31 4-12. How to connect the optional printer or a personal computer (PC) The optional printer can be connected to the D155 unit so that the measurement and calibration results together with the date and time of measurement can be printed out. Connect the supplied printer cable to the RS-232C port (DB-9M) on the back of D155 unit as shown. A personal computer (PC) can be connected instead of the printer so that data can be exported.
32 5. Maintenance 5-1. Daily check 5-1-1. Cleaning the measuring cell When the repeatability of measurements has degraded or measuring time is prolonged, the measuring cell is considered to be contaminated. Also, when the cell is apparently contaminated with a sample of such nature, the measuring cell must be cleaned with an appropriate solvent like household chlorine bleach, acid or alkali.
33 5-2. Other maintenance 5-2-1. Replacement of the power fuse If the power fuse should blow, replace it with a like size and power rating. Note the fuse size and rating is listed on the rear of the instrument immediately above the fuse holder. As shown below, turn the fuse holder cover by 90 degrees counterclockwise using a flat screw driver. After the fuse is replaced, turn the fuse holder cover back 90 degrees clockwise. Warning! Be aware of the danger of electric shock.
34 4) Loosen the screw with the provided wrench 5) Tighten the tube nozzles clockwise – hand-tighten only 6) Follow steps 1 thru 4 in reverse to tighten the Injection Adapter nut and remove the red PTFE tubing CANNON® D155 Density Meter Instruction & Operation Manual Version 1.
35 5-2-3. Replacement of optional peristaltic pump tubing If the pump tube is deteriorated, the tubing may fail causing sample liquid to leak. This may eventually lead to pump failure. Replace pump tubing as follows: 1) Disconnect the tubes connected to the pump tube cassette. 2) Turn the cassette counterclockwise to remove it. 3) Remove the tube joint from the cassette by pulling one of the ends, and then pull out the tube.
36 5) Fit in the new pump tube around the rotor as shown by pulling it out a little bit. Fix the tube joint securely to the groove as illustrated. Pump tube Rotor Pull out 6) Match the axle and rotor, and fix the Tube joint Match Axle cassette by turning clockwise until it stops. Pump tube Fix the cassette by turning clockwise until it stops. Caution! Some samples may shorten the life of the pump tubing. pump tubing when appropriate.
