This indicates that the meter has lost its configuration.
• Press ZERO and “SIP” will appear on the display. b) on sample reading: There is too much light for the sample measurement. Please check if the right sample cuvet is inserted. • Wait for a few seconds and the display will show “-0.0-”. Now the meter is zeroed and ready for measurement. The sample and zero cuvet are inverted. A zero reading was not taken. Follow the instruction described in the measurement procedures for zeroing the meter.
TIPS FOR AN ACCURATE MEASUREMENT POTASSIUM HIGH RANGE SPECIFICATIONS The instructions listed below should be carefully followed during testing to ensure best accuracy. 20 to 200 mg/L 5 mg/L ±30 mg/L ±7% of reading ±5 mg/L Tungsten lamp with narrow band interference filter @ 610 nm Adaptation of the Turbidimetric Tetraphenylborate method. The reaction between Potassium and reagents causes turbidity in the sample.
• Press ZERO and “SIP” will appear on the display. • Wait for a few seconds and the display will show “-0.0-”. Now the meter is zeroed and ready for measurement. • Remove the cuvet and add the content of one packet of HI 93750B reagent. Replace the cap and mix gently for one minute by turning slowly the cuvet upside down. • Reinsert the cuvet into the instrument. • Whenever the cuvet is placed into the measurement cell, it must be dry outside, and completely free of fingerprints, oil or dirt.
OPERATIONAL GUIDE POTASSIUM MEDIUM RANGE SPECIFICATIONS POWER CONNECTION Plug the 12VDC adapter (HI 710005 - 110VDC, or HI 710006 220VDC) into the DC socket. Plug the adapter into the outlet. Alternatively, remove the battery cover on the back of the meter; attach 2 fresh 9V batteries and replace the cover. Note: Insure the main line is surge protected. Note: Always turn the meter off before unplugging it to insure no data is lost. MEASUREMENT PROCEDURE • Turn the meter on by pressing ON/OFF.
• Press ZERO and “SIP” will appear on the display. • Wait for a few seconds and the display will show “-0.0-”. Now the meter is zeroed and ready for measurement. • Remove the cuvet and add the content of one packet of HI 93750B reagent. Replace the cap and mix gently for one minute by turning slowly the cuvet upside down. Note: in the following measurement sections, a generic "P– –" will be placed on the secondary LCD instead of the exact related message (e.g. "P1" for Ammonia LR).
INTRODUCTION POTASSIUM LOW RANGE THE ROLE OF NUTRIENTS IN THE GROWTH AND PRODUCTION OF PLANTS SPECIFICATIONS The three elements that are mostly needed by the plants are nitrogen (N), phosphorus (P) and potassium (K). They are called the macronutrients while other elements, needed by plants in smaller amounts, are called microelements. In hydroponics, plants need a balanced nutritive solution, composed of macro and microelements.
PHOSPHORUS • Wait for a few seconds and the display will show "-0.0-". Now the meter is zeroed and ready for measurement. • Remove the cuvet. PRESENT IN ACTION 0 1 x • Add 10 drops of HI 93706A Molybdate reagent. Phosphorus (P) has an important role in many fundamental biochemical and physiological processes. Plants take up phosphorus in the form of phosphate ion (PO43-). • Add the content of one packet of HI 93706B-0 Phosphorus Reagent B (Amino Acid) to the cuvet.
EXCESS EFFECTS • reduced absorption of calcium and magnesium • increase of water consumption • increase of the substrate salinity IRRIGATION WATER (LOW RANGE) In agricultural areas it is quite common to find altered values in the chemical composition of irrigation waters. The problem concerns mostly the high nitrate concentration, usually determined by excessive fertilization or irrational liquid manure spreading.
• Wait for a few seconds and the display will show "-0.0-". Now the meter is zeroed and ready for measurement. • Remove the cuvet. LIST OF MATERIAL 0 1 x • Add 10 drops of HI 93706A Molybdate reagent. SAMPLE PREPARATION • Add the content of one packet of HI 93706B-0 Phosphorus Reagent B (Amino Acid) to the cuvet. Replace the cap and shake gently until dissolution is complete. • Reinsert the cuvet into the instrument.
PHOSPHORUS MEDIUM RANGE • Mix well using the spoon and then wait for 5 minutes. SPECIFICATIONS r l i t f e i c s d • Unscrew the filter assembly, put a filter disc inside and close it again. Range Resolution Accuracy Typical EMC Dev. Light Source Method • Connect the filter assembly to the 60 mL syringe by the screw rim. 0.0 to 50.0 mg/L 0.5 mg/L ±2.5 mg/L ±4% of reading ±0.
• Wait for a few seconds and the display will show "-0.0-". Now the meter is zeroed and ready for measurement. • Remove the cuvet. • Replace the cap and shake gently for at least 2 minutes. 0 1 x • Add 10 drops of HI 93706A Molybdate reagent. • Remove the cap and fill the Demineralizer Bottle with tap water. • Add the content of one packet of HI 93706B-0 Phosphorus Reagent B (Amino Acid) to the cuvet. Replace the cap and shake gently until dissolution is complete.

• Remove the cuvet and add the content of one packet of HI 93728 reagent. • Replace the cap and immediately shake vigorously for exactly 10 seconds by moving the cuvet up and down. Continue to mix by inverting the cuvet gently and slowly for 50 seconds, while taking care not to induce air bubbles. A deposit remains, but this does not affect the measurement. Time and way of shaking could sensitively affect the measurement. • Reinsert the cuvet into the instrument, taking care not to shake it.
