• No powerful electric or magnetic fields 4.1.4 Adjust the angle of the terminal The angle of the terminal has two positions. − To increase the angle of the terminal, fold out the two feet (1) at the underside of the terminal. 4.1.5 Connect and disconnect the terminal Connect the terminal § The titrator has shut down. 1 Plug the supplied terminal cable into the socket in the back of the terminal. 2 Plug the terminal cable into the TERMINAL socket on the rear panel of the titrator.
NOTICE Danger of damage to the AC adapter due to overheating! If the AC adapter is covered or in a container, it is not sufficiently cooled and overheats. 1 Do not cover the AC adapter. 2 Do not put the AC adapter in a container. The titrator is operated using an AC adapter. The AC adapter is suitable for all supply line voltages ranging from 100...240 V AC ±10 % and 50-60 Hz. 1 Install the cables in such a way that they cannot be damaged or interfere with operation.
4.1.8 Set up the titrator for a general titration The illustration shows the setup of an Excellence Titrator for a general titration. For this setup you need a titrator, and the accessories "Manual titration kit" and "Interchangeable burette set.
4.1.8.1 Attach the titration stand to the titrator § The spacing ring, clamping ring and threaded ring are mounted on the titration stand. 1 Remove the cover from one of the mounting holes. 2 Position the titration stand over the uncovered mounting hole. 3 Place the screw in the hole of the titration stand and screw it in the mounting hole. 4 Tighten the screw. 4.1.8.2 Swivel the titration stand The titration stand can be swivelled among three predefined positions.
4.1.8.3 Attaching and removing the titration vessel Attaching the titration vessel § The titration stand is swivelled out. 1 Turn the threaded ring a quarter to a half turn clockwise. 2 Guide the titration vessel upward (1) into the titration stand and hold the titration vessel in place. 3 Tighten the threaded ring (2). 4 Check that the titration vessel is firmly attached before you let it go. Removing the titration vessel § The titration stand is swivelled out. 1 Hold the titration vessel with one hand.
2 Plug the compact stirrer into one of the STIRRER PUMP sockets on the rear of the titrator. 3 Start up the titrator. ð The titrator detects the connected compact stirrer. 4.1.8.6 Connect the measuring electrode § No task is running on the titrator 1 Insert the measuring electrode into an opening in the titration stand. 2 Connect the triaxial cable to the SENSOR1 socket or SENSOR2 socket of the analog board on the rear of the titrator. ð The titrator detects the measuring electrode. 4.1.8.
§ The burette is assembled. § The burette holder is mounted on the titrant bottle. § The piston rod (5) is in the home position. 1 Turn the arrestment knob (6) in the opposite direction of the arrow. 2 Orient the burette so that the recesses on the driver arm (3) are parallel to the groove (7) on the base of the burette housing. 3 Slide the burette (8) on to the titrator either from the left (as illustrated) or from the right (4).
Shut down the titrator from the touch screen − Tap Home > Log out > Shut down. ð The titrator stops running tasks and shuts down. ð The AC adapter and the control circuit for the power button are energized. The rest of the titrator is no longer energized. Shut down the instrument using the power button − Press the power button for less than 1 s. ð The titrator stops running tasks and shuts down. ð The AC adapter and the control circuit for the power button are energized.
5.2.2 Rinsing and filling the burette To fill the burette and tubes with titrant and remove any air bubbles from the system, rinse the burette three times with titrant with the manual operation Rinse. § The titrator is prepared as described in [Preparation } Page 23]. 1 To ensure that the system has no leaks, check all tubes and closing points for firm seating. 2 Make sure that the free end of the dispensing tube for the titrant is placed in the titration vessel or another container.
10 Remove the titration vessel from the titration arm. 11 Rinse the electrode with deionized water. 12 Repeat the last 3 steps for the buffer solution with pH 7.00 and the buffer solution with pH 9.21. ð When the calibration is completed, the calibration data is automatically copied to the setup. 5.2.3.2 Test the pH-sensor 1 Tap Methods > New > Standard method templates > Sensor test. ð A list of method functions appears. 2 Tap Sample (Calib). ð The dialog Sample (Calibration) opens.
12 Tap Start. ð The titer determination begins. ð The titrator asks you to add sample 1/1. 13 Attach the titration vessel with potassium hydrogen phthalate solution to the titration head and tap OK. ð The titration starts after the stirring time. ð During the titer determination, the online screen displays the measured pH values over the titrated volume in [mL]. ð After the titer determination is completed, the titer is copied to the setup.
2 Select the shortcut on the home screen. ð The dialog Start analysis opens. 3 In the parameter Enter sample size enter the sample size. 4 Tap Start. ð You are prompted to add the sample. 5 If the titration vessel is not attached to the titration arm, attach the titration vessel containing the HCl solution to the titration arm and tap OK. ð The titration starts after the pre-stirring period. ð During the titration, the screen displays the measured pH values over the titrated volume in [mL].
2 Tap Save series data (1) to save the current sample series. Only the completed samples will be saved. ð If the maximum permitted number of series has been reached, the series is not saved. ð Sample data from a method that is waiting in a queue can be saved by selecting Suspend > Save series data. 3 Tap Skip sample (2) to skip the current sample and continue with the next sample of the series. ð The current sample is marked in Results as Excl..
Titration stand 1 Loosen the threaded ring (4) and remove it from the titration stand (1). 2 Remove the clamping ring (3) and the spacing ring (2) from the titration stand (1). 3 Clean the parts of the titration stand. 4 Place the clamping ring (3) and the spacing ring (2) in the threaded ring (4). 5 Screw the threaded ring (4) into the titration stand. 1 2 3 4 7.
