The E500R is a microprocessor based digital meter that is
designed for use with all Osborne Accu-Arm
and is directly interchangeable with the 500 Mechanical
Dial, the E500 Electronic Meter and, the E500M Electronic
Meter.
The E500R can read, display and totalize weights in pounds
or kilograms. It has two programmable scale ratios, Scale
1, and Scale 2. Scale 1 is factory programmed to work with
the Osborne Accu-Arm
scale. Scale 2 is user program-
®
mable. The E500R also features a Direct Scale capable of
measuring direct weights to 50 pounds, (22.7 kg).
The E500R "Freezes" on the correct weight after an adjust-
able "sampling" interval for each animal. The E500R pro-
vides a totalize function which adds each animal's weight to
a summary total of all animals weighed. The E500R features
an auto-zeroing function that automatically recalibrates the
scale to zero as the tare weight changes as the result of
debris accumulating on the scale platform.
The E500R has a water and dust resistant case that pro-
vides reliable service in harsh environments. An RS232
port is available for connection to auxiliary devices like the
Osborne ID Logger or a PC for automatic weight acquisi-
tion. Contact Osborne Customer Service at 800-255-0316
about instructions for the RS232 port.
INSTALLING THE BATTERIES
The E500R is powered by two D-Cell alkaline batteries, (not
included). To install new batteries, loosen the six screws
in the back of the E500R case. Carefully open the back
cover. Caution: A ribbon cable connects the front of
the case to the rear. Open the case only enough to install
the batteries. Use only fresh, alkaline batteries. Place bat-
teries according to the diagram on the back of the circuit
board. Carefully close the back cover and tighten the six
screws. During operation, a flashing colon (:) will appear
in the display window to indicate low battery power. Very
low battery power will be indicated by "batt". Replace the
batteries immediately for continuous service. Replacing
the batteries will not clear the memory.
INSTALLING THE METER ON THE SCALE
To install the E500R on an Accu-Arm
tach the E500R between the upper and lower dial hanger
hooks.

KEY FUNCTIONS
Turns the scale on and off.
Used during programming to increment display.
Restarts display of weight measurements after the
display has "frozen" on a weight.
Zeros out the scale. This button must be
held for one second before zeroing occurs, (to pre-
vent accidental zeroing).
Adds the current reading to the total and increments
the total count. The total count will be displayed for
two seconds and then the total weight will be
displayed for two seconds. This button must be held
down for one second before the totalizing process
begins, (to prevent accidental totalizing).
Used during programming to decrement display.
SCALE 1: Used to select Scale 1.
Displays the current total count and total weight
when pressed. This button will not add to the total
weight, only display the count and weight. If this
button is still pressed when displaying is complete,
the total count and weight will be cleared to zero.
Used in programming to move digit space to left.
SCALE 2: Used to select Scale 2.
Pressing this button will convert the weight to the al-
ternate standard of that chosen during user setup. If
pounds were chosen, "Kilo" will display as the alter-
nate and will be displayed for one second before the
alternate weight is displayed. If you continue to press
the button, the converted weight will continue to be
displayed.
Used in programming to move digit space to right.
DIRECT: Used to select the Direct Weight Scale.
