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.
Indicators measuring tube is one to one. Note that the indicator measuring tube machine
number the same, even the same Caliber and indicator parameters are not interchangeable。
Indicators detection step and troubleshooting. Remove the instrument as a whole, check
the float free from corrosion, damage, float flexible action, check float may fall below
the most.
Pointer examination and treatment methods.
Pointer adjustment method:
Instrumentation is positioned vertically below the float falls, check whether the
correct pointer indicates the RP point, if not indicate RP points can be transferred pointer
RP points. Move the pointer to position the upper and lower limit position, and then forced
up the shaft from the local pointer or screwing down (the same as an ordinary pressure gauge
pointer) until the pointer indicates the exact point RP. Or secured by some of the large
slotted screwdriver in the top of the pointer word groove, then turn the pointer reaches
the exact point RP.
Pointing operation is not flexible check processing methods:
Pointer bearing retaining ring loose severe, treatment methods, see below "Output current
detection step and Troubleshooting" relevant part. Prolonged use or harsh field environment
case, if the bearing is not flexible phenomenon occurs, it can point a little higher in
the bearing portion lubricant item number (such as watch oil).
Output current detection and troubleshooting steps:
The float falls below the detected output current is 4mA to push the float so that the pointer
indicates the intermediate points (note that not only struck the hand detection, otherwise
large deviation), check whether the pointer flexible operation, the output current is
