Window inquiries continue until the lower limit is set to "OFF". Up to 9 possible windows. Always set both limits to ≠ OFF for a valid window. fix EP1 at pH OFF Interpolation of volumes at fixed times (input range depends on the measured quantity: pH: 0...±20.00, OFF U, Ipol: 0...
2.6. Parameters, key Titration sequence of DET and MET (Activate pulse) (Stirrer ON) (Start delay) (Request ident.) (Request smpl size) The start delay time is waited off. The sample identifications and the sample size are requested. (Start conditions) The start volume is dispensed (no meas.value acquisition) and the pause is waited off. Titration: Dispense increments Acquire meas.
2.6 Parameters, key Reagent feeding and EP evaluation of DET The reagent feeding of DET is similar to the controlling, a human being would apply in manually controlled titrations: Great volume increments are dosed far away from the EP, small increments in the region of the equivalence point. The size of the volume increments dosed by the Titrino is determined by the following parameters: meas.pt.density min.incr. The measuring point density is entered as a relative value from 0...9.
2.6. Parameters, key Reagent feeding and EP evaluation of MET In monotonic titrations, the volume increment is constant over the whole titration curve. V step Volume increment. A prerequisite for good accuracy is the correct size of the volume increments. A good value is given by V step = 1/20 VEP (VEP = volume of the EP).
2.6 Parameters, key EP recognition criteria for DET and MET The parameter "EP recognition" offers you a range of possibilities to ensure selection of the EP you are interested in: If the desired jump is very large, you can select the "greatest" jump (with DET the steepest jump will be evaluated). Thus you always obtain just one EP per titration (EP1). If you wish to determine the sum of different components (e.g. acid or base numbers), the "last" jump can be the correct one.
2.6. Parameters, key Fix EP's Fix EP's allow determination of the associated volume value for every inputted measured value on the titration curve. This function is useful for performing standard methods such as TAN/TBN determinations. For the evaluation of fix EP's, the pH calibration is advisable. The volume values of the fix EP's are available for the calculation as C5X: Fix EP1 ⇒ C51 : Fix EP9 ⇒ C59 Maximum 9 fix EP's are possible.

The display shows then drift OK 2.3 ul/min or SET pH conditioning The vessel is now conditioned. The titration can be started with .
2.6 Parameters, key Control parameters The control parameters can be set separately for each end point. Optimize your control parameters for routine analyses for samples with a rather low content. During the titration, reagent dosing occurs in 3 phases: U/mV EP 1. Initial dosing: Here the dosing rate increases constantly. The rate starts with "min.rate" and goes up to "max.rate". 2. Continuous dosing: Dosing is performed at the maximum rate "max.rate" until the control range (dynamics) is reached.
2.6. Parameters, key Relation between the stop criteria "time" and "drift" The stop criterion "time", t(delay), means that the end point must be exceeded for a certain period of time. In other words, after the last dosed increment, time t is allowed to elapse before the titration is stopped. The size of this last increment depends on the volume of the Exchange Unit used. With a 20 mL Exchange Unit, the smallest possible increment is 2 ul.
2.6 Parameters, key If you have entered the endpoint and the control range (dynamics), the default values for the other control parameters should suffice for the first titration. If you encounter difficulties in optimizing your titration, the following table will be of use. How to proceed if ... Problem Dosing at the end too long and with too small increments. "Never ends!" Possible causes and corrective measures • Increase "min.rate". Perform an experiment with a much higher min.rate.

2.6. Parameters, key Control parameters for KFT The control parameters can be set according to your samples. The default parameters are already set to get satisfactory results. Optimize the control parameters for specific samples only. During the titration, reagent dosing is carried out in 3 phases: U/mV 1.

4.2. Diagnosis 4.2 Diagnosis 4.2.1 General The GPD Titrino 751 is a very precise and reliable instrument. Thanks to its rugged construction it is virtually impossible for external mechanical or electrical influences to have an adverse effect on its functions. Although the occasional fault in the instrument can not be excluded completely, it is certainly much more likely that malfunctions are caused by wrong operation or handling or through improper connections and operation with non-Metrohm instruments.

The display of before reappears. • Knob 'dV/dt' to right stop.
4.2. Diagnosis 11 External dosing units D 1 or D 2 This test makes sense only when the 751 GPD Titrino is operated in connection with external dosing units (685 Dosimat or 700 Dosino). The spindle drive and the cock changeover drive of the internal dispensing unit can be checked with the aid of the function (see page 99). • Connect the external dosint units D 1 or D 2 respectively. • Insert exchange unit and put the burette tip into a collecting receptacle.
4.3. Initialise and test RAM 4.3 Initialise and test RAM On the odd occasion large disturbing signals (e.g. mains spikes, lightning, etc.) can have an adverse effect on the processor functions and hence lead to a system crash. After such a crash the RAM area must be initialised. Although the basic instrument data remain stored, the RAM initialisation should be performed only when necessary since the stored user data (configuration, parameters, calculation variables, etc.) are cleared as a result.
4.4. Releasing a locked spindle 4.4 Releasing a locked spindle with inserted Exchange Unit • The burette drive may very occasionally jam at the top or bottom end of the cylinder. If jamming occurs at the top or when the drive is out of function, the Exchange Unit can no longer removed. In this case, it is necessary to proceed as follows: 2 screws (M4 countersunk) 2 screws (M3 fillister head) knob edge of bench Fig.
5.1. Setting up and connecting the instruments 5 Preparations The mains cables supplied with the instrument are three-core and equipped with a plug with an earthing pin. If a different plug has to be fitted, the yellow/green lead must be connected to the protective earth. Each break in the earthing inside or outside the instrument can make it a hazard. When the instrument is opened or if parts of it are removed, certain components may be live if the instrument is connected to the mains.

Settings at the Titrino: Under key , >peripheral units, "Remote Box: on" Keyboard: Select the country-specific keyboard layout of your PC keyboard.
5.1. Setting up and connecting the instruments The numerical block (with NumLock) and the number keys on the PC keyboard simulate the functions of the numerical keys on the Titrino. For example, entering <7> in the basic state of the Titrino switches the statistics on. Keys which are used for setting an accent (e.g. ^, ´) are converted immediately. If you try to enter ê the Titrino will display ^e instead. The occupancy of the PC function keys is shown to the right as an overlay.
5.2 Connection of electrodes, preparing titration vessel 5.2 Connection of electrodes, preparing titration vessel Rear panel: Ref Ref Connection for separate reference electrode.

Ind I Connection of pH, redox, ISE electrodes. Combined or separate electrodes. Select measuring input 1 or 2 in the Titrino.
5.2. Connection of electrodes, preparing titration vessel Practical tips • Glass electrodes should be preconditioned in the solvent used for ca. 1 hour. • If the potential jump after the first dispensing step is too large, a small start volume may help. • As an "auxiliary electrode", the 6.1808.030 burette tip with earthing may be used in some cases.
5.2 Connection of electrodes, preparing titration vessel Setting up the titration vessel The titration vessel is set up as shown in Fig. 5-6. During a titration, it is important to ensure that the solution in contact with the electrode is thoroughly mixed. This is achieved by • efficient stirring. But it should not be too fast, otherwise the stirrer vortex will suck in air bubbles and CO2 or O2 can disturb the titration. • positioning the burette tip as centrally as possible, above the stirring bar.
