  • Page 4: Initial Inspection

    SPLASH RESISTANT The 6010 meter is housed in a water-tighten case but should not be used underwater as the pH probe is not waterproof. The water resistant feature is to prevent permanent damage to the instrument when accidentally drop into non-corrosive solutions.

    3. If unsatisfactory results are gained after doing the above, notify your JENCO representative for possible repair or replacement (See WARRANTY). INSTALLING THE BATTERIES Replace the battery when the BAT indicator appears on the LCD. The instrument can operate within specifications for approximately one hour after LO BAT appears.

The [MEA./EFF.] key is used to bring the instrument out of the AUTOLOCK condition when operating in pH-AUTOLOCK or mV-AUTOLOCK mode. b.Press and hold this key for 5 seconds, the large LCD will display the efficiency of the electrode.

  • Page 9: Ph Calibration

    There are two sets of buffer available for this unit : 7.00,4.01,10.01pH and 6.86,4.00,9.18pH. You can change the buffer set by turning OFF the unit then pressing and holding the [STAND] key as you turn ON the unit again. You can see what buffer set you are using if the unit is uncalibrated and you are in pH mode.
  • Page 10 (refer to table 1). When a stable reading is reached, the WAIT annunciator will stop flashing and stay off. The SLOPE annunciator will start to flash. This means that the standardization at buffer 7.00 (or 6.86) has been completed and the instrument is now ready to sloped at a second buffer.

    After two point calibration, pressing and holding the [MEA./EFF.] key for about 5 seconds will display the new electrode efficiency. If "Er 2" is displayed, check that the correct buffer is used and that the slope of the electrode is not off by more than 30% from the theoretical slope.
  • Page 12 the WAIT annunciator will flash. This means that the instrument is waiting for a stable reading. The display will be locked to the buffer value corresponding to the temperature of buffer 7.00 (or 6.86) as set in 2.2 (refer to table 1).

After two point calibration, pressing and holding the [MEA./EFF.] key for about 5 seconds will display the new electrode efficiency. If "Er 2" is displayed, check that the correct buffer is used and that the slope of the electrode is not off by more than 30% from the theoretical slope.
  • Page 14 is completed and the instrument is ready to be sloped at a second buffer. The instrument will display the buffer value corresponding to the temperature of the buffer 7.00 (or 6.86) as measured in 3.2 (refer to table 1). If the reading still drifts, repeat 3.3 until a stable reading is obtained.

    After two point calibration, pressing and holding the [MEA./EFF.] key for about 5 seconds will display the new electrode efficiency. If "Er 2" is displayed, check that the correct buffer is used and that the slope of the electrode is not off by more than 30% from the theoretical slope.

  • Page 18: Measurement With Atc/Temp Probe In The Ph Non-Autolock Mode

    Press the measure key. The WAIT annunciator will start flashing. This means the instrument is waiting for a stable reading. The pH will track the pH value as sensed by the pH electrode and the ATC/Temp probe. When the display changes less than 0.01 pH in about 10 seconds the autolock function will be activated.

    Allow sufficient time for the display to stabilize. The instrument will display the pH value of the sample at the displayed sample temperature. If "OvEr/Undr" is displayed, the pH value measured is out of the “16.00/-2.00 pH” range. 3. Measurement with manual temperature compensation in the pH-AUTOLOCK mode.
