CHAPTER 1: INTRODUCTION TO THE Neptune 4500 SERIES DIGITAL INDICATORS

The Neptune 4500 Series Digital Indicator is a general purpose, industrial grade weight indicator.
All models operate identically, can readout up to 50,000 display divisions and can supply enough
current for up to 4-350Ω load cells. All setup parameters may be entered via the front panel keys,
including calibration.

If your Neptune Model 4500 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 two 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.

Neptune 4500 Page 5-3

CHAPTER 6: CALIBRATION

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 UNIT/SET 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 again to
zero out the displayed value.

3. Press the UNIT/SET 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 UNIT/SET key to
enter span calibration menu.

2. 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.

3. Use the directional keys (shown in Figure 6-1 below) to adjust the displayed value to the actual
test weight value. Change the flashing digit by pressing the UNIT/SET key. Pressing the ZERO
key will change the position of the flashing digit.

Neptune 4500 Page 6-1

Figure 6-1: Setup Menu Key Assignments

4. After setting the exact value, press and hold the UNIT/SET key for three seconds 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 was not 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 adjusted 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 adjusted 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.

Neptune 4500 Page 6-2

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 UNIT/SET 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

CHAPTER 7: OPERATION

7 .1 DISPLAY

As mentioned in Chapter 1, some models utilize a 6 digit LCD (Liquid Crystal Display) while others
utilize a 6-digit LED (Light Emitting Diode) display. Typically, LCD’s are used for outdoor applications
while LED’s are used indoors where brightness is needed. Table 7-1 summarizes both types of dis­play annunciators.

7.1.1 LIGHT EMITTING DIODE (LED) DISPLAY

Zero - This key sets the indicator to display zero provided the following conditions are met:

1. The indicator is displaying Gross weight.

2. The displayed weight is within the zero reset range that is programmed in F4 of the Setup
(“F”) Menu.

3. The scale is not in motion.

4 . The scale is not in overload (see Appendix D for error codes).
1 . The scale is not in overload (see Appendix D for error codes).

7.3 GENERAL SCALE OPERATION

7.3.1 WEIGHING AN ITEM

1. Select the desired weighing unit by pressing the UNIT key until that unit is indicated on
the display.

2. If necessary, press the ZERO key to obtain a weight reading of zero.

3. Place the object to be weighed on the scale’s platter and allow the weight indication to
stabilize. If the item weight exceeds the scale’s weight capacity, it displays “!!!!!!”.

4. Read the weight shown on the display.

7.3.2 ZEROING THE WEIGHT OF AN ITEM

To weigh an item in a container, the weight of that container must first be subtracted from the
overall weight to obtain an accurate weight reading.

1. Select the desired weighing unit by pressing the UNIT key until that unit is indicated on
the display.

2. Place the empty container on the scale’s platter and allow the weight indication to stabi­lize.

3. Press the ZERO key. The display shows zero weight.

4. Place the material to be weighed in the container and allow the weight indication to stabi­lize.

5. Read the weight shown on the display.

7.3.3 PIECE COUNTING

IMPORTANT NOTE: The piece counting function cannot be used in commercial (NTEP) ap-

plications.
This mode is used to indicate the number of pieces of an item you have placed on the scale’s

platform and is accessed by pressing the UNITS key. To ensure accuracy, the parts you are
counting must be consistent in weight.

The indicator uses the sampling method to determine the average piece weight (APW) of the
items you wish to count. When sampling items, always count the parts in your hand and
place them on the platform all at once. If the APW of the items is too light or the total weight
of the sample is too light, accuracy cannot be guaranteed. You will get an error message, but
piece counting will still be allowed.

1. If the items you will be counting require a container, you must first tare the container off by pressing
the ZERO key.

Neptune 4500 Page 7-3

2. Press the UNITS key until “5 0” is indicated on the display. If the screen does not show “5 0”, press
the ZERO key once. The indicator is prompting you to place five identical items on the platform.

NOTE: If you wish to change the sample number, simply press the UNITS key repeatedly until the
desired sample number appears. Available choices are 5, 10, 20, 50 and 100. If you continue to push
the UNITS key, the indicator will resort back to weighing mode and you must start again from Step 2.

3. Place the sample items on the platform all at once and allow the weight indication to stabilize. Once
this is done, press and hold the UNIT/SET for three seconds. If the sample size is large enough, the
indicator now displays the number of pieces on the platform and the “PCS” annunciator is lit. If not,
the indicator briefly displays “Lo” and automatically increments the sample size. Repeat step 3.

NOTE: If the indicator continues to display “Lo” even after sampling 100 pieces, the unit weight of the
items you wish to count is too light for your scale to process accurately.

4. To exit the piece count mode, press the UNIT/SET key.
NOTE: The APW will NOT remain in scale memory when you exit piece counting mode.

APPENDIX C: DETERMINING PROPER SPAN GAIN (F2)
C.1 SPAN GAIN OVERVIEW

The Span Gain parameter found in F2 of the Setup Menu is directly related to the ADC (Analog to
Digital Converter) integration time. This means that the lower the setting, the higher the number of
measurements per second. A span gain setting of 25 produces about 25 to 30 measurements per
second, while a span gain of 200 produces only about 3 or 4 measurements per second.

There is really no wrong setting for span gain – except in two cases. Using a low setting for a high
resolution, low output system could yield instability. Using a high setting in a high output system
could yield non-linearity.

C.2 SETTING THE INITIAL VALUE FOR SPAN GAIN

1. Determine the number of desired external graduations and choose the corresponding value
listed in Table C-1 or Table C-1a under the number closest to your full-scale input range in
millivolts.

2. Enter the Setup Menu and save this number for the Span Gain parameter in F2.

3. Perform a system calibration. If the calibration proves unsuccessful, or you wish to view the
internal counts, proceed to the next set of instructions.

C.3 VIEWING THE INTERNAL COUNTS

1. Enter the zero calibration menu (F16) and follow steps 1 to 3, but do not save the zero point.

2. After pressing ZERO to zero the offset, place the test weight(s) on the platform. The displayed
count is the internal count. If the count remains on zero, check your load cell connections.

3. At full scale, the displayed count should be a minimum of 2 times the desired external
graduations. However, for maximum stability, a ratio of 6:1 or higher is recommended.

4. If the displayed count is large enough, remove the test weight(s), re-zero the indicator if
necessary, and proceed with the calibration. If the displayed number is not large enough,
increase the Span Gain to the next highest choice in the Setup Menu and re-calibrate.
