5. mV Measurement:
5.1. Press
key to turn on, and short press
to switch to
mode;
5.2. Connect the ORPC composite electrode or the ion composite electrode (sold
separated),the electrode is washed and dried in pure water and immersed in the
measured solution., slowly stir and then still. When there appear a
“
”
and a
stable reading, that is the value .
6
. Conductivity Measurement:
6.1. Preparation Work:
6.1.1.Press
key to turn on the meter;press
key,choose
measurement
mode.
6.1.2.Check whether the DJS-1.0 conductivity electrode ploe piece is intact. If the electrode
pole piece glass is damaged, the conductivity electrode pole piece rusts will cause
the electrode not to be used normally, so we should replace the new electrode.
6.1.3. Connect the DJS-1 conductivity electrode and temperature electrode into the meter.
6.2. Meter’s Calibration (Standard solution calibration method):
Press
key,
“
”
is flashing on the upper right corner of the LCD, indicate
enters into the calibration mode, wash the DJS-1conductivity electrode with purified
water and dry it, then insert it into the 1413μS/cm calibration solution with temperature
electrode, still it after stirring, Wait for solution stability and
“
”
icon appears,
press
key,LCD shows the current calibrated solution value 1413μS/cm,confirm the
correct solution of the solution at this time, and then press the
key,Save
calibration data and exit the calibration mode according to the
key,at this time,
the calibration indication icon
and
will be displayed at the lower right
corner of the LCD.
