CHAPTER 1: INTRODUCTION TO THE 400ES SERIES DIGITAL INDICATORS
The 400ES Series Digital Indicator is a general purpose, industrial grade weight indicator
featuring keyboard tare and stainless steel enclosure. It can readout up to 50,000 display
divisions on its 0.56” tall LED display and can supply enough current for up to 4-350load cells.
All setup parameters may be entered via the front panel keys, including calibration.
If your Model 400ES Series Digital Indicator is part of a complete floor scale or has been installed
for you, you may skip to Chapter 7 for operating instructions. Prior to using the indicator, please
read this chapter carefully and completely. Store the manual in a safe and convenient place so it
will be available if you have questions concerning the operation of the scale.
If you are an installer, the indicator's installation and wiring instructions are found in Chapter 2.
The indicator contains two main setup menus: The Setup (“F”) menu, which configures the
indicator to your weigh platform and the User (“A”) menu, which configures the serial
communication port and enables some user options. Chapter 3 gives an overview and explains
how to use the five front panel keys to maneuver and save settings in both menus. Chapters 4
and 5 explain the Setup and User Menu options, respectively. Chapter 6 covers system
calibration. Prior to installing the indicator, please read this manual carefully and completely.
Store the manual in a safe and convenient place so it will be available if you have questions
concerning the setup and operation of the scale.

Your Model 400ES Digital Indicator contains a feature that allows you to print the current date on
the print ticket. This date is not stored or updated by the instrument and must be re-entered each
day.
To enter the date to be printed using the Date Entry procedure:
1. Ensure that A6 is set to Gross/Net/Tare print mode. See Chapter 3 for more information.
2. Remove power from the indicator, then re-apply power without holding down any keys.
3. The indicator will count down from all 6’s to all 1’s then will start to display dashes across the
screen one at a time from right to left.
4. BEFORE ALL SIX DASHES ARE DISPLAYED, use the front panel numeric keys to key-in the
desired date as you want it to appear in the printout. If you do not enter the first digit of the
date in time, simply start over from Step # 2. If you make a mistake entering the date, you may
use the ZERO key as a backspace key.
5. After entering the desired date, press the NET/GROSS key to save the value. The indicator
does not check for a valid date and resumes Normal Operating Mode.

6.1 CALIBRATION OVERVIEW
The indicator is calibrated by following the procedures embedded in F16 (Zero) and F17
(Span) of the Setup Menu. Each procedure enters a value into the indicator's non-volatile
memory - F16 the zero value (deadweight) and F17 the span value (test weight). The
minimum test weight that can be used is 1% of full-scale capacity. After the two calibration
procedures are executed successfully, you should record both calibration values in Table 6-
1 using the F18 View procedure.
In the unlikely event that either value is lost while in the field, the setup menu makes
provisions for re-entering these values via F19 and F20, thus eliminating the need for re-
calibration with test weights.
NOTE: This chapter assumes that the indicator is in Setup (“F”) Menu mode. If the indicator
is not in Setup Menu mode, refer to Chapter 3 for instructions.
6.2 ZERO CALIBRATION (F16)
1. While in the Setup mode, scroll to "F 16", then scroll down once using the #2 key to
enter zero calibration menu. The display will momentarily show "C 0" followed by a
value. This value is the internal A/D count and can prove useful when trying to
troubleshoot setup problems.
2. After making sure that there are no test weights on the platform, press the ZERO key to
zero out the displayed value.
3. Press the NET/GROSS key to save the zero point value. The display will show
"EndC0" momentarily, then revert back up to F16. At this time, proceed to the F17
span calibration to complete indicator calibration.
6.3 SPAN CALIBRATION (F17)
1. While in the Setup mode, scroll to "F 17", then scroll down once using the #2 key to
enter span calibration menu.
5. The display will momentarily show "C 1" for the span calibration, followed by a value
with one flashing digit. This value will be zero with the Decimal Point parameter
selected in F10. Place the test weight on the weighing mechanism.
6. Use the front panel keys to key-in the actual test weight value. There is no need to
enter a decimal point, since it is fixed on the display. If you make a mistake, press the
ZERO key to clear your entry and start over.
4. After entering the exact value, press the NET/GROSS key to save the value.
5. If the calibration was successful, the display will show "EndC1" momentarily, then
revert back up to F17. At this time it is suggested that the calibration values be
recorded for future use (see Section 6.4).
6. If the calibration wasnot successful, one of the error messages below will appear. Take
the indicated action to correct the problem, then perform a new calibration.
"Err0" - The calibration test weight or the keyed-in weight is larger than the full capacity
of the scale. Change the calibration test weight or check the input data.
"Err1" - The calibration test weight or the keyed-in weight is smaller than 1% of the full
capacity of the scale. Change the calibration test weight or check the input data.
"Err2" - The internal resolution of the scale is not high enough to accept the calibration
value. Select a larger parameter for the Span Gain (F2). SEE APPENDIX C FOR
MORE INFORMATION.

6.4 VIEW CALIBRATION VALUES (F18)
Note: The values displayed in this procedure are valid only after a successful calibration
has been performed using F16 and F17.
1. While in the Setup mode, scroll to "F 18", then scroll down once using the #2 key to
enter View calibration menu.
2. The display will momentarily show "CAL 0" followed by a value. This value is the zero
calibration value and should be recorded in the table below. Press any key to
continue.
3. The display will momentarily show "CAL 1" followed by another value. This value is the
span calibration value and should also be recorded in the table below. Press any key
to return to upper level (F18).

6.5 KEY-IN ZERO CALIBRATION VALUE (F19)
Note: This procedure is intended for emergency use only in the case of non-volatile
memory loss. A valid zero calibration value, obtained from a successful F16
calibration procedure, must be used.
1. While in the Setup mode, scroll to "F 19", then scroll down once using the #2 key. The
display will momentarily show "ET C 0", followed by a value of zero
2. Use the front panel keys to key-in the actual zero calibration value. If you make a
mistake, press the ZERO key to clear your entry and start over.
3. After entering the exact value, press the NET/GROSS key to save the value. The
display will show "E C 0" momentarily, then revert back up to F19.
6.6 KEY-IN SPAN CALIBRATION VALUE (F20)
Note: This procedure is intended for emergency use only in the case of non-volatile
memory loss. A valid span calibration value, obtained from a successful F17
calibration procedure, must be used.
1. While in the Setup mode, scroll to "F 20", then scroll down once using the #2 key. The
display will momentarily show "ET C1", followed by value of zero.
2. Use the front panel keys to key-in the actual span calibration value. If you make a
mistake, press the ZERO key to clear your entry and start over.
3. After setting the exact value, press the NET/GROSS key to save the value.
4. If the entered value is greater than zero, the display will show "E C 1" momentarily,
then revert back up to F20. If a value of zero is entered, the indicator will briefly show
"Err 5", then revert back to the screen described above in Step # 2.
