MEASUREMENT PROCEDURE

Turn the meter on by pressing ON/OFF.
When the LCD displays “- – -”, the meter is ready.
Fill the cuvet with 10 mL of sample, up to the mark, and replace the cap.
Place the cuvet into the holder and ensure that the notch on the cap is positioned securely into the groove.
Press ZERO and “SIP” will blink on the display.
After a few seconds the display will show “-0.0-”. The meter is now zeroed and ready for measurement.
Remove the cuvet. Open it.
Add 8 drops of Fe-0 reagent and shake gently.
Reinsert the cuvet into the holder and ensure that the notch on the cap is positioned securely into the groove.
Press and hold READ for 3 seconds and the display will show the countdown prior to the measurement.
Alternatively, wait for 5 minutes and just press READ. In both cases “SIP” will blink during measurement.
The instrument directly displays concentration in mg/L of iron.

Interferences

Alkalinity above 1,000 mg/L (CaCO3) will slow down color development. To resolve this neutralize the sample with diluted HCl.
Calcium (Ca2+) above 1,000 mg/L (CaCO3)
Magnesium (Mg2+) above 10,000 mg/L (CaCO3).
Molybdate, Molybdenum above 25 mg/L
High Sulfide (S2+) concentration.
Silica (SiO2) above 100 mg/L may slow down color development.

GUIDE TO DISPLAY CODES

This prompt appears for 1 second each time the instrument is turned on.

The dashes “- – -” indicates that the meter is in a ready state and zeroing can be performed.

Sampling In Progress. Flashing “SIP” prompt appears each time the meter is performing a measurement.

“-0.0-”, the meter is in a zeroed state and measurement can be performed.

The blinking “BAT” indicates that the battery voltage is getting low and the battery needs to be replaced.

“-bA-”, the battery is dead and must be replaced. Once this indication is displayed, the meter will lock up.
Change the battery and restart the meter.

“Conf”, the meter has lost its configuration. Contact your deale or the nearest Milwaukee Customer Service Center.

ERROR MESSAGES

On zero reading

Blinking “-0.0-” indicates that the zeroing procedure failed due to a low signal-to-noise ratio. In this case press ZERO again.
“no L”, the instrument can not adjust the light level. Please check that the sample does not contain any debris.
“L Lo”, there is not enough light to perform a measurement. Please check the preparation of the zero cuvet.
“L Hi”, there is too much light to perform a measurement. Please check the preparation of the zero cuvet.

On sample reading

“-SA-”, there is too much light for the sample measurement. Please check if the right sample cuvet is inserted.
“Inv”, the sample and the zero cuvet are inverted.
“ZErO”, a zero reading was not taken. Follow the instruction i the measurement procedure for zeroing the meter.
Under range. A blinking “0.00” indicates that the sample absorbs less light than the zero reference. Check the procedure and make sure you use the same cuvet for reference (zero) and measurement.
A flashing value of the maximum concentration indicates an over range condition. The concentration of the sample is beyond the programmed range: dilute the sample and re-run the test.

BATTERY REPLACEMENT

Battery replacement must only take place in a nonhazardous environment.
Simply rotate the battery cover on the back of the meter.

Detach the battery from the terminals and attach a fresh 9V battery while paying attention to the correct polarity. Insert the battery and replace the cover.
