Introduction
The TI-500 is a general purpose, "no frills" digital
indicator housed in a standard black ABS enclosure. It
comes standard with a large (.75") LCD screen for
easy readout of up to 50,000 display divisions, and
supplies enough current for up to 4-350?load cells.
All setup parameters may be entered via the front
panel keys, including calibration.
Its sister indicator, the TI-500E, features a green LED
screen for use in poorly lit areas. Function-wise the TI-
500E is the same as the TI-500.
The TI-500 has two RS-232C communication modes:
full duplex serial format forcommunication
communication with personal computers or remote
displays and a special Gross/Net/Tare mode for direct
connection to a printer. In full duplex mode, the unit
can transmit data on demand, or continuously in a
popular data protocol.
The indicator's setup parameters are altered through the
Setup menu while the serial communication
parameters are altered through the User menu The
configuration section of the manual, starting on page 2,
explains how to use the five front panel keys to
maneuver and save settings in both menus.

Installation and Wiring
Following is the Installation and Wiring directions for the standard TI-500/500E indicator only. If the
indicator was ordered in the stainless steel enclosure, please refer to Appendix D for wiring information.
The TI-500's back cover comes equipped with a
female DSUB-9 connector for the RS-232 serial port,
a male input jack for DC power, a calibration switch,
and a female 14-pin Centronics type connector for
input of the 15’ 4-wire load cell cable, included. See
below for wiring and color code information.

Configuration
The TI-500 indicator includes two separate menus
which contain all of the configurable parameters for
the unit. The Setup menu, containing most of the
indicator's functional setup parameters, consists of 15
separate menu selections, each with its own sub-menu
of choices. The User menu, containing most of the
indicator's serial communication parameters, consists
of 9 separate menu selections, each also with its own
sub-m
own sub-menu of choices.
To set up the indicator, you must first enter the
appropriate menu mode. Once there, four of the front
panel keys become directional navigators to move
around in the menus, and one key is used to save or
SET the selections. Complete directions for the
standard indicator start on the next page.

Setup/Calibration
Switch
SET
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, the user should record both
calibratio
both calibration values, which can be viewed by
entering 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.
To calibrate the zero point using the F16 zero calibration procedure:
1. If the unit is not in the Setup mode, enter the Setup mode as follows: Turn the power off to the unit. On the back
cover, move the Setup / Calibration Switch to opposite position. When power is re-applied, "F 1" shows on the
display. Allow a 20 minute warm-up period for the load cell(s) and indicator to become thermally stable.
2. While in the Setup mode, scroll to "F 16", then scroll down once using theZEROkey 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.
3. After making sure that there are no test weights on the platform, press ZERO to zero the value, then press the
NET/GROSSkey to save the zero point value.
4. 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.

Calibration / Continued
To calibrate the span using the F17 span calibration procedure:
1. While in the Setup mode, scroll to "F 17", then scroll down once using theZEROkey 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 four directional keys (shown at right) to adjust the
displayed value to the actual test weight value. Increase the
flashing digit by pressing the lb/kg key. Decrease the
flashing digit by pressing the ZERO key. The position of
the flashing digit may be changed by pressing the PRINT
key or theTAREkey.

4. After setting the exact value, press theNET/GROSSkey 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 next page).
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 adjust 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 theSpan Gain (F2).
