At the bottom of the Live Graph screen, you have the option to either allow the
app to automatically scale the Y-axis, or set the parameters on your own. Auto­Scaling allows you to always see your data line, on the screen. To manually set
the y-axis scaling, simply un-check the box labeled “Y-Axis Auto Scaling”, and
enter the preferred values.

You can record the live data directly from this screen. At the bottom half of the
Live Graph screen, hit the “Start Logging” button. The data will be logged to the
smartphone/tablet. While logging, the top left of your screen will show “REC”
as a reminder.

NOTE:

For locally logged data, the log file’s first record will be one time
constant behind the time printed in the file name. For example,
for logging at 1 sample per 30 seconds starting at 1:00:00, the
first entry in the .csv file would be 1:00:30.

4.2.3 Gauge Format

The gauge format displays readings by pointing at the current value on a dial.
As the value changes, the dial will move either left or right to point towards the
new number. The value is also displayed in digital format at the bottom of the
gauge.

For UWBT-RH models, there are two gauges on the screen. The gauge on the
right displays the relative humidity (in percentages), and the gauge on the left
displays the ambient temperature (in the units selected in the settings menu).

For UWBT-pH models, there are two gauges on the screen. The gauge on the
right displays the pH value, and the gauge on the left displays the solution
temperature (in the units selected in the settings menu).

On the inner perimeter of the gauge, there is a bar that goes from blue to green
to red; these areas represent the values that are the low alarm, normal, and high
alarm readings, respectively. If the values exceed the high alarm, their digital
reading will show in red; if the values go lower than the low alarm, their digital
reading will show in blue. If an alarm sound has been selected, the sound will
be activated when the current value goes above the high alarm, or below the low
alarm.

The range of the gauge is set automatically; you cannot change the numbers on
the perimeter of the gauge.

When connected to multiple UWBT transmitters, you can select which
transmitter you are viewing directly from the current display screen. Click
on the button labeled “Transmitter 1” or so on, and you can view the selected
transmitter’s data.

Temperature Deadband

Deadband is the range through which the sensor reading can vary without
prompting a change in alarm state. Once the sensor reaches a high or low
alarm state, the alarm stays active until the reading reaches a value of either
“high alarm value – deadband value” or “low alarm value + deadband value”.
Temperature deadband is always a positive number. Below are examples of
deadband settings for temperature transmitters:

1. High alarm state - If you set the temperature deadband to 10°F and the high alarm

value to 250°F, the device will be in a high alarm state (red LED blinks 2 times every 2
seconds) when the temperature measurement reaches 250°F or above. The device will
stay in the alarm state until the temperature measurement reaches 240°F or below
(“high alarm value – deadband value”, which is 250°F - 10°F).

2. Low alarm state - If you set the temperature deadband to 10°F and the low alarm

value to 50°F, the device will be in a low alarm state (red LED blinks 2 times every
2 seconds) when the temperature measurement reaches 50°F or below. The device
will stay in the alarm state until the temperature measurement reaches 60°F or above
(“low alarm value + deadband value”, which is 50°F + 10°F).

to create high and low alarm hysteresis for RH. The following are examples of
deadband settings for RH/Temp transmitters:

1. High alarm state - If you set the RH deadband to 5% and the high alarm value

to 90%, the device will be in a high alarm state (red LED blinks 2 times every
2 seconds) when the RH measurement reaches 90% or above. The device will
stay in the alarm state until the RH measurement reaches 85% or below (“high
alarm value – deadband value”).

2. Low alarm state - If you set the RH deadband to 5% and the low alarm value

to 20%, the device will be in a low alarm state (red LED blinks 2 times every
2 seconds) when the RH measurement reaches 20% or below. The device will
stay in the alarm state until the RH measurement reaches 25% or above (“low

Live Transmitter Data

The live graph shows data as it is being captured by the transmitter. The
measurement value is shown with a white line. For RH graphs, the temperature
is shown with a white line (left Y-axis), and the RH percentage is shown with a
green line (right Y-axis).

The high alarm value is displayed with a constant red line. The low alarm value
is displayed with a constant blue line. If an alarm sound has been selected, the
sound will be activated when the current value goes above the high alarm line,
or below the low alarm line.

When connected to multiple UWBT transmitters, you can select which
transmitter you are viewing directly from the current display screen. Click on
the button labeled “Transmitter 1” and so on, and you can view the selected
transmitter’s data.

At the bottom of the Live Graph screen, you have the option to either allow the
app to automatically scale the Y-axis, or set the parameters on your own. Auto­Scaling allows you to always see your data line, on the screen. To manually set
the y-axis scaling, simply un-check the box labeled “Y-Axis Auto Scaling”, and
enter the preferred values.

You can record the live data directly from this screen. At the bottom half of the

5.2.3 Gauge Format

The gauge format displays readings by pointing at the current value on a dial.
As the value changes, the dial will move either left or right to point towards the
new number. The value is also displayed in digital format at the bottom of the
gauge.

For UWBT-RH models, there are two gauges on the screen. The gauge on the
right displays the relative humidity (in percentages), and the gauge on the left
displays the ambient temperature (in the units selected in the settings menu).

For UWBT-pH models, there are two gauges on the screen. The gauge on the
right displays the pH value, and the gauge on the left displays the solution
temperature (in the units selected in the settings menu).

On the inner perimeter of the gauge, there is a bar that goes from blue to green
to red; these areas represent the values that are the low alarm, normal, and
high alarm readings, respectively. If the values reach or exceed the high alarm,
their digital reading will show in red; if the values reach or go lower than the
low alarm, their digital reading will show in blue. If an alarm sound has been
selected, the sound will be activated when the current value goes above the high
alarm, or below the low alarm.

The range of the gauge is set automatically; you cannot change the numbers on
the perimeter of the gauge.

When connected to multiple UWBT transmitters, you can select which
transmitter you are viewing directly from the current display screen. Click
on the button labeled “Transmitter 1” or so on, and you can view the selected

Temperature Deadband

Software Instructions (Android)

5

Deadband is the range through which the sensor reading can vary without
prompting a change in alarm state. Once the sensor reaches a high or low
alarm state, the alarm stays active until the reading reaches a value of either
“high alarm value – deadband value” or “low alarm value + deadband value”.
Temperature deadband is always a positive number. Below are examples of
deadband settings for a temperature transmitter.

High alarm state - If you set the temperature deadband to 10˚F and the high alarm
value to 250°F, the device will be in a high alarm state (red LED blinks 2 times
every 2 seconds) when the temperature measurement reaches 250°F or above.
The device will stay in the alarm state until the temperature measurement reaches
240°F or below (“high alarm value – deadband value”, which is 250°F - 10°F).

Low alarm state - If you set the temperature deadband to 10°F and the low alarm
value to 50°F, the device will be in a low alarm state (red LED blinks 2 times
every 2 seconds) when the temperature measurement reaches 50°F or below. The
device will stay in the alarm state until the temperature measurement reaches
60°F or above (“low alarm value + deadband value”, which is 50°F + 10°F).

pH High Alarm

You can set the alarm value to the highest measurable value for the pH device.
For example, the highest value you can set for pH high alarm is 14 pH.

pH Low Alarm

You can set alarm value to the lowest measurable value for the pH device. For
example, the lowest value you can set for pH low alarm is 0 pH.

pH Deadband

pH dead band value is always a positive number. Below are examples of
deadband settings for pH transmitters.

High alarm state - If you set pH deadband to 2 and the high alarm value to be
10 pH, the device will be on high alarm state (red LED blinks 2 times every 2
seconds) when pH measurement reaches 10pH or above. The device will stay in
the alarm state until the pH measurement reaches 8pH or below (“high alarm
value – deadband value”).

Low alarm state - If you set pH deadband to 2 and the low alarm value to be
7 pH, the device will be on low alarm state (red LED blinks 2 times every 2
seconds) when pH measurement reaches 7pH or below. The device will stay in
the alarm state until the pH measurement reaches 9pH or above (“low alarm
value + deadband value”).

RH High Alarm

You can set alarm value to the highest measurable RH percentage by using
custom key board entry. For example, you can only set up to 98% for RH high
alarm.

RH Low Alarm

You can set alarm value to the lowest measurable RH percentage by using
custom key board entry. For example, you can only set as low as 2% for RH low
alarm.

RH Deadband

RH dead band should always be a positive number. RH dead band is useful
to create high and low alarm hysteresis for RH. The following are examples of
deadband settings for RH/Temp transmitters:

High alarm state - If you set the RH deadband to 5% and the high alarm value
to 90%, the device will be in a high alarm state (red LED blinks 2 times every 2
seconds) when the RH measurement reaches 90% or above. The device will stay
in the alarm state until the RH measurement reaches 85% or below (“high alarm
value – deadband value”).

Low alarm state - If you set the RH deadband to 5% and the low alarm value
to 20%, the device will be in a low alarm state (red LED blinks 2 times every 2
seconds) when the RH measurement reaches 20% or below. The device will stay
in the alarm state until the RH measurement reaches 25% or above (“low alarm
value + deadband value”).
