Load Cell / PR 6246 Series
Application:
The load cells may be used in multiple cell applications Class III and IIIL consistent with the model designations,
number of scale divisions, and parameters specified in this certificate. Load cells of a given accuracy class may be used in
applications with lower accuracy class requirements provided the number of scale divisions, the v
min
value, and temperature range are
suitable for the application. The manufacturer may market the load cell with fewer divisions (n
max
) and with greater v
min
values than
those listed on the certificate. However, the load cells will come with the appropriate n
max
and v
min
for which the load cell may be
used.

Identification:
An adhesive identification badge located on the cell, states manufacturer name, model, serial number, accuracy class
and rated capacity. Other pertinent information will be specified on the Calibration Certificate accompanying the cell.
Test Conditions:
A 100 kg, 200 kg and a 1000 kg capacity load cell were tested by the NMi Certain B.V., at the Netherlands facility.
Testing was conducted in accordance with the OIML DoMC Mutual Acceptance Arrangement, signed by the NCWM as a utilizing
participant for load cell testing. Testing was conducted using deadweights as the reference standard. The load cells were tested over a
temperature range of -10
o
C to 55
o
C with tests run on each cell at each temperature. The temperature effect on zero was measured and
a time dependence (creep) test was performed. The barometric pressure test to determine sensitivity of the load cell design to changes
in barometric pressure was conducted. The data were analyzed for multiple load cell applications. OIML R60 selection criteria were
used to determine cells tested.
