Put on anti-collision hood to provide better protection. There is no need to remove
hood even during calibration.
Step 1
Press the power on key. Select fast or slow. The D.O. will be displayed on the LCD
with mg/I unit.
Two D.O. Activation modes are provided: Slow and Fast. Meter is default at Fast but it
is programmable in setting mode P6.4 (page 13)
•
If D.O. probe is unplugged from meter and not in use for long time, it might take
about 10 minutes to activate.
•
If D.O. probe is plugged on meter for most of time, to set the activation mode to
Fast can make the reading stabilized in few seconds. The disadvantage of Fast
mode is electrolyte consumption is much higher so the need to refill and doing
probe maintenance is frequent.
•
If D.O. probe is plugged on meter for most of time, to set the activation mode to
Slow can make the reading stabilized in 10 minutes. The advantage of Slow
mode is electrolyte consumption is lower and less maintenance work to do.
Step 2
Run 100% calibration in air. (Refer to pg. 18)
Step 3
Switch from % to mg/L then dip the probe into the sample. Making sure the electrode
tips is totally immersed when you stir it.
