WARRANTY

These instruments are warranted from all defects in
materials and manufacturing for a period of two years
from the date of purchase.

The probes are warranted for a period of six months.
If during this period the repair or replacement of parts

is required, where the damage is not due to negligence
or erroneous operation by the user, please return the
parts to either distributor or our office and the repair will
be effected free of change.

Note: We reserve the right to modify the design,

construction and appearance of our products

PRELIMINARY EXAMINATION

Remove the instrument from the packing material and
examine it carefully to make sure that no damage has
occurred during shipment.

If noticeable damage is found, notify your Dealer.
Each meter is supplied complete with:

• MA850 combination, amplified, double-junction,
gel pH-electrode with incorporated EC/TDS probe
and built-in temperature sensor; 1 m cable

• pH7.01, 1413 µS/cm & 1382 ppm (for SM801) or
1500 ppm (for SM802) solutions, 20 mL each

• 1x9V battery

• Instruction Manual.

OPERATION

Slide off the battery compartment cover on the back
of the meter. Install the battery while paying attention
to its polarity.

Connect the probe to the meter
securely by aligning the pins with
the socket and pushing the plug in.

Always remove the electrode pro­tective cap before use.
Make sure that the meter has been
calibrated before taking any mea­surements.

Turn the instrument on by pressing
the ON/OFF key.

pH MEASUREMENTS

If the probe has been left dry, soak the tip in a pH7
(M10007) buffer solution for a few minutes to reacti­vate it.

Submerge the tip into the sample to be measured,
select the pH mode and allow the reading to stabilize
before taking any measurement.

EC/TDS MEASUREMENTS

Immerse the tip of the probe into the sample to be
tested.

Select the desired measurement range (EC or TDS)
and wait for the temperature sensor to reach thermal
equilibrium with the sample before taking any measure­ment.

AFTER MEASUREMENTS, switch the instrument off,
clean the probe and store it with a few drops of storage
solution in the protective cap.

CALIBRATION PROCEDURE

Remove the protective cap from the probe.
Switch the meter on.
Select the desired range (pH, EC, TDS) by pressing
the appropriate key.

pH Calibration

The instrument can be manually calibrated at one
point for pH.

A) PREPARATION

If the samples to be measured are
neutral or close to neutral pH, to
obtain accurate readings use pH

7.01 buffer solution (M10007). The
pH 4.01 buffer (M10004) is suit­able for acidic measurements,
while the pH 10.01 (M10010) buffer
should be used for alkaline
samples.

B) PROCEDURE

Rinse the tip of the probe and immerse it in the buffer
chosen for calibration. Wait a couple of minutes for
the reading to stabilize.

With an accurate thermometer
measure the temperature of the
buffer solution.

Adjust the calibration knob until the
LCD shows the pH value at the
measured temperature (see the
“pH versus temperature” chart for
reference).

The calibration is now complete and the meter is ready
for use.

EC/TDS calibration

The instrument can be manually calibrated at one point
for conductivity range.

A) PREPARATION

For performing TDS calibration,
use 1382 ppm (M10032) solu­tion for SM801 and 1500 ppm
(M10442) solution for SM802.

For performing EC calibration,
use 1413 µS/cm (M10031) so­lution for both meters.

B) PROCEDURE
Immerse the tip of the probe in the calibration solu-

tion.
Wait for the reading to stabi-

lize, and then turn the EC/TDS
calibration knob until the dis­play shows the EC or TDS
reading at 25°C.

The calibration is now complete and the meter is ready
for use.

Note: Since the conversion between EC and TDS is

made by a built-in circuit, it is request to
calibrate the meter only in EC or TDS range,
and the other range will be automatically cali­brated.

The instrument should be recalibrated at least once a
month, or whenever the probe or battery is changed.

BATTERY REPLACEMENT

The meters are powered by a 9V battery that is
located on the rear of the instrument.

When the battery becomes weak, the instrument auto­matically switches off.

Battery replacement must only take place in a non­hazardous area using an alkaline 9V battery.

Slide off the battery compartment cover and replace
the rundown battery with a new one. Make sure that
the battery contacts are tight and secure before in­serting the cover.
