or lower
than the value set in Step 2, and may be any value in the range of 0 to 20mA
or 0 to10V. This allows the easy reversal of analog output that is required
in some applications.
STEP E EXIT THE ANALOG OUTPUT CALIBRATION MODE
1) Turn OFF the power to the bargraph
2) Re-power the bargraph. The two buttons will now return to their original
function of DISPLAY 2 ZERO and DISPLAY 2 SPAN.
3) Calibration is now complete and the bar is scaled for a 0 to 10V input to
produce an analog output of 4 to 20mA.

When the optional analog output module is installed, an independently calibrated 16 bit isolated, voltage or current analog output is
available. The analog signal is independently scaled to the input signal and not to the bargraph display. It is important to note that the
Analog Output is completely independently of the bargraph display. This means for example that the bargraph display may be scaled
to go from zero to full scale as the input changes from 0 to 5V, while at the same time, the analog output is scaled to go from 4 to 20mA
as the input changes from 2 to 3V. Rescaling the bargraph or the analog output will not affect the scaling of the other.
