Communications Cables
Interface cables for connecting your AFG to peripheral devices:
Adaptor/Charger Unit
The mains adaptor/charger supplied with the AFG is a constant-current type.
Primary:
230V - 50Hz (110V - 60Hz version also available)
Secondary:
100mA constant current at 9V
Charger output plug:
Centre = positive Outer = negative
External ‘Smart’ Sensors - Calibration Principle
Mecmesin use standard mV/V sensors in all instruments. These sensors are subjected
to an excitation voltage from the host display (either AFTI or AFG) and the signal is
amplified. Due to the ratiometric principle, when the amplified signal is converted from
analogue to digital, the excitation voltage (also known as reference voltage) appears
on both sides of the conversion equation and therefore cancels itself out. In real terms,
the absolute value of the excitation voltage is unimportant to the conversion! Any
components that are not subject to the ratiometric principle have been specified within
the product design to be high-precision and their allowable deviation falls well within
the accuracy tolerance of the instrument. As a consequence of using this technique, it is
not necessary to match-calibrate the ‘Smart’ sensor to a specific display. You may only
return the ‘Smart’ sensor to Mecmesin or an authorised distributor for calibration.
