Pump-flow Integrator - operating instructions |
The PUMP-FLOW INTEGRATOR is an auxiliary piece of equipment for all LAMBDA instruments. The operating instructions for the integrator are identical for all instruments. 1. CONNECTION OF THE INTEGRATOR TO THE PUMP Insert the 5 pole plug of the integrator marked "input" into the corresponding socket (A) of the PRECIFLOW pump (figure 1). 2. CONNECTION TO A REGULATOR (pH-stat, pO2-stat, thermostat) Plug the 5 copper wire remote control cable (Cat. no. 4802 or 4810) into the socket "remote control" on the rear side of integrator and lock it by screwing the security ring into the socket. 3. CONNECTION TO A RECORDER Connect your recorder using sockets 0/+ "recorder" on the rear of the integrator. 4. ADJUSTMENT OF THE INTEGRATION SENSITIVITY The sensitivity of integration can be varied in the range of 1 to 512 by division of the step frequency of the motor. The sensitivity is adjusted by a decimal switch "sensitivity". If you increase the number by one, the frequency of the step is halved. The full scale of your recorder will indicate a two times larger volume of liquid. If you select a lower number the effect will be the opposite. 5. CALIBRATION OF THE TUBING The diameter of the tubing has a major effect on the flow of the liquid through the pump. The diameter of the tubing changes slightly during its production, therefore it is necessary to calibrate each lot of tubing . The easiest way is to measure the volume of liquid being pumped between the two automatic resets of the integrator. This gives you the volume of the full scale of your integrator for the specific tubing and sensitivity. 6. RESET You can reset your integrator anytime by pressing the red reset button. 7.
