OHAUS Quick Tips-Scout Pro Calibration
You want your students to obtain accurate and meaningful results
from their lab activities, calibrating your Scout® Pro balance
before each class is quick, easy, and ensures accurate
measurements.
Calibration is one of the most critical tasks to perform prior
to weighing with your OHAUS Scout® Pro electronic balance. Because
your students will be using the balance during multiple class
periods and several times throughout the day, a simple calibration
procedure completed prior to each class period will ensure your
students achieve the most accurate and meaningful results.
Better yet, consider incorporating a balance calibration activity
into your lesson plans for your students at the beginning of the
year. This will not only help them understand the importance
of calibrating their Scout® Pro balance, but will save you some
valuable preparation time before each class.
The traditional method of calibrating electronic balances is
with an external calibration mass. Users will typically calibrate
with a "span calibration" method, beginning with no weight on the
pan to obtain the zero point, and then placing a mass on the
balance to achieve a span point. Calibrating the Scout® Pro
electronic balance is a relatively quick and simple
procedure. Begin with your balance turned off. Press
and hold the ON/ZERO button until you see the word MENU on the
display. Release the ON/ZERO button and your display should
now read .C.A.L. At this point you will want to press the
ON/ZERO button one time (do not hold down) and the display should
briefly flash - C - and then flash the appropriate weight of the
calibration mass, included free with all Scout® Pro models up to
600g capacity.
For example, the Scout® Pro SPE401 will flash 200g indicating
that a 200g mass is needed to calibrate your balance. Once
you place the appropriate calibration mass on the pan, simply press
and release the ON/ZERO button. The display will then again
flash - C - and then donE. In approximately 30 seconds time,
you have properly calibrated your balance!
A couple of additional notes to keep in mind; although the balance
is calibrated prior to shipping, it is highly recommended you
calibrate your Scout® Pro when you first remove it from its
packaging to ensure it is working properly. The effects of
transportation and changes in temperature can have an impact on the
balances which are easily corrected through this process.
Also, if after you calibrate your balance you receive an error
which reads ERR1 or ERR4, consult the user manual for instructions
on linearity calibration.
5 Easy Steps To Calibrating
Your Ohaus Scout® Pro Balance |
Begin with the balance turned off
- Step 1: Press & hold the ON/ZERO button until you see MENU
on the display
- Step 2: Release the ON/ZERO button. Display should now read
.C.A.L.
- Step 3: Press the ON/ZERO button one time (do not hold).
Display should briefly flash -C- and then flash the weight of the
calibration mass needed
- Step 4: Place appropriate calibration mass on pan and press
ON/ZERO button. Display will again flash -C- and then DONE
- Step 5: Remove mass from pan and your balance is now
calibrated!
(Note: If display reads ERR1 or ERR4 follow manual instructions
for linearity calibration) |
When Should You Calibrate Your Scout® Pro
Balance?
- When you first remove the balance from the box to verify there
are no manufacturing defects
- Prior to each class period in which the balance is being
used
- You may want to incorporate a balance calibration lesson for
your students or make copies of these instructions for each
workstation in order to expedite the calibration process before
each class or lab
