YES Does the selfdiagnostic indicate problem location?

Also take precautions such as placing a removed CPU assembly into a bag with an antistatic coating. Turn the screw to the right to increase the zero point or to the left to decrease the zero output; the zero adjusts in manua of 0. You must press the shift key before entering each letter.

The third figure from the last shows the last one figure of the year of production. If such modification is absolutely required, contact Yokogawa. Parameters C21 and C22 are changed at the same time. Kanual transmitter is equipped with a self-diagnostic function which will be useful in troubleshooting; see Section 8.
