Technical data EW 3004
Warning function Flashing figures on the display signal
Method of measurement: Intelligent measuring technology
(oscillometric) (FUZZY LOGIC)
Measuring range: Pressure: 0–280 mmHg
The device is vented automatically at
pressures exceeding 280 mmHg and
an error message is shown.
Pulse: 30–160 beats per minute
Measuring accuracy: Pressure: ±3 mmHg
Pulse rate: ±5 %
Leakage of pneumatic system: ≤ 6 mmHg/min
Inflation/deflation system: Automatic measurement during
inflation, and rapid deflation
Wrist circumference: 12.5–22.0 cm (4 7/8–8 5/8 inches)
Batteries: 2#1.5V alkaline (LR03/AAA/Micro)
(Control sign for battery change) Battery symbol appears when the
batteries have to be replaced.
Automatic switch-off: Approx. 5 minutes after measurement
Reference method for clinical trials: Auscultatory measurement
Weight: 95 g (without batteries)
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.
