The Transcell Model NEPTUNE 6500 Series Checkweigher is an easy to use high speed, wash
down, stainless steel bench scale. The main function of the NEPTUNE 6500 is to compare
programmed weight readings to pre-set tolerance limits that define an ACCEPTABLE range. If
the current weight reading is within an ACCEPTABLE weight range the green TARGET LED’s
light. If the current weight reading is less then the ACCEPTABLE range the amber UNDER LED’s
light. If the current weight reading is greater then the ACCEPTABLE range the red OVER LED’s
light.
The NEPTUNE 6500 features a full numeric keyboard, storage for up to 100 individual
OVER/UNDER/TARGET/TARE values with an easy link to individual ID recall. The NEPTUNE
6500 also features a simple programmable print format. Utilizing 3-5volt TTL outputs you can
readily send out check weight results to a PC or control other external devices. The NEPTUNE
6500 is available in two platform sizes and four avoirdupois weight capacities.
If you are an installer, the scale’s installation and wiring instructions are found in Appendix D. The
scale contains two main setup menus: Front panel access is available for simple calibration and

CHAPTER 4: ADVANCED FEATURES AND OPERATION
4.1 ITEM ID STORAGE
Your scale can store UNDER/OVER//TARE/UNIT information for up to 100 items. These
items are stored and retrieved under a Product ID number. The ID numbers are assigned
by the scale operator. Each ID record may contain:
·UNDER tolerance value
·OVER tolerance value
·TARE value
·Product ID number –up to 6 numeric characters

3. Enter the Product ID number and press ID to save changes.

Neptune 6500
15
4.2 TTL SET POINT OUTPUTS
This function works utilizing three 5Volt TTL outputs and allows your scale to work within a
specialized system. This is useful if you are filling individual containers to a pre-determined
TARGET weight value, or if you are check weighing individual portions, you can utilize the
set points to activate an internal buzzer that will sound when the TARGET set point is
reached.
Each output is an open-collector circuit, capable of sinking 250mA when ON. All logic levels
are active low. The circuits include +-5 V resistors to drive TTL or 5 V CMOS logic without
additional hardware.
4.2.1 SETPOINT OUTPUTS
The Neptune 6500 has three annunciators on the front display to indicate UNDER,
ACCEPT or OVER. If you want to use an external device to signal the check weigh
condition, use the external TTL outputs. The same condition that drives the internal
annunciators will drive the external device. Setup step F15 allows control over external set
point number 2. A value of 0 (zero) will cause the set point to remain high when the
condition is met. You may enter a value of 1/10s of a second to cause SP2 to alternate high
and low when the condition is met. An common example of how this delay is used would be
to flash a light on and off when the accept condition is met. Over and under would show a
steady light.
SP1 SP2 SP3
On if < Min value On if >= Min value & < Max On if >= Max value
See F15 for always on or delay time
Only one set point is active at a time. When a set point is active, the others are not.

CHAPTER 5: CALIBRATION
5.1 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.
5.2 ZERO CALIBRATION (F16)
1. While in the Setup mode, scroll to "F 16", then scroll down once using the DOWN
ARROW (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. Record this value where you can find it again.
2. After making sure that there is no weight on the platform, press the ZERO key to zero
out the displayed value.
3. Press the SET key to save the zero point value. The display will show “SAVE”then
“EndC0" momentarily, then revert back up to F16. At this time, proceed to the F17
span calibration to complete indicator calibration.
5.3 SPAN CALIBRATION (F17)
1. While in the Setup mode, scroll to "F 17", then scroll down once using the DOWN
ARROW (2) 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 scale platform.
3. Use the four directional keys (shown in Figure 6-1 below) to adjust the displayed value
to the actual test weight value. Increase the flashing digit by pressing the UP ARROW
(1) key. Decrease the flashing digit by pressing the DOWN ARROW (2) key. Pressing
the LEFT ARROW (4) key or the RIGHT ARROW (5) key will change the position of
the flashing digit.
4. Place the test weight on the scale and press the SET key.
5. If the calibration was successful, the display will show SAVE, then "EndC1"
momentarily. You can now end the calibration process or proceed through a three point
calibration.
For three point calibration - the scale will momentarily show "C 2". See steps 3, 4 and
5. The scale displays C 3. See steps 3, 4 and 5.
To end as a single point calibration, press the SET key at C 2 and again at C 3. The
scale returns to F17.

Neptune 6500
17
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.
5.4 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 DOWN
ARROW (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.
3. Press DOWN ARROW (2) again. Scale 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 the up arrow key to return to upper level (F18).
