OPERATIONAL GUIDE Power connection Plug the 12VDC adapter (HI710005 or HI710006) into the power supply socket (#10 on page 4; #9 on page 6). Note: make sure the main line is protected by a fuse. Probe connection Connect the conductivity probe to the socket provided (#11 on page 4; #10 on page 6). Note: Make sure that the instrument has been calibrated before taking conductivity measurements (see calibration paragraph). Note: If possible, use plastic beakers to minimize EMC interferences.
PROCEDURE FOR EC 214: 0 703 HI If you are measuring in the mS ranges, calibrate the meter using HI7030 (or HI8030) conductivity solution (12.88 mS @ 25 C) or HI7034 (or HI8034) conductivity solution (80 mS @ 25 C). For the µS ranges, use HI7031 (or HI8031) conductivity solution (1413 µS @25 C) when calibrating in the range from 0 to 1999 µS or HI7033 (or HI8033) conductivity solution (84 µS @ 25 C) when calibrating in the range from 0 to 199.9 µS.
• Select the appropriate range: "199.9 µS" for HI7033/HI8033, "1999µS" for HI7031/HI8031, "19.99 mS" for HI7030/HI8030, "199.9 mS" for HI7034/HI8034. Note: If the display shows "1", there is an over-range condition. Select the next higher range. • Allow a few minutes for the reading to stabilize and adjust the “CALIBRATION” knob to read (on the LCD) the value of the buffer solution at 25 C (77 F),e.g. 12.88 mS/cm.
DETERMINATION OF THE TEMPERATURE COEFFICIENT OF A SOLUTION (EC 215 & EC 215R) • Immerse the probe into a sample of the solution and adjust the “TEMPERATURE COEFFICIENT” knob to 0% (i.e. no compensation). • Condition the sample and probe at 25 C and note the conductivity reading C25. • Condition the sample and probe to a temperature t C which is approximately 5 C to 10 C different from 25 C and note the conductivity reading Ct.
