OPERATIONAL PROCEDURES
A. Buffer Set Selection
The 6010M meter has two buffer sets: 7.00, 4.01, 10.01pH and 6.86,
4.00, 9.18pH. The meter is factory pre-set at 7.00, 4.01 and
10.01pH.
To change the buffer set, turn off the unit, then press and hold the
“STAND” key while turning on the unit again.
[Note: There is no need to repeat this procedure every time the unit
is power up unless one decides to change the buffer settings.]
B. pH Calibration
The 6010M uses 2-point calibration. The first point must be
6.86/7.00, and the second point can either be 4.00/4.01 or 9.18
/ 10.01.
[
Note:
For accurate measurements, it is recommended that pH
calibration is preformed once a week and after replacing the
electrode.
a.
Calibration with an ATC/Temp probe in the pH-AUTOLOCK
mode.
1.
Turn the unit on. Press “CLEAR/ENTER” key for
5 seconds,
all LCD elements will lit up. The meter clears all calibration
values stored in the
internal memory.
2.
Connect the pH electrode to the BNC connector and the
ATC/Temp probe to the ATC/Temp connector of the unit:
“ATC” icon will lit up. “pH” icon and “AUTO” icon will lit up.
The “STAND” icon will flash.
3.
Rinse the pH and ATC/Temp probes in distilled water and
immerse them in the first buffer solution (either 7.00 or 6.86).
Allow temperature reading to stabilize, then press and hold
“STAND” key for 2 seconds to calibrate. The “WAIT” icon will
flash until the unit detects a stable reading. Once the unit
calibrates the first point, the “SLOPE” icon will flash. The unit
is ready to be sloped at the second buffer.
4.
Rinse the pH and ATC/Temp probe in distilled water and
immerse them in the second buffer solution (either 4.00/4.01
or 9.18/10.01). Allow temperature reading to stabilize, then
press “SLOPE” key to calibrate. The “WAIT” icon will flash
until the unit detects a stable reading. Once the unit
calibrates the second point and the unit will automatically
