Mounting
Mount case assembly on a pipe (nominal JIS 50A) as follows:
(1) Prepare a vertical pipe of sufficient strength (nominal JIS 50A: O.D. 60.5 mm) for mounting
the case assembly. (The sum of the case assembly and the calibration gas cylinder weighs
approximately 4.2 kg.)
(2) Mount the case assembly on the pipe by tightening the nuts with the U-bolt so that the metal
fitting is firmly attached to the pipe.
