5.2 pH Electrode Diagnosis Indicator

There is an electrode diagnosis icon that indicates the condition of pH
electrode being used.

The STABLE icon will appear once the reading is stabilised. If the
meter is calibrated with 2 or more points, then meter displays the
electrode characteristic indicator bar with appropriate segments.

All 3 segments lighted:

102% < Slope < 90%

2 segments lighted:

90% < Slope < 80%

1 segment lighted:

80% < Slope < 70%

None lighted:

Slope < 70%

mV measurement (absolute)
Press the mode to go to the mV measurement mode. Meter displays
the current mV value with stable icon if the reading is stable.

REL mV measurement
Press the mode key to select the REL mV measurement mode.
Meter displays the REL mV value if the meter has already been
standardized. Otherwise it displays the absolute value of the oRP
solution.

Temperature measurement

If the temperature probe is not connected then meter displays 25°C in
pH1500 model or manually adjusted temperature value in pH 1500
and default icon on the secondary display.
If the temperature probe is connected then meter senses the actual
temperature and displays it with ATC icon.

Memory in/ Recall functions
While in the measurement mode, by pressing the key will store the
displayed data in the non-volatile memory.

While in the measurement mode, by pressing the key will retrieve
data from the non-volatile memory on last in first out basis. (LIFO)

By pressing enter key user can scroll through the rest of the memory
locations.

Serial communication interface (RS232)

Meter will be able to communicate with PC which has the user
interface software installed. Serial printer can also be connected to
the meter to get the print out of the current displayed data or data
stored in the memory by pressing enter/ print key.

Error messages

Err: Communication receive buffer is overflowing
Err1: Communication error due to baud rate/ parity/ frame/ stop
Err2: More than 6 points pH calibration
