Teledyne MODEL T703 Manual Do Utilizador

TEST CHANNEL calibration needs to be carried out on first startup of the analyzer (performed in the factory as 
part of the configuration process) or whenever re-calibration is required.  The analog outputs can be calibrated 
automatically or adjusted manually. In its default mode, the instrument is configured for automatic calibration of 
all channels, which is useful for clearing any analog calibration warnings associated with channels that will not 
be used or connected to any input or recording device, e.g., datalogger. 

During automatic calibration, the analyzer tells the output circuitry to generate a zero mV signal and high-scale 
point signal (usually about 90% of chosen analog signal scale) then measures actual signal of the output.  Any 
error at zero or high-scale is corrected with a slope and offset. 

Manual calibration should be used for the 0.1V range or in cases where the outputs must be closely matched to 
the characteristics of the recording device. Manual calibration requires the AUTOCAL feature to be disabled. 

Automatic calibration can be performed via the AOUTS CALIBRATION command, or by using the CAL button 
located inside TEST_CHANNEL submenu.  By default, the analyzer is configured so that calibration of TEST 
CHANNEL can be initiated with the AOUTS CALIBRATION command.
