Insert the mini phono jack of temperature sensor into the socket on the meter.
Unplug the phono jack when not in use or you measure pH without any
temperature compensation.
2.7 Condition the pH Electrode
Condition the pH electrode before use or if it has not been in use for a long time
by soaking it into a container filled with pH 4 buffer solution for at least 1 hour.
Rinse with tap water before proceed to calibrate the electrode with meter.
2.8 Switching the Meter On
1. Press ON/OFF key to power up your meter. All LCD segments display
momentarily as the meter performs a self-diagnostic test, as per shown in
section 2.2. For Ion 5/6, the LCD switches into Ion measurement mode with
“- - -“ display if the meter has not been calibrated or meter has been reset.
2. Press MODE key to choose your desired mode of measurement with its
corresponding annunciator displays in the LCD.
In temperature mode, the measured reading can be 25.0 o C (factory default)
or last calibrated temperature value if there is no temperature probe, or
current measured value if a temperature probe is connected.
3. The LCD displays “Or” if the meter reading exceeds the maximum or “Ur” if
under minimum measurement range (refer to Section 7 on Specifications).
