2.Safety
2.1. Operating Environment
• Operating Temperature: –10 to 50°C
• Humidity: <90% non-condensing
• Operating Voltage: Shown on Rear Label
2.2. Electrical Safety
• For your protection all mains electrical hardware must be
rated to the environmental conditions of use.
• Pluggable equipment must be installed near an easily
accessible power socket outlet.
• To avoid the possibility of electric shock or damage to the
instrument, always switch off or isolate the instrument from
the power supply before maintenance is carried out.
2.3. Cleaning
• To maintain the instrument, never use harsh abrasive
cleaners or solvents. Wipe the instrument with a soft cloth
slightly dampened with warm soapy water.

3.2. Operation Keys
Key Description
POWER: The <POWER> key is used to turn the
instrument on and off.
• To initially turn the instrument ON: Press and
hold the <POWER> key until the display starts up.
• To turn the instrument OFF: Press and hold the
<POWER> key for three seconds. The instrument
will display OFF followed by the three-second
countdown.
Note: If the <POWER> key has been locked, the
instrument cannot be turned off from the front
keypad.
• Battery Operation: When using batteries the
backlight will automatically turn off to conserve
power after a short period of inactivity. A short
press of the <POWER> key will turn the backlight
on again.
• Automatic Operation: The <POWER> key has a
memory function associated with it. This means
that the state of the power setting is remembered
even if external power is interrupted. It is therefore
possible to turn the instrument on in the safe
knowledge that it will operate whenever external
power is available and will not need to be manually
turned on again if the power is interrupted.
ZERO: The <ZERO> key is used to perform a Zero
adjustment on the scale display when an empty scale
has drifted away from a true zero reading.
• On the R320, the Zero adjustment is stored when
power is removed and is re-used when next
powered up.
• Long Press: When the indicator is set to Industrial
mode a long press of the <ZERO> key will remove
any stored zero adjustment.

Rinstrum - R300 Series Digital Indicator Operator Manual Rev 1.5
Page 9
Key Description
TARE: The <TARE> key is used to temporarily set
the scale to zero (such as cancelling the weight of a
carton before performing a filling operation). The
display will show the Net weight and the Net
annunciator will be lit.
• The <TARE> key can operate in all modes
(ie. Industrial, OMIL and NTEP).
• The weight tared is deducted from the allowable
range of the scale, reducing the maximum weight
that can be displayed.
• On the R320, the Tare adjustment is stored when
power is removed and is re-used when next
powered up.
GROSS/NET: The <GROSS/NET> key toggles the
weight display between the Gross weight and the Net
weight (provided that a Tare has previously been
acquired using the <TARE> key).
R320
Only
PRINT: The <PRINT> key on the R320 will trigger an
output of the current weight reading if a printer or
computer has been attached to the instrument and
the manual print function has been selected.
• The PRINT prompt is displayed while waiting for
the printer to accept data.
• If the printer is offline the PRINT prompt will remain
for a maximum of 10 seconds before the operation
is cancelled.
• Each weight printed is automatically added to an
internal total weight.
• Long Press: A long press of the <PRINT> key will
print the total. The total weight is then cleared
automatically.

Key Description
R310
Only
TEST: The <TEST> key on the R310 is used to
initiate a display test.
• Once pressed the display is shown with all
segments clear, then all segments lit and then all
segments clear again before returning to normal
operation.
• On the R320 the equivalent function is available
only when TEST has been assigned to the user
defined <FUNCTION> key. Refer to Testing the
Display page 13.
R320
Only
FUNCTION: The <FUNCTION> key on the R320 is
programmable to suit customer requirements. A label
identifying the special function will be attached. Refer
to Special Functions page 13 for details of the
available functions.
• Long Press: A long press of the <FUNCTION>
key may be used for certain functions depending
on the primary function of the key.
3.3. Stability Considerations
Once a <ZERO>, <TARE> or <PRINT> key is pressed the unit
waits for a stable valid reading before performing the associated
operation. If the weight readings remain unstable or invalid due
to some diagnostic error for longer than 10 seconds, the
operation is cancelled and the STABLE ERROR message is
displayed.

4.Basic Weighing
4.1. Normal Weighing
• Ensure instrument is On and Zero annunciator is lit.
• Place your item on the weigh platform.
• Read the weight display.
4.2. Using Tare
• The indicator displays zero with Zero annunciator lit.
• Place the container on the weigh platform.
• Press the <TARE> key.
• The indicator will show the displayed zero weight and the
Net annunciator will be lit.
• Fill the container to the required weight.
• Press the <GROSS/NET> key to toggle
between the Net weight and the Gross (total)
weight.

5.Special Functions (R320 Only)
5.1. Testing the Display
• Press the <TEST> key to clear the display then
show all segments of the display then clear the
display again before returning to normal operation.
Note: This feature is also available on the R310. For more
information refer to TEST key page 10.
5.2. Counting
• Place the container on the weigh platform and
press <TARE> if required.
• Place the sample pieces to be counted on the weigh
platform.
• Press and hold the <COUNT> key for two
seconds. The default number of pieces in the
sample will be displayed.
• Use the <GROSS/NET> and
<PRINT> keys to alter the
number of pieces. and
• Press <COUNT>. The current sample will be
stored against the entered pieces. The letter p(for
pieces) displays when in counts display.
• Press the <COUNT> key to toggle between the weight
display and the counts display.
• If printing is enabled the sample quantity and weight will be
printed.

5.3. Units Switching (kg / lb)
• Press the <UNITS> key to switch the display
between kilograms and pounds.
• Printing and serial communications will use the units
displayed (either lb or kg).
5.4. Hold
• Press the <HOLD> key to hold the displayed weight
at its current weight.
• The Hold annunciator will be lit.
• Press the <HOLD> key again to release the weight
reading and return the display to normal weighing.
• All printouts that print the displayed weight will use the held
weight reading if it is currently being displayed.
5.5. Peak Hold
• Press the <PEAK> key to show the largest absolute
weight, either positive or negative (eg. -30 is larger
than 25). The R320 compares the current weight
reading with the stored peak and updates the peak
reading whenever a larger weight is detected.
• The Hold annunciator will be lit.
• Press the <PEAK> key to toggle between the
current weight and the peak weight.
• When displaying the peak weight the Hold
annunciator will be lit.
• When displaying the peak weight, press and hold
the <PEAK> key for two seconds to clear the peak
value and reset back to 0 (zero).
• All printouts that print the displayed weight will use the held
weight reading if it is currently being displayed

5.6. Live Weighing
• Press and hold the <LIVE WT> key to switch
between normal weighing and live weight mode.
The display will briefly show NORMAL or
LIVE.WT.
• Note: During normal weighing, this key operates
exactly like a manual <HOLD> key.
• When in Live-Weight mode and while the Net weight is
within the zero 'dead' band, the instrument shows the
current weight.
• Press the <TARE> or <ZERO> key to
clear any residual weight and return the
scale to the zero state. or
• Move the animal on to the weigh platform.
• Once the weight moves outside the zero 'dead' band the
instrument begins to calculate a long-term average that
compensates for any movement in the mass. The
instrument flashes the Hold annunciator and shows the
current average value.
• The Hold annunciator is steady when the final sample
weight is shown on the display.
• Press the <LIVE.WT> key to force the sample to
be recalculated.
• Once the animal is removed, the R320 automatically clears
the previous reading ready for the next animal.

5.7. Showing Totals
• The <PRINT> key is used not only to print the
current weight but also to add that weight to the
current total.
• When the <TOTAL> key is pressed, the indicator
displays COUNT followed by the number of items
in the total.
• After this the indicator displays TOTAL followed by the
current total weight.
• If the total weight is too large to display in six digits, the
weight is shown in two sections labelled with the upper six
digits displayed before the lower six digits.
• Press and hold the <PRINT> key to cause the
total accumulated weight to be printed and then
cleared.
