Storage and transport conditions:
– 20˚C to + 60˚C, 10% to 95% RH
Operating conditions:
+ 10˚C to + 40˚C, 30% to 85% RH
EW3004 was proven clinically by sequential comparison with auculatatory
measurement. The waiting period before EW3004 evaluation requires 1.5-2
minutes, and before auscultatory measurement of 0.5-1 minute.
