MAKING REDOX(ORP) MEASUREMENT:
9.1
Disconnect and remove the pH electrode and temperature probe.
Connect with a Redox/ORP electrode. Temperature has no effect
on ORP readings and therefore is not require during measurement.
9.2
Rinse the sensor in distilled water then in the test liquid. Stir to
remove bubbles and wait for a stabilized reading.
9.3
Press the
MODE
button once to switch display to
mV
reading.
9.4
Press the
READ
button once and display will show
AutoLock
symbol
blinking, indicating meter is sensing an endpoint reading.

When the
AutoLock
sign stops with short beep, an endpoint reading

9.6
Depend on the liquid that is measured, some volatile liquid may
take up to 20 minutes or even longer time to stabilize. Disable the
Auto-lock (Page4) and Auto-Off (Page6) features. Then endpoint
reading should determine by individual experience in each case.
DATA MEMORY:
