Instruction manual digital light meter
Congratulations on purchasing this lighting knife from SAUTER. The purchase of this
device once again enables a step forward in the accuracy of measurement technology.
Although it is a complex and very sensitive instrument, it is still very robust and will last
you many years if used correctly. Please therefore read the operating instructions
carefully and keep them within easy reach.
We wish you much pleasure with your quality measuring instrument. For questions,
wishes or suggestions we are always at your disposal.

1 General information
This digital illuminance meter is a precision instrument for measuring illuminance in the
work area. The sensor has a full cosine correction for oblique light incidence. The
instrument is compact, robust and easy to use due to its design. The light-sensitive
component used in this light meter is a very stable, long-life silicon diode.
2 Functions
* The light measuring level ranges from 0.1Lux to
200,000 Lux, 0.01 FC (food candle) to 20,000 FC, in repetition
* High accuracy and fast response
* Peak-Hold function for recording peak values
* Unit and number display for easy reading
* Automatic zero setting
* Non-standard light sources are automatically
corrected
* Short rise and fall times
3 Technical description

Dimensions photo sensor: 100mm x 60mm x 28mm
weight: approx. 250g (5.8 oz)
Accessories: carrying case, operating instructions, battery
4 Function keys and part designation
1st LCD display: 3 ½ digits with maximum reading value until 1999.
2. on/off key: this key is used to switch the luxmeter on or off
3rd Data-PEAK key: Press this key to cancel the peak recording mode.
4th selection key: Press this key to change the selection of 200Lux/20FC;
2,000Lux/200FC; 20,000Lux/2,000FC; 200,000Lux/ 20,000FC (always repeating in a
circle).
5. data- hold key: this key is pressed to fix the current measured value. All further
measurements are stopped by the luxmeter. If the HOLD key is pressed again, this is
cancelled and the unit can take measurements again.
6. lux/FC unit key: Press this key to select between the Lux or Foodcandle (FC) unit.
7. photo sensor

5 Influencing variables of spectral sensitivity
As for the photo sensor: the photodiode with filters used almost reaches the C.I.E.
(International Commission on Illumination) standard of spectral sensitivity test
characteristics. The photo-optical curve V ( ) is shown in the table below:
6 Steps to commissioning
1. on/off button: The on/off button is used to switch the light meter on/off.
2. selection of the Lux/FC scale: Press this key to select the desired light metering
unit.
The photo sensor cover must first be removed and the photo sensor is then held
against the light source in a horizontal position.
The nominal illuminance value can now be read off the LCD display.
5. measuring range exceeded: If the unit only shows a "1" on the display, the input
signal was too strong and a higher range must be selected.
6. data HOLD mode: The HOLD key is pressed to enter the HOLD mode. The
luxmeter stops all further measurements. If this key is pressed again, this command is
cancelled and the instrument returns to normal operation.
7. data PEAK mode: Press the PEAK key to select the peak mode. Once this selection
is made, all subsequent measurements are paused. If the PEAK key is pressed again,
the PEAK-HOLD mode is cancelled and the instrument returns to normal operation.
After all measurements have been completed, replace the protective cap of the photo
sensor and press the off button.
7 Check and replace batteries
As soon as an adequate power supply is not ensured, the symbol appears on the LCD
display and a battery change with a 9V block battery is necessary.
2. switch off the unit to do this. The battery cover is pressed down and at the same
time pushed down in the direction of the arrow to open the battery compartment.
3. the battery is removed from the housing and replaced by a new 9V block battery
4. replace the battery cover.
8 Maintenance
6 SO-BA-e-2020
The white protective cap on the photo sensor should be wiped with a damp cloth from
time to time.
2. the light meter must not be stored at too high a temperature or humidity.
The period of time required for a calibration of the photo sensor varies with the working
operations. In general, the light sensitivity decreases directly proportional to the
product of the light intensity of the working time.
To maintain the general accuracy of the instrument, periodic calibration is
recommended.

Note:
When the protective cap is on the photosensor, the unit always displays "000";
if this is not the case, please operate the adjustable resistor on the back of the
housing.
