2. Press "POWER" key to power on. "ATC" icon appears to indicate
automatic temp. compensation while the temp. probe is plugged.
3. Dip the electrode into the sample, the electrode must be completely
immersed into the sample. Stir the probe gently to create a homogenous
sample.
4. Wait until the "READY" icon appears. (Fig. 1)
5. To toggle between pH and mV, press "MODE" key.
ORP Probe- mV Measurement (±1999mV)
Taking ORP (Oxidation Reduction Potential, mV) measurements, the range
is -1999mV to +1999mV. Please remove the electrode soak bottle before
measurement. To take the readings
1. Rinse the probe with de-ionized or distilled water before use to remove
any impurities adhering to the probe.
2. Press "POWER" key to power on the meter and press "MODE" key to
select mV measurement.
3. Dip the electrode into the sample, the electrode must be completely
immersed into the sample. Stir the probe gently to create a homogenous
sample.
4. Wait until "READY " icon appear. (Fig. 2). No need to take Temp.
compensation into consideration when using ORP probe.
Manual Temperature Compensation (MTC)
pH probe
Simply disconnect the Temp. sensor from meter and select the mode as pH. To
set the temperature, press "ENTER" KEY more than 1 second until "CR" flashes
on LCD. Press "p"or "q" key to change the temperature value and press
"ENTER" key to save and return to normal measurement mode.
ORP probe
NO ATC or MTC for ORP probe. It is not necessary to take temperature
compensation into consideration.
Hold Function
To freeze the current readings while in normal measurement mode. To hold
the readings, press "HOLD" key in measurement mode, " HLD "appears on the
display. To release the holding value, press "HOLD" key again. (Fig.3)
