Technical Data for the Transmitter Head
Instr Instrument Instr ument accur accuracy: accur accuracy:
acy: ±0.5 mm ± (5/256 in.) [The instr ument accuracy is given as a 2σ value.
This means that approximately 97% of the measured values are within the 0.5 mm tolerance.]
Maxim Maximum Maxim um instr instr instrument instr ument deviation: deviation: ±0.8 mm (1/32 in.)
Ambient Ambient oper operating oper ating temper temper temperature:
