6 maintenance 6.1 Indicator Indicator detected correctly premise: You must ensure that the float of flexible working properly. Care must be taken to check the fastening screw is loose, remove the base or total demolition indicator (try not to disassemble) the position can not be changed, or it may cause misalignment between the float caused by deviation indicator. - Page 32 HT5 series metal tube flowmeter detected and the corresponding instructions. Output current deviation detection step instructions: Confirm pointer correctly (if there is no standard site traffic detection method is the only one float falls below the pointer points to accurately indicate the RP). And then to push the float detected indicating correspondence between the outputs.
- Page 33 is low (eg less than 10.8VDC), or even stop the phenomenon of self-test you should first ensure power supply (or cable) Is there a problem, you can pass a single 24VDC power supply confirmation. Meter anti-jamming measures requirements: due to the higher degree of intelligence (eg Hart communication), the instrument corresponding anti-jamming measures require a corresponding increase.
