Technical Specifications: Measuring range 0-200 psi, 0-1380 kPa, 0-13.8 bar and 0-14.06 kg/cm2 Measurement resolution: 0.01 bar ANSI B 40.1 Grade A. Accuracy 2-1-2% of span Operating temperature: -15C to 60C 360 rotating head with 90 degree angled end and approx. 30cm flexible rubber hose Measurement memory, reset valve Durable rubber frame Gauge dimensions without hose: 110mm X 76mm X 32mm Weight: 212g (255g whole set) User manual: • Press the " ON " button to start using the gauge. • Press the " UNIT " button to change the measurement unit between psi, bar, kPa or kg/cm2. • Make sure the meter displays "0" (zero) before use. • To get an accurate reading, put the gauge head against the valve to get a good seal between the valve and the head, after stabilizing the pressure, remove the indicator from the valve to read the measurement. • After taking a pressure measurement, reset the pressure gauge by pressing the integrated reset valve (it is not advisable to leave the pressure gauge pressurized for long periods of time). • To turn off the blood pressure monitor, press the "ON" button or leave the monitor on as it is equipped with an automatic shutdown timer. • We suggest you measure your tire pressure at least once or twice a month. Correct tire pressure increases safety (improves traction), longer tire life (reduces tire wear) and lower fuel consumption (saves money). Facilitates pressure measurement in hard-to-reach valves Vans and trucks, motorcycles and other vehicles equipped with a Schrader car valve Measurement memory Even off the valve, the meter continues to show the last measurement until the user decides to reset it via the reset valve.
