INTRODUCTION

The Sper Scientic UVA/B Light Meter (Model 850009)

is a light-weight, portable instrument that measures

damaging UV (ultraviolet) light in both natural and

manmade environments.

The UV Light Meter measures long and medium

wave UV-A/B light for applications such as forensics,

chromatography, electrophoresis and dermatology.

You can use the meter almost anywhere to determine

UV light intensity and avoid the harmful e󰀨ects of

overexposure.

BASIC FUNCTIONS

Power On/O󰀨

1. Press and hold the HOLD button for 2 seconds to

turn the meter on. All symbols on the LCD will appear

for 1 second.

2. Press and hold the HOLD button for 2 seconds to

turn the meter o󰀨. All symbols on the LCD will appear

for 1 second. Release HOLD button.

Reading the LCD Display

1. The primary display indicates measurement value

(also referred to as the “average” value).

2. The secondary display indicates the advanced

functions or data recording (minimum or maximum

reading of the current data set) or your one of your

20 recorded data points.

Meter Function Flow Chart

1. Press MODE to choose the main function

(MAX/MIN/AVG, Zero, Unit, Type or Time). MAX/MIN/

AVG Mode is Normal Mode for this meter and has

several sub-functions as indicated in the diagram on

the next page.

MODE AND UNIT SELECTION

Mode Selection

1. Press MODE continuously to cycle through MAX/MIN/

AVG, Zero, Unit, Type, and Time Modes, respectively.

Maximum, Minimum and Average/Normal/Current Mode

1. Press MODE continuously to cycle through modes

until you reach MAX/MIN/AVG.

2. The current measured value appears on the

primary display.

3. The primary reading always displays value of measuring.

The secondary reading displays the outcomes of the

advanced functions or data recording. There ar four

modes of measuring functions. Press Sbutton to change

the mode of measuring: None - Max - Min - Avg.

4. Maximum, minimum and average values will appear

and freeze on the secondary display and will update

only when a new maximum, minimum, or average value

is reached on the primary display. Then the secondary

display updates automatically. The average value on the

secondary display updates according to the detected

maximum and minimum values of the current reading.

5. The Max-Min-Avg values can only be recalled if you

saved each point to the memory. Press Mto save the

current, max, min, or avg value for each data point and

the meter will move to the next data point. The stored

data can hold either one current, max, min, or avg value

for each data point.

6. Press S to reset.

Data Hold

1. While in Normal Mode, press HOLD to freeze the

secondary display value. “HOLD” will appear on the

bottom left corner of the LCD.

2. Press HOLD to cancel Hold Mode.

Zero Adjustment

1. Press MODE continuously to cycle through modes

until you reach Zero Mode.

2. Cover the sensor. If the main display has a reading

other than zero, perform the zero adjustment.

3. Cover the sensor and press S to zero adjust. The

secondary display indicates the adjustment value

for your reference.

4. Press and hold Sfor 1 second to clear the

adjustment value.

Note…

When the adjustment value is over 10 µW, the

measurement value cannot be o󰀨set. The main display

will show the above range reading, and the secondary

display will show “-Err.” Repeat the zero adjustment

procedure or contact Sper Scientic.

5. In Zero Mode, press M to clear data points 0 to 20.

Unit Selection

1. Press MODE continuously to cycle through modes

until you reach Unit Mode.

2. Press S to choose the unit of measure: µW/cm2or

mW/cm2.

Type Selection

This function is reserved for use in future models.

MEMORY

Manual Recording

In Normal Mode, press Mto store the current value that

appears on the primary display. The ashing DATA

(01 to 20) icon stops ashing for 2 seconds and moves to

the next storage location. (Refer to Maximum, Minimum

and Average/Normal Mode on pages 10-11 for instructions

on saving max, min, and avg values.)

Auto Recording

To utilize auto recording, you must rst set an interval time

for recording measurement values.

Interval Time Setting

1. Press MODE continuously to cycle through modes

until you reach Time Mode.

2. Continuously press Sto select an interval time for

auto recording of 1, 2, 5, 10, 30 seconds or

1, 3, 5, 10 minutes.

To Auto Record:

1. In Normal Mode, press and hold M for 2 seconds.

“AUTO” appears next to “REC” on the LCD. As soon as

the meter reaches 20 data points, the unit will turn o󰀨.

Recorded data includes: Irradiation intensity,

Max/Min/Avg and unit of measure

2. Press M to cancel Auto-Record Mode.
