Oil and fat: Rinse the electrode with the HI 7077 or HI 8077

Cleaning Solution.

FLUORIDE ELECTRODE CLEANING

General Rinse the fluoride electrode with deionized water.

Protein, oil Clean the tip of the electrode with a cotton wool

and fat soaked in alcohol. Afterwards rinse with deionized wa-

ter.

IMPORTANT: After cleaning, rinse the fluoride electrode well with

deionized water and dry it attentively with a non-

abrasive cloth.

MALFUNCTIONING

• Reading fluctuates:

Could be due to dirty or blocked reference electrode junction:

follow the cleaning procedure above.

• Reading drifts:

Submerge the tip of the reference electrode in a HI 7082 or

HI 8082 solution at a temperature of 50-60°C for about an hour.

Afterwards, rinse with deionized water.

• No slope (meter always reads the same value) :

Bulb or the stem of the fluoride electrode might be cracked.

Repeat the measurement with a fresh fluoride electrode.

• Response (of the fluoride electrode) is sluggish:

Immerse the fluoride electrode in a HI 70702 solution for 3 hours.

BATTERY REPLACEMENTBATTERY REPLACEMENT

BATTERY REPLACEMENT

When the batteries are run down "LOBAT" is

displayed on the Liquid Crystal Display. In this

case it is advisable to change the batteries as

soon as possible.

Battery replacement must only take place in a

non-hazardous area using alkaline batteries.

In order to replace run down batteries, simply

remove the two screws on the rear cover of the

instrument and replace the four 1.5V AA bat-

teries with new ones, paying attention to the

correct polarity.
