Interpreting Specifications Interpreting Specifications Transmille have taken great care over presenting the extended specifications in a manner that is easy to read while including high levels of details Transmille specify specifications as both Total Accuracy and Relative Specifciation, with varying calibration intervals, from 24 Hours to 2 Years By 'Total Accuracy', this means that all internal components of the calibrator have been compensated for. This includes stability, line voltage variations, temperature, humidity as well as the uncertainty of calibration as performed by Transmille Ltd....

1 year Total Accuracy Specifications at Tcal ±5°C Range Typical Output 50 Ohms 0.2 Ohms 0.2 Ohms 0.5 Ohms 0.7 Ohms Stability (Accuracy relative to calibration Standards) Range Notes Note 1 : Allowance must be made for output resistance when driving into a load. Note 2 : Limited by 50 Ohm output impedance. Note 3 : Internally adjustable from 2mA to 30mA - Factory set to 20mA as standard. For safety the trip is controlled by a fail-safe circuit independant of the processor which shuts the high voltage output off in the event of an overload. Note 4 : Typical RMS noise figures at 50% of full scale,...

Time (Minutes) Current (Amps) Measurement Conditions : Ambient Temperature 20'C, Mains Voltage 230V, Mains Frequency 50Hz Allow at least 7 minutes 'off' period between current output Shorter periods will reduce the output time availiable. A higher ohmic value load (for example, a 0.1R Shunt) allows greater output time as more heat is dissapated within the shunt / load. With lower loads more heat is dissapated within the instrument, reducing output time Into a 0.1R Load outputs of up to 20A are available for periods of greater than 30 minutes continously, considerations of self heating of the...
