Page 67025 Instruction Manual (Rev. 2)4.2 RateThe speed control potentiometer adjusts the geared motor to the desired speed, which isindicated on the 3-digit LED display labelled STROKE P.M. (see Figure 3 “Front Panel”).The speed is unaffected by either mains voltage variations or changes of torque loadbrought about by different stroke volumes, different cylinder/piston combinations, airwayalterations, status of the lubrication, etc.The digital display assures excellent reproducibility: you adjust the actual speed of thegeared motor against a displayed number, in lieu of trying to overlap a pointer and ascale mark.The digital reading involves the incertitude of the last figure. E.g., 150 STROKES P.M.could be any value between 150 and 150.9.4.3 Stroke VolumeThe stroke volume is adjustable via the STROKE VOLUME knob (14,see Figure 1 “Linkage”) located on the front panel (see Figure 3 “FrontPanel”) while the pump is either running or at standstill.Volume is clearly indicated by a pointer on a stationary dial (15): seepicture and Figure 4 “Stroke Volume Scale”.The scale indicates the volume obtained with 10ml cylinder/piston as-sembly.Please refer to Table 1 ”Stroke Volume Indication” table to find the vol-umes obtained when different pistons are used.See also paragraph 4.4.Figure 4 “Stroke Volume Scale”4.3.1 Volume Scale ReadingVOLUME SCALEREADING1 ml Piston(reading / 10) ml5 ml Piston(reading / 2) ml10 ml Pistonactual reading ml30 ml Piston(reading x 3) ml1 0.1 0.5 1 32 0.2 1 2 63 0.3 1.5 3 94 0.4 2 4 125 0.5 2.5 5 156 0.6 3 6 187 0.7 3.5 7 218 0.8 4 8 249 0.9 4.5 9 2710 1 5 10 30Table 1 ”Stroke Volume Indication” |
