Sine wave
DC/DC
Powers the SMT-200 analogue circuit up or down to
enable analogue circuit test measurement.
Attenuator
Sets attenuator range setting, value must be between 0
and 255. Enter value via keypad or using the arrow up/dn
keys.
Freq.
Sets sine wave frequency between 0.018 and 291.304
Hz. Enter value via keypad or using the arrow up/dn keys.
Press
ENTER/START
to accept value or right arrow key to
escape.
Tests
Analogue
measures and records: Internal temperature, Offset, DC
resistance, Distortion and Dynamic resistance.
Noise
Input terminal noise is continuously measured and
displayed. Exit test by pressing 0.
AC Gain
Each range (0.08, 0.16, 0.31, 0.63, 1.25, 2.50, 5.00,
10.00) is tested using a sine wave voltage and the
measured offset and AD reading is reported.
DC Gain
Each range (0.08, 0.16, 0.31, 0.63, 1.25, 2.50, 5.00,
10.00) is tested using a DC voltage and the measured
offset and AD reading is reported.
Leakage
Is continuously measured and the resultant value
displayed. Exit test by pressing 0.
2.23.3 Temp. menu
Read or set the external temperature and temperature options
It is important to compensate the SMT-200 results to allow for temperature variations. The materials
used within the string itself have a temperature coefficient, which means the geophone properties will
change with temperature. The operating menu allows you to make the compensation on the data or
specs. The temperature menu allows you to set the temperature used in the calculation.
