OPERATIONAL GUIDE
CONNECTIONS
Plug the 12 VDC adapter into the power supply socket.
Note: This instrument use non volatile memory to retain the calibration
parameters and all the other settings even when unplugged.
Connect the EC/TDS probe to the 7-pin connector. Tighten the threaded ring.
Make sure the probe sleeve is properly inserted, as shown below:
INSTRUMENT START-UP
• Turn the instrument on by pressing the ON/OFF switch.
• All LCD tags are displayed and a beep is generated while the instrument
performs self test.
TAKING MEASUREMENTS
Immerse the probe into the solution to be tested. The sleeve
holes must be completely submerged. Tap the probe repeat-
edly to remove any air bubbles that may be trapped inside
the sleeve.
If needed, press RANGE repeatedly until the desired range (EC, TDS, NaCl) is
selected on the LCD (displaying µS[mS], ppm[g/L] or %).
Allow for the reading to stabilize. The upper LCD displays the measurement in
the selected range, while the temperature is displayed on the lower LCD.
