4.7 Manual Temperature Compensation:
4.7.1. DO NOT connect the temperature probe to meter.
4.7.2. Press and hold the MODE key for 3 seconds to enter temperature setting mode.
4.7.3. Press ▲ or ▼ key to set the temperature of the sample.
4.7.4. Press ENTER key to confirm, the meter returns to measurement mode. Setting is
completed.
In the temperature setting mode, pressing and releasing the ▲ or ▼ key will increase or
decrease the temperature value by 0.1. Pressing and holding the ▲ or ▼ key will increase
or decrease the temperature value by 1.
5.1 pH Calibration
The HC1000 allows up to a 5 point calibration in the pH mode. We recommend performing at
least a 2 point calibration for more accurate measurement. The meter will automatically
recognise and calibrate to following standard buffer values.
USA Standard Buffer
Options pH 1.68, 4.01, 7.00, 10.01, 12.45
NIST Standard Buffer
Options pH 1.68, 4.01, 6.86, 9.18, 12.45
DIN Standard Buffer
Options pH 1.09, 4.65, 6.79, 9.23, 12.75
If you selected the user-defined option in the setup menu, the meter will allow only 2 point
calibration.
Single point calibration should only be carried out with buffers of pH 7.00, 6.86 or 6.79,
otherwise calibration will not be accepted.
Ensure that the meter is calibrated when attaching a new electrode or before first use. DO
NOT use visibly dirty calibration solution; contaminants in solution will affect the calibration
and eventually the accuracy of the measurement.
5.2 Single Point Calibration:
5.2.1 Ensure that 1 point calibration is selected in the setup menu.
5.2.2 Rinse the pH electrode with distilled water.
5.2.3 Ensure the display shows the pH indicator, and press CAL key, the meter shows
“pH7.00/CAL” (or “6.86/CAL”, “6.79/CAL”).
5.2.4 Immerse the pH electrode in the pH7.00 (or 6.86, or 6.79) buffer solution. The tip of
the electrode must be completely submerged in the calibration solution. Stir the
solution gently to ensure homogeneity.
