Page 19: Layout
Section 2 SMT-200 Operations SMT-200 Layout The SMT-200 consists of two parts, the main case and a removable battery pack. The battery pack must be connected for mobile operation. Operation is still possible when connected to the supplied docking station, in which case the battery does not need to be connected. If the battery pack is attached to the main body the docking station will be monitoring the battery and will be automatically charging the battery as required.

The materials used within the string itself have a temperature coefficient, which means the geophone properties will change with temperature.
Page 39 Assuming any deviation from the nominal value at 20°C is due to temperature variation the actual temperature can be calculated. There is a Smartec temperature sensor built into the Bendix connector of the SMT-200. It is important to make sure that the temperature of this connector is the same as the temperature of the geophones under test.

Page 53 NOTE: If the configuration or the geophone specification file (SMT200.CFG & SPC.TXT) on the PC are a later date than the same file in the SMT-200 they will be automatically updated from PC during the File Transfer sequence. This may overwrite and thus alter test specs. in the SMT-200. It is generally recommended to change test specs.
Page 54 • The SMT-200 to Docking Station cable is not connected properly. • Docking Station's power is off: the SMT-200 will be switched on however, but the communications circuit needs power. • PC is not ready, i.e. other processor tasks are taking too long, causing time-out errors.
Page 55 Technical Note: When downloading a file from PC to the SMT-200, the old version is put into the free memory first. If transfer fails then it is restored. When transfer fails within a minute the SMT-200 will reboot. This is the reason why it could be fatal to interrupt a failing transfer by just switching off the power and/or disconnecting the battery.

Page 86 The address decoder shown on sheet 7. of the SMT-200 Schematic. The SMT-200 hardware is mapped into the PC I/O locations by U1, U3 and U4. The output of U4 (pin 8) is low when there is an I/O read or write to a valid (1B0h to 1BFh) location. This is further decoded by U1 to generate the enable signals for the various devices.
Page 87 ENTER/START Digital to Analogue Converter The digital to analogue converter circuit is shown on sheet 7 of the SMT-200 Schematic. The digital to analogue converter (DAC) is formed around a lookup table stored in the EPROM, U12. This contains the digital values for a low distortion sine wave. The clock for each sample starts at the PC speaker.

Page 105 The fundamental principle the SMT-200 uses for its tests is the idea that conductors breaking magnetic flux lines producing a current can be applied in reverse. The SMT-200 can apply current to a phone under test which will physically move the coil. This movement will indirectly produce a voltage we can measure.
Page 106 TEST PRINCIPLE……… The SMT-200 monitors the output of the geophone for 800 samples over 96 ms, the average level of noise is then computed. The lower the noise valve the better. In practice (depending on the geophone string confoguration) a result of less than 30mV ambient noise ng picked up will not effect the results.
Page 107 The normal way of doing this is a process know as damping. SMT-200 Operations and Technical Manual 2.00/R1...
Page 108 Shunt resistors have an effect on the sensitivity of the geophone and so does the recording systems input stages. The seismic detector response curves shown in the Sensor geophone specification sheets show the open circuit (OC) damping sensitivity curve at the top and the damping curve with various values of shunt resistors underneath.
Page 109 In the case of the SMT-200 the test frequency is determined by the user but for each period during the recording interval, 32 samples are taken and averaged. The result is then converted to the frequency domain so a 32 point FFT can be applied to work out the fundamental, second and third harmonics.
