Introduction

The Florite 800 is a battery powered, hand held instrument with a digital LCD

display capable of measuring the velocity, volume ﬂowrate and temperature

of air by means of a thermal probe. The unit allows the airstream area to be

entered for volume measurement. Measurements may be displayed in either

Metric or Imperial units as selected from the keyboard. After selection, this

will be ‘remembered’ by the instrument until reselected from the keyboard. The

attached thermal anemometer probe has a tip diameter of 1/4" (8mm) and is,

therefore, suitable for measurements at grilles, slot diffusers and in small ducts

where large access holes are not acceptable. The velocity sensor in the probe

is compensated for variations in airstream temperature by means of a second

thermistor which also senses, and displays, the actual airstream temperature in

either metric or imperial units consistent with the units selected for velocity.

The instrument is supplied with batteries. Four 1.5 volt ‘AA’ size cells are re-

quired which may be either disposable or rechargeable types. Either Standard

or Alkaline disposable cells may be used but the Standard type will exhibit a

relatively short life and are, therefore, not recommended. Low battery condition

is indicated by ‘LOBAT’ appearing on the instrument display. The cells must be

replaced as soon as possible to maintain optimum accuracy. The battery cells are

accessible by sliding the cover (at th e rear of the instrument case) in the direc-

tion of the arrow. A tape is provided in the battery compartment for easy removal

of the battery cells. Ensure that the battery cells are replaced with the correct

polarity as indicated in each cell compartment. Rotate the cell slightly forwards

and backwards to check that the cell is properly seated in the cell compartment.

FLORITE® 800 INSTRUCTION 16-9013 Installation/Operation/Maintenance Rev. 3 – March 2004 Introduction The Florite 800 is a battery powered, hand held instrument with a digital LCD display capable of measuring the velocity, volume ﬂowrate and temperature of air by means of a thermal probe. The unit allows the airstream area to be entered for volume measurement. Measurements may be displayed in either Metric or Imperial units as selected from the keyboard.

Florite 800 Key Functions Pressing the ON/OFF key will alternately switch the instrument ON and OFF. When ﬁrst turned ON, all display segments brieﬂy light, followed by a countdown from 9 to 0. If LOBAT is lit in the display at this time, then the batteries will need to be replaced before using the instrument. The display will next indicate either velocity or volume ﬂow, and temperature of the probe in the units previously selected.
PAGE 3
Florite 800 This is a dual function key. In either the Velocity or Volume modes, this key allows the unit to be changed sequentially between Metric and Imperial on each key press. In the Area mode, the lower case option is selected which allows the air-stream area to be incremented on each key press or by holding the key down. The ratio of change of duct area will progressively increase, the longer this key is held down. This is a dual function key.

Florite 800 When in the averaging mode, this key displays the maximum, minimum, and average reading during the averaging period. When the averaging period has been stopped, one press will show the maximum vel or vol reading and the maximum temperature reading recorded during that period, together with the Max annunciator. A second press will show the minimum vel or vol reading and the minimum temperature reading recorded during that period together with the Min annunicator.

Florite 800 Where to Use the Instrument Large Areas: When measuring velocity or volume ﬂowrate over a large area, a number of readings must be taken, spaced to give an even coverage of the whole area. The average of these readings will give the mean velocity over the whole area or the mean volume ﬂowrate. It should be noted that quite large variations in readings may be observed and, in general, the larger the number of readings taken, the more accurate the mean velocity (volume ﬂowrate) will be.

Florite 800 HELP Routine: ( Code 11332 ) The unit will display ‘HELP’ for a period of two seconds, and will then display all the display segments with ‘Press Zero’ shown ﬂashing: check that all the display segments are present. Pressing the zero key will move the unit through a series of internal tests. The unit will display ‘PASS’ if it is functioning satisfactorily or display an error message if a test has failed.
