T
he table is explained in the Chapter 8 reference guide section: “Temperature
Sensors, Units and Display” (p.17). Press reset to reset recorded high / low
temperatures, or press done to return to the measurement screen.
3.5 Ultrasonic Echo Conditions
N
avigate to the dB symbol and press enter (+). You will be presented with the
m
easured echo amplitude and the maximum amplitude available. The amplitudes
a
re presented in dB relative to a system threshold amplitude. Echo amplitude
should be above threshold amplitude for reliable measurement. Echo strength
between 3 dB and 8 dB (maximum) is reliable. Echo amplitude refers to the echo
measured just prior to navigating through the toolbar. Press done to return to the
measurement screen.

.6 Product Identification Details
F
rom the measurement screen, navigate to the ID symbol on the toolbar and press
Enter (+). Product information will be displayed: serial number and part number.
Press Back to return to the measurement screen or navigate to one of the options:
Software Information (SW), Hardware Information (HW), or Manufacturing Date
Information (Date). SW screen will display firmware versions of the embedded
a
pplication and of the embedded boot-loader. Press Back to return to the previous
m
enu. HW screen will display product information regarding sensor type and model
t
ype. Press Back to return to the previous menu. Date screen will present the date

4. Quick Setup
Set ULTM for operation by a quick 7-step wizard-driven procedure using the basic
menu option.
Note: Configuration using the display and keypad supports metric units only. For
English units, use the PC configuration method as described in the Chapter 5
describing Configuration with a PC (p.9).
A. Turn on ULTM and wait for the measurement screen to show up. Navigate
through the toolbar and select setup.
B. Scroll and select Basic Setup from the Main Menu.
C. Scroll and select application (Low power or High power). For additional details
about the application type refer to the reference guide under Chapter 8:
“Application Type” (p.15).
D. Determine distance to empty level. For additional details about the empty level,
see the reference guide section Chapter 8: “Application Dimensions and
Constraints” (p.14). When you are done press Done.
E. Determine distance to the full level. For additional details about the full level, see
the reference guide section Chapter 8: “Application Dimensions and
Constraints” (p.14). When you are done press Done.
F. Scroll and select value to display. For additional details about value-to-display,
see the reference guide section: Chapter 8: “Distance Units and Value to
Display” (p.15).
G. Skip or perform false echo search. See the section “False Echo Scan” in
Chapter 8, the reference guide chapter (p.16).
5. False Echo Scan
Perform a false echo scan when obstructions are nearby the target or sensor.
Preferably, false echo scan should be performed when the tank is empty. If you
choose to perform false echo scan, wait for about a minute and then you will be
presented with a list of echoes.
Scroll through the listed echoes and press Enter (+) on each echo you would like
to ignore during measurement. Each such echo will be designated by a √ sign. The
number of selected echoes is presented on the top-right edge of the screen. Press
Save to store your selection and Next to proceed to the next sub-menu. To un-
s
elect an echo, scroll to that echo and press Enter (+) again. If you choose to
p
erform false echo scan a second time, new echoes which were not identified
d
uring the first scan will be reported as “new”.
The ULTM is now ready for measurements.
Parameters which are not determined during quick setup procedure will take their
d
efault value and may be modified later using the Advanced Setup menu.

. Advanced Settings
U
LTM supports a set of advanced settings. These settings are classified under
t
hree categories: GSM, Algorithm and Device state. The following items may be
modified under each category:
To execute any of the advanced settings, follow these steps: Turn ON ULTM and
wait for the Measurement screen to show up. Navigate and select Setup. Then
scroll and select Advanced Setup from the Main Menu. Now select the required
category (GSM, Algorithm or Device state) and follow the screen instructions.
When done, scroll and press **back** to return to the Main Menu, then scroll and
select the measurement display.
Each item may either present a selection of sub-items to choose from or may
require entry of a numeric field.
7. Settings Available in PC Configuration Only
Some advanced settings are available in a PC configuration only and cannot be
configured with the display/keypad. These settings are defined in the following
