Description
The MP4 shown in figure 1-1, includes the Electronic Control Unit, the Beam Drive Module, Data Logging
software, the RS-232C interface and cable, a base plate, Optic Mounting Assembly, a device holder for flat
substrates, a set of calibration weights, spare fuses and this instruction manual. In addition, the user must
order a separate beam, available in 10 gram, 100 gram, or 1000 gram. Included with each beam is an
assortment of hooks, a hook insertion tool and spare lamps. Optional accessories include hooks, beams,
optics, device holders, and a serial printer.
The accuracy of the MP4 system is
r
2% of the reading or
r
2% of the beam scale, whichever is greater. For
example, the accuracy of the 10 gram beam is
r
0.2 grams, the 100 gram beam is
r
2 grams, and the 1000
gram beam is
r
20 grams. The conversion from grams-force to Newtons is accurate to within
r
2% using the
force of gravity as 981 gm

. The worst case error caused by the deflection of the beam is 0.4%
which is included in the system error specification. The error caused by operator misalignment of the hook
