7. Actual measurement 7.1 Cautions on measurement • When sample temperature and ambient temperature differ significantly, the upper left corner on display blinks. Here it blinks When difference in temperature between sample in the cell and ambient comes within approximately ± 5 ° C, it stops blinking. If the measurement data is going to be saved manually, not automatically, you have to wait until the data is stabilized after blinking stops.
(e.g. Sulfuric acid). If the syringe should be forced to be moved in this solidification state, it would scratch the inner surface, causing a possible leakage of a sample inside DA-130N. 7.2.1.2 Start measurement Only when is displayed (Stability:Auto), start measurement with [ok/meas.] key.
7.2.2 The use of commercially available plastic syringe 7.2.2.1 Sampling 1. Lower the sample discharging lever to the bottom. 2. Push the intake lever stopper upward to lock it. 3. Remove the screw stopper with a coin. Do not lose the screw stopper.
8. Calibration of measuring cell 8.1 Calibration with pure water (1) Set STD Calib. Mode at “Off” on Function <Calib.Mode>. (2) Press [esc] key 2 times to return to Main screen. (3) Sample pure water Note: Make sure that there is no air bubble in the measuring cell. (4) The measuring cell with pure water can be calibrated automatically with the key entry as follows: Press [cal.] key for more than 2 seconds to show inversed CALIB(Water) on display, showing calibration with pure water is in progress.
8.2.1 Calibration with standard liquid of which density is known The measurement precision of DA-130N as specified can be usually maintained with pure water, however, if more precision is preferred, calibrate with standard liquid of which density is known within the range.
: Air discharge rate 1 to 2L/min (a pump for tropical fish can be used) Desiccant tube : silica gel 5 to 10g in tube Connect the above to DA-130N as illustrated below: For 4mm tubes of inside diameter Desiccant tube Empty container Air pump (1) Thoroughly clean the measuring cell with pure water.
When the optional manual pump is used to dry the cell. (1) Before connecting the kit, clean the cell with pure water and ethylalcohol. (2) Press the sample discharging lever all the way down, and push the sample intake lever upward to lock (3) With the adapter for the syringe attached, connect the kit as illustrated below, and feed air forcefully and manually.
Note! Be sure to set the ‘STD Calib. Mode’ to “Off” in the Function menu (Calib. Mode) before performing calibration with air. 8.4 Calibration of displayed temperature Ordinarily, there is no need for calibration since the instrument has been calibrated in plant before shipment.
