(keep two digitals after decimal.); Readout vernier value corresponding to nadir in measuring neck as foam and bubble disappear completely. Calculate out standard cubage VB (keep two digitals after decimal.) under 20 fuel dispenser �? Then measure oil temperature tB in the middle of the standard measurer; Empty measurer according to stipulation; Repeat Procedure 4 to 8 at least twice; Regulat flow rate to the minimum rate Qmin, as for appraisal or period appraisal after ground installation, Qmin = fuel dispenser 0.2 Qmax. Repeat Procedure 4 to 8 at least three times; Till now ground appraisal has been finished, namely, take six groups of data at least under two kinds of flow rate and repeat it 3 times. Data processing calculating formula Calculating formula for real volume VBt in standard measurer under testing temperature tj: VBt = VB [1+βY (tj - tB) + βB (tB-20) ] (6-1) Relative volume error formula: EV = (VJ –VBt) / VBt ×100% (6-2) Measure repeatability formula: En = EVmax �?Evmin (6-3) Flow rate calculating formula: Qv = 60Vj / t (6-4) Due money formula: PC = Vj · Pu (6-5) Due money error formula: EP = Pj －Pc (6-6) In above six formulae: VBt──real volume valve (L) under in measurer; VB──standard cubage of measurer under 20; βY , βB──volume expansion coefficient of appraisal media oil and measurer, respectively, (gasoline: 12×10-4/�? kerosene: 9×10-4/�? light diesel oil :9×10-4/�? stainless steel:50×10-6/�? carbonized steel:33×10-6/�? brass , bronze: 53×10-6/�? tj , tB──oil temperatures in flow meter (or nozzle outlet)and standard measurer VJ── cubage value (L) under tj�?temperature EV── relative cubage error (%) n ── measuring times fuel dispenser

leak test on the respective FP with the　　 defined logical nozzles (see Leak_Log_Noz_Mask　　 Data_Id 8).　　 The command is only accepted if all nozzles are returned.　　 If the command is issued to a dispenser in the wrong　　 device state or when a nozzle has been remov fuel dispenser ed it will　　 reject the command with a Data_ACK 3 (Command　　 refused in that state).　　 Please note that an Unsolicited FP_Status_Message　　 (Data_Id 100) must be transmitted as a result of this　　 command . This fuel dispenser action must occur even if the state has　　 not changed as a result of the command.　　 PCD Comment:　　 When the proprietary pump protocol does not support the　　 leak test. The PCD should reject this command with a　　 MS_ACK=5 and Data_ACK=5.　　 UNSOLICITED DATA　　 100 Bin8 M　　 FP_Status_Message　　 (64H) bin8　　 A FP_Status_Message must be sent unsolicited (without　　 bin16　　 acknowledge) by the FP whenever a change has occurred　　 in the status of the FP_State Log_Noz_State or the　　 Assign_Contr_Id or whenever the state cannot be　　 changed following request by the CD to change state.　　 The FP_Status_Message includes:　　 - FP_State (Data_Id = 20)　　 - Log_Noz_State (Data_Id = 21)　　 - Assign_Contr_Id (Data_Id = 22)　　 Please note that the FP_Status_Message Data_Id is built　　 up as follows:　　 100 0 20 01 fps 21 01 ns 22 02 acd　　 Where:　　 fps is the Fuelling Point Sate　� fuel dispenser
