楼上讲的正确。
1. Connect Terminal 10 (Comp) and terminal 11 (Mana) with M.
10、11与M 短接。
2. The display of the analog values shows an underflow (Hex 8000) immediately even if the current measured is clearly above 1.1185 mA 。
显示－３２７６７：下溢（低于1.1185 mA ）；
3. If the current exceeds 22.81 mA, an overflow message stating Analog input measuring range / High limit exceeded is displayed.
The display of the analog value (HEX 7FFF) is in the overflow range.
显示３２７６８：上溢（高于22.81 mA）。
4. ４－２０mA正常取值范围：0-27648。
