the difference of temperature between test solution and the calibration solution, the higher the measuring accuracy is. Typically, temperature difference between test solution and calibration solution should ≤±15°C; for high accuracy measurement, the temperatures should be the same. 4.5.7 When the meter is functioning abnormally, please set P4 as “ON” to restore the meter to factory default mode, and then perform calibration and measurements again. -

(b) After the second-point calibration, (see item 5.2.3.), press to confirm two-point calibration and return to measuring mode. The indication icon L and M for two-point calibration will appear on the lower left corner of LCD. User can choose pH4.00 and pH7.00 to calibrate if the measurement is within the acidity range and choose pH7.00 and pH10.01 to calibrate if within the alkalinity range. - Page 10 (c) Press key to enter next parameter setting or press key to confirm and return to measuring mode. 5.4.3 Purified water pH temperature compensation setting (P2) (a) Short press key in the mode P1, the meter enters mode P2, see picture (4-3). to choose ON or OFF.

5.4.7 Auto power off time setting (P6) (a) Short press key in mode P5 to enter mode P6, see picture (4-7). (b) Press key to choose the time: 0min, 10min or 20min. The auto power off function will be closed if choosing 0min. - Page 12 5.5.4 Always keep the meter clean and dry; especially around the socket connecting the meter and electrode, otherwise it may lead to inaccurate measurements or a damaged probe/meter. To clean, dry them with medical cotton and rubbing alcohol if the connectors appear dirty. 5.5.5 The sensitive glass bulb at the front of the combination electrode should not come in contact with hard surfaces.
