Influencing Variables Of The Spectral Sensitivity; Steps For Commissioning; Check And Replace Batteries - sauter SP 200K Instruction Manual

1. LCD Display: 3 ½ Digits with maximum reading value until 1999.

2. ON/OFF: With this button the luxmeter is switched on/off.

3. Hold key: With this key the current measured value can be fixed. The meter will

not display new readings until the HOLD key is pressed again.

4. Range: This key is used to switch between the measuring ranges 200Lux/20FC;

2.000Lux/200FC; 20.000Lux/2.000FC; 200.000Lux/ 20.000FC

5. Lux/FC Unit Button: Press this button to switch between the Lux or Foodcandle

(FC) unit.

6. photo sensor

7. Cover for sensor: Used to protect the photodiode when the light meter is not in

use.

5 Influencing variables of the spectral sensitivity

As for the photo sensor: the photodiode used with filters almost reaches the C.I.E.

(International Commission on Illumination) standard of spectral sensitivity test

characteristics. The photometric curve V ( ) is shown in the following table:

1. Power button: The power button is used to turn the light meter on and off.

2. Selection of the Lux/FC scale: Press this button to select the desired light

measurement unit.

3. The photo sensor cover must first be removed and the photo sensor is then held

against the light source in a horizontal position.

4. The nominal value of the illuminance can now be read from the LCD display.

5. Measuring range exceeded: If the device 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 button is pressed to enter the HOLD mode. The

luxmeter stops all further measurements. When this key is pressed again, this

command is cancelled and the instrument returns to normal operation.

7. After all measurements have been completed, the protective cap of the photo

sensor must be replaced.

8. Switch off the device.
