MEASUREMENT PROCEDURES
Conductivity Measurement
The conductivity probe measures 0 ~ 19.99 uS/cm, 0 ~
199.9 uS/cm, 0 ~ 1999 uS/cm, 0 ~ 19.99 mS/cm, 0 ~ 199.9
mS/cm. In Normal Mode, the ATC indicator appears in the
lower right corner of the LCD to indicate Automatic
Temperature Compensation. If you select MTC, the ATC
indicator will disappear. When selecting MTC, you must
first deactivate ATC in P5.1 (page 23) and then set a MTC
value in P5.3 (page 24).
Before measuring, remove the probe cover if needed. To
measure:
1. Rinse the probe with de-ionized or distilled water.
2. Press POWER to turn the meter on. Press MODE to
select CON measurement. Before measuring, set the
temperature coefficient (P5.4 on page 24).
Note…
Reference temperature or Tref (page 63) of the meter is set
at 25°C and CANNOT be adjusted.
3. Immerse the probe tip (glass bulb) completely into the
sample.
4. Stir the probe gently to create a uniform sample.
5. Wait until the reading has stabilized. If enabled in setup,
“READY” will illuminate to indicate a stable reading.
