Hanna Instruments HI 98188 Instruction Manual page 13

Notes:
• If the meter displays the top of the range blinking, the reading is out of
range.
• If the stability indicator " " blinks, the reading is unstable.
• Make sure the meter is calibrated before taking measurements.
• If measurements are taken successively in different samples, for accurate
readings it is recommended to rinse the probe thoroughly with deionized
water before immersing it into the samples.
• TDS reading is obtained by multiplying the EC reading by the TDS factor,
which has a default value of 0.50. It is possible to change the TDS factor
in the 0.40 to 1.00 range by entering setup mode.
The probes designed to work with this instrument have an internal ID
identificatior. Every time the instrument detects probe changing, it warns the
user to update the cell constant according with the new probe and then
calibrate the EC range.
