If the meter will not calibrate or displays a -1, reset the meter and attempt to
re-calibrate.
1. Turn off the meter.
2. Remove the battery cartridge from the top of the meter.
3. Press the ON/OFF button for 10 seconds to bleed off all charges within the
meter.
4. Re-insert the batteries and turn the meter on.
5. Follow the pH Calibration procedure.
¬ If the unit appears to be locked (display frozen) it is possible that the Data
Hold mode has been inadvertently accessed by pressing the MODE button.
Press the MODE button again or turn the meter off and restart if the
display appears frozen.
¬ If the meter does freeze and no button presses revive it, remove the
batteries, press the ON button for 10 seconds and then reinsert the
batteries.
¬ If the batteries are removed, any stored readings will be discarded and the
user calibration data for pH will be cleared. New user pH calibration data is
required. However, factory calibration data will be retained.
EXPAND YOUR TRACER
Interchangeable electrodes are available to convert the pH TRACER to a Total
Chlorine TRACER or an ORP TRACER.
Remember to ask for instructions and appropriate reagents or buffer tablets
when ordering the Total Chlorine or ORP electrodes.
Replace electrode. Use bulb guard.
Avoid plunging electrode into bottom of
container and stir bars.
For each 50 mL of sample add 1 drop
(50 mL) of saturated Potassium Chloride
(KCl). No alteration in pH will occur by inert
KCl.
Calibrate with fresh buffers
Calibrate with buffers that bracket sample
pH
Press MODE or turn meter off
Remove batteries press ON/OFF button
for 3 seconds. Reinsert batteries (stored
data will be lost)
