SAUTER SP 200K Internal Sensor Digital Light Meter Instruction Manual

General information

This digital illuminance meter is a precision instrument for measuring the illuminancein 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 silicon diode with a long lifetime

Functions

• FC (foot candle)
• High accuracy and fast response
• Peak-Hold function for the acquisition of peak values
• Unit and number display for easy reading
• Automatic zero setting
• Non-standard light sources are automatically corrected
• Short rise and fall times
• also suitable for LED lighting

Function keys and part names

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.

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:

Steps for commissioning

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. Theluxmeter 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.

Check and replace batteries

1. As soon as a sufficient power supply is not ensured, the symbol appears on the LCD display and a battery change with a 9V block battery is necessary.
2. For this purpose the device must be switched off. The battery compartment cover on the back of the instrument is opened by simultaneously pressing and sliding it in the direction of the arrow.
3. The battery is removed from the housing and replaced by a new 9V block battery.
4. Then the battery cover is reattached.

Maintenance

1. The white protective cap on the photo sensor should be wiped with a damp cloth from time to time.
2. The Light Meter should not be stored at excessive temperature or humidity.
3. The respective period of time for a calibration of the photo sensor varies with the working operations. In general, the light sensitivity decreases directlyproportional to the product of the light intensity of the working time.

To maintain the general accuracy of the instrument, periodic calibration is recommended.
