OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE OPERATIONAL GUIDE INITIAL PREPARATION Each meter is supplied complete with a 9V battery. Slide off the battery compartment cover on the back of the meter (see page 18), install the battery while paying attention to its polarity. Connect the probe to the DIN socket on the top of the meter by aligning the pins with the socket and pushing in the plug.

(HI 7004 or HI 8004) if you are going to measure acidic samples or pH 10.01 (HI 7010 or HI 8010) for alkaline measurements. If you need to calibrate HI 9812 and HI 9813 to NBS standards, use pH 6.86 (HI 7006 or HI 8006) instead of pH 7.01 and pH 9.18 (HI 7009 or HI 8009) instead of pH 10.01.
• Select the appropriate range, e.g. µS/cm for HI 9812 or the mS/ cm key for the HI9813. • Turn the EC/TDS calibration knob until the display shows the EC or TDS reading at 25°C.

The TDS value in aqueous solutions is directly proportional to conduc- tivity. The ratio between the two parameters depends on the solution. HI 9812 has a fixed conversion factor set to 0.5 (corresponding to a solution of CaCO ). This means that 1 µS/cm is equal to 0.5 ppm (mg/L) of TDS.
