INTRODUCTION TO THE FI-80 SERIES DIGITAL INDICATORS

The FI-80 Series Digital Indicator is a general purpose, industrial grade force indicator. Two models are
available with different display types and power supply.

MODEL

DISPLAY TYPE

POWER SOURCE

FI-80 LED

Light Emitting Diode (LED)

110/220 VAC, 50/60 Hz

FI-80 LCD

Liquid Crystal Display (LCD)

Internal 6V battery with 12 VDC 800 ma charger


The LCD model contains a 6V rechargeable battery as the primary power source. The external power
supply with these units functions as a charger for the rechargeable battery and may also be used as the
main power supply.

The FI-80 is commonly outfitted at the factory with a load cell, hardware accessories and serial cable to fit
your specific requirements. It is calibrated and is ready for installation into your application. Alternatively,
your reselling distributor may have equipped this indicator for use with a particular load cell and calibrated
the system together. Confirm that a certificate of calibration is on hand for the FI-80 Indicator and load
cell combination. Prior to installation, you should view and record the calibration values in your FI-80.
This is found at the end of the SETUP section.

Please read this manual carefully and completely prior to using the indicator. Store the manual in a safe
and convenient place so it will be available if you have questions concerning the operation of your
system.

INSTALLATION

INSTALLING THE LOAD CELL

Install the load cell according to your specific equipment and application. Set-up will vary
between systems. Some things to keep in mind for best measurement performance
1. Insert the load cell fully in-line with the tensile or compressive force axis. Off center

loading may result in measurement errors.

2. Allow for movement and relief of undesired loads.

a. Compression load cells typically have one load cell end fixed in all directions

and the other end uses a load button or ball bearing to apply a single point load
that is free of undesired bending and torque loads.

b. Tension load cells are often not rigidly affixed to surfaces. In this arrangement it

becomes self aligning under load. Two convex surfaces contacting each other
offers good immunity from undesired bending loads and a limited range of
torque loads. An example is a lifting eye suspended from a shackle bolt.



CONNECTING THE POWER SUPPLY

The FI-80 LED indicator includes a hardwired AC line cord. Simply plug the unit into a
standard wall outlet.

The FI-80 LCD indicators ship with the rechargeable battery pre-installed. The external
power supply (included) can also be used to power the indicator. The adapter acts as the
battery charger and the FI-80 LCD must use a 12 VDC, 800 mA adapter.

1. Simply plug the AC adapter into the indicator’s DC Power Jack first, and then plug into a

standard wall outlet. Make sure that the AC voltage appearing at the wall outlet
