2.1.1
Autozero Function
When GSM is switched
ON
, the initial menu choice is between making measurements
and configuring the instrument to suit t
he user’s specific requirements. The detailed
menu options will be discussed later.
As each GSM transducer has a built-in identification chip, its electronics is able to inter-
rogate each transducer and adjust its own internal specification, to match that of the
transducer.
Prior to making any measurements, GSM automatically balances out any offsets using its
autozero
function. Thanks to this feature, GSM does not require calibration.
2.2
Base, Grasping Tools & Force Transducer
The grasping tool can
be chosen among the
three
provided
as
standard: a
T-shaped
bar
,
rat trapeze
and
mouse trapeze
), de-
pending on the animal
on test, and on per-
sonal preference.
All tools may be con-
nected to the same
transducer, positioned
on the 13mm diam
upright, fitted on the
PVC base plate.
The transducer height
is adjustable.
Figure 2 “Base, Grasping Tools and Transducer
When the pulling force is applied to the transducer, the display on the electronic unit au-
tomatically shows the current grip force expressed in grams and in gram decimals.
A sound alarm can be set to advise when the maximum desired force is reached.
The force transducer has a
resolution of 0.1g
and the
maximum applicable force is
1500g
. The force transducer incorporates a proprietary memory chip to store all calibra-
tion parameters, so that no further calibration is required for normal use, see also para-
graph 2.1.1.
