Page 3: Preliminary Examination
GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION GENERAL DESCRIPTION HI 9835 is a waterproof portable microprocessor-based Conductivity/ TDS/NaCl/temperature meter. The autoranging feature of the EC and TDS ranges automatically sets the meter to the scale with the highest possible resolution. The measurements are automatically (ATC) or manually (MTC) compen- sated for temperature. -

The sleeve holes must be completely submerged. Tap the probe repeatedly to remove any air bubbles that may be trapped inside the sleeve. -
Page 8: Autoranging
AUTORANGING AUTORANGING AUTORANGING AUTORANGING AUTORANGING The EC and TDS scales are autoranging. The meter automatically sets the scale with the highest possible resolution. By pressing ALT+FIXED, the autoranging feature is disabled and the current range is frozen on the LCD. "F1" symbol blinks on the LCD. -
Page 9: Ec/Tds Calibration
EC/TDS CALIBRATION EC/TDS CALIBRATION EC/TDS CALIBRATION EC/TDS CALIBRATION EC/TDS CALIBRATION Calibration is a 1-point procedure. Selectable calibration points are: 0.0, 84.0µS, 1413µS, 5.00mS, 12.88mS, 80.0mS,111.8mS. To enter EC calibration select the EC range and press the CAL key. Note: TDS reading is automatically derived from the EC reading and no specific calibration for TDS is needed. -
Page 10: Nacl Calibration
In order to minimize any EMC interference, use plastic beakers. The meter uses 1.90%/°C compensation factor during calibra- tion. If the setup item "tc" has been set to a different value, when exiting the calibration mode the value displayed on the upper LCD could be different from the nominal buffer value. -
