The firing voltage should be very close to the setting of 25Volts.
FIRING VOLTAGE
The firing voltage determines the amount of energy put into the firing wire to make it glow and ignite the cotton fuse. There are no strict rules on how to setup the firing voltage. A setting of 25V is standard. If the wire blows off with every firing then the voltage is set too high. You should get approximately 50 firings out of one wire.
Learn MoreCOTTON & WIRE CORRECTION
The sample is ignited by sending a current through the firing wire. This makes the wire glow, which in turn ignites the cotton thread, which in turn ignites the sample. The cotton and wire correction compensates for the electrical firing wire energy and the energy of the burned cotton.
Learn MoreZERO THE PRESSURE TRANSDUCER
The pressure transducer which monitors the vessel pressure for Filling and oxygen leakage needs to be offset adjusted so that it reads ZERO at atmospheric pressure. Although a pressure offset of 0.2 bar makes no difference to the CV determination, it can cause concern during the safety precautions and the power up check.
