To Standardize the meter in the Automatic Standardization Mode
1. Insert the DO probe into a BOD bottle containing about 1 inch of
water.
2. Touch STD on the DO or BOD Measure screen to access the
standardized screen
3. Touch clear to delete a previous standardization.
OR
If the screen says “Not standardized” proceed to step 4.
4. Touch
std again to standardize the meter using this buffer. The
word MEASURING will flash until the signal is stable. The meter
will accept the value once it recognizes that the reading is stable.
At that time, STABLE will appear on the screen at this time. A
beaker icon and the entered DO value will also appear on the
screen at this time. The meter will then return to the measure
screen.
Allow the probe to warm up for 30 minutes after connecting it to the
meter, and prior to standardization.
Once standardization is set, it will be applicable in other modes.
