For example, a 1.6 mpa. How do you measure it?!
Multimeter hit 2K (digital table), measuring remote table above three terminals in any two terminals: if it is 400 Ou mother, these two is high-end, low-end, and the rest that is the sliding end (middle end). Next, the access line, if the clock indicating pressure increases, while the display is declining, the high-end, low-end swap line.In general, three terminals, the bottom is the middle end, the middle is high-end, and the top is the low-end. Consistent with the electric contact pressure gauge.Have a try.In general, three terminals, the lower end of the remote meter to measure the above three terminals in any of the two terminals, the top is the low-endIn order to measure the current, the voltage of the standard resistance is measured, and the current is calculated according to the voltage. The output between 4 and 20mA depends on the type of the remote meter. Analog remote meter is generally 4 to 20mA output, to determine whether the pressure gauge is normal, if it is digital remote meter, that is, high-end 24V voltage, multimeter is not measuredA high, medium, and low end pressure gauge shall be a three position contact type control pressure meter. If no signs are available, you can use either the ohmmeter or the buzzer test of the meter. Use the pencil first low limit hands to contact with the actual pressure gauge contact is closed, with a multimeter measuring three end exchange both ends of the middle and low end, the rest is high, then closed contact separately, the high pressure closed with the actual pointer to pointer, and then test interoperability both ends of the middle and high, so you can points out.
