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) solu-
tion for SM801 and 1500 ppm
(M10442) solution for SM802.
For performing EC calibration,
use 1413
µ
S/cm (M10031) so-
lution 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 dis-
play 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 cali-
brated.
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 auto-
matically switches off.
Battery replacement must only take place in a non-
hazardous 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 in-
serting the cover.
