Set-up Rotating switch With the rotating switch you choose the appropriate mode. OPERATE indication of measured value ZERO adjustment of min. value (4 mA) END adjustment of max. value (20 mA) POINT shifting of decimal point Plus/Minus key With these two keys you modify the value of the digital indication. When you keep the key pushed, the digital indication changes the value in three speeds. After each 28 steps, the counting speed increases by one step.
Set-up 3.3 Adjustment • The indication required the adjustment of the values for 4 mA and 20 mA. Proceed as follows: Set the rotating switch to position „POINT“ and push one of the keys. The digital indication starts flashing. By pushing the keys again you move the decimal point. The minus key moves the decimal point to the left, the plus key to the right. • Set the rotating switch to position „ZERO“ and push the plus key to increase the indication value or the minus key to reduce the indication value.
