Azbil Corporation No. SS2-SLX100-0100 - 9 - Note *1) Make sure that this is done after completing installation at the site. *2) Match the liquid level measurement output with what is being indicated in the glass gauge. Zero can be adjusted to be set to a point anywhere between 0- 100% of the range to match. Display on communicator screen 1. Input liquid level 2. PV value 3. Torque tube temperature 4. Instrument temperature Calibration Proofing by the communicator using a weight is possible. Others Self-diagnostic functions External adjustment Use screwdriver (flat screwdriver) from external side of instrument. Zero, span and damping adjustments are possible. Built-in indicator must be selected to use this adjustment. Note) Change of specific gravity range . It is necessary to define the specific gravity of the liquid to be measured in order to manufacture the model SLX correctly. However, range change with the communicator will suffice for range setting change for the ranges listed below. . The scope of range change by the communicator depends on the float size for medium specific gravity range (model SLX110) / or low specific gravity range (model SLX120). Also, note that there is a limitation on boundary surface measurement (hydrometer) specifications for the low specific gravity meter (model SLX120). 1. Medium specific gravity (model SLX110): 1-1. For liquid level measurement specifications, range change is possible within the ‘Specific Gravity Range’ as given in Table 8 below. 1-2. For an boundary surface measurement (hydrometer), range change is possible within the scope given in Figure 2 "Range of Specific gravity". The parameters are as follows: . Boundary surface measurement: Δγ = γ3 - γ2, γ3 > γ2 Whereas: γ2: Specific gravity of upper layer liquid γ3: Specific gravity of lower layer liquid . Hydrometer: Δγ = γ5 -γ4, γ5 >γ4 Whereas: γ4: Upper limit of specific gravity measurement γ5: Lower limit of specific gravity measurement 2. Low specific gravity meter (model SLX120) 2-1. Range change of liquid level meter specification is allowable within the “Range of Specific gravity”, as given in Figure 2. 2-2. Boundary surface measurement (hydrometer) specifications have following limitations on range change: . Input Δγ from the the communicator. . The result of specific gravity range change may fall outside of SS specifications, thereby accuracy cannot be achieved. The accuracy of the meter after range change can be verified by substituting specific gravity γ, with the differential specific gravity Δγ in the verification equation on page 12.
