4.2.1 Protection against electrostatic discharges (ESD)
Equilibrate potentials by touching earthed metal objects, e.g. housing of some electrical equipment
connected to the supply, central heating radiator etc.
R
In order to avoid fresh electrostatic charges, do not move unnecessarily backwards and forwards on
your working area. Where available, it is best to wear an antistatic wristband for continuous discharge of
static electricity.
R
When you remove the TAM from its antistatic packaging, touch first the front panel of the module to
equilibrate the potentials.
R
For the internal adjustments place the module flat on the foil of the antistatic packaging.
R
Take care in handling the amplifier module, avoid bending the circuit board and unnecessary touching of
its components.
R
Before inserting the module in the housing, ensure potential equilibration between the module, yourself
and the housing. First touch the metal housing before inserting the TAM.
R
When handling the module during use it is equally important to ensure that no electrostatic discharges
take place through the inner pins of the input or output sockets. For this reason you should always first
provide potential equilibration between yourself, the PLUGSYS and the transducer or recording system.
4.2 Internal settings, jumpers
In order to adjust the TAM to the individual application the following settings have to be made with jumpers on
the module circuit board. See diagrams next page !
R
R
R
Jumper J1 (TAM-D only): position of decimal point on the digital display
Jumper J2: gain of the input amplifier GAIN x1 - x1000 (the overall gain is 10x higher due to the subse-
quent output amplifier)
Jumper J3: time constant for the MEAN output 0.1 or 0.3 Hz
R
Jumper J4: PULSE or MEAN output at the BNC socket on the front panel
R
Jumper J5: bus lines AV1 - 16 for the internal signal outputs PULSE and MEAN
R
Jumper J6: (TAM-D only) input filter of digital display SLOW - FAST
R
Jumper J7: input selection between transducer with resistance bridge circuit (POS.2) or voltage input
from transducer with integrated amplifier (POS.1)
R
Jumper J8: to adjust the calibration range of the autozero to the selected amplification and the internal
resistance of the transducer.
Modern electronic components are very sensitive to electrostatic discharges. Even the smallest electrostatic
charge may damage the electronics or lead to faults. Therefore follow the steps described below in order to
discharge any possible static electricity on your body.
