NOTE: When manually entering the temperature make sure that use of the temperature sensor is
disabled (Temperature command 3). All following measurements will be corrected with the entered
value.
The SMT-200 automatically corrects the display contrast setting according to temperature measured
and indicated in system temperature.
Temperature command 2 allows you to measure the temperature with the use of the supplied
reference geophone. The SMT-200 measures the coil resistance of the reference geophone.
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. See Smartec connections in appendix A for further details.
The cable which connects the SMT-200 with the Docking Station does not have a built-in Smartec
sensor. The 1 m cable supplied with a Smartec sensor and RJ-11 connector at the other end provides
the SMT-200 with an identical temperature measurement option when it is connected to the Docking
Station.
When Smartec temperature measurement is enabled, choosing Temperature command 4 will refresh
the displayed temperature. In normal use the SMT-200 will automatically measure and update the
temperature every minute. If a test is being run at that time the update is due then the temperature will
be updated at the end of the test.
