4, Lake day letter Instrument Co., precision digital pressure gauge of current key: When you need a current detection instruments, click this button, LCD display measured values. Press the key repeatedly to achieve conversion between pressure, current, and the current percentage.
6, Lake day letter Instrument Co., precision pushboy digital pressure gauge testing transmitter: instrumentation with 24VDC power output, the transmitter is detected, the instrument opens directly to the current file, the red lead into the "24V OUT MAX30 mA" hole the black lead into "mA IN MAX20 mA" and the transmitter "+, pushboy -" a very direct connection, you can detect the transmitter. If you do not have the instrument 24V output voltage can be directly inserted into the test leads "mA IN MAX20 mA" pushboy and "COM" to 24V voltage source in series and then connected directly pushboy to the transmitter, the transmitter can also be detected.
