How To
Use the Light Meter 1330 for Orchids

The Light Meter 1330 (or Nicety Lightmeter LM802) is an inexpensive, but reliable light meter for the hobby or professional orchid grower. It can also be used for any other plant, to germinate seeds, in nuseries or whereever a light measurement is needed. It can be used to measure light levels outdoors, in the greenhouse or under fluorescent and high pressure lamps. It can measure the light intensity either in lux or in footcandle.

1) Unpacking the Light Meter and Inserting the Battery

The light meter comes in a black storage case with a red foaminsert. The case contains:

1) The Light Meter 1330B
2) The Light Sensor (closed with a cap)
3) Two screws for the battery compartment
4) A 9V battery
5) A manual for the light meter

Connect the battery and insert it in the battery compartment. Remove one of the small screws from the bag. Store the other screw in the box with the light meter, in case you lose the other one.
Close the battery compartment and secure it with the screw.

The screen of the light meter is protected with a plastic film. Remove this film now.

The light sensor is protected with a black cap. remove this cap and expose the white light sensing area of the light meter.

 

2) Using the Light Meter 1330B

Press the red POWER button to turn the light meter on.

The meter will always turn on in the Lux mode.

Use the LUX/FC button to select the measurement unit Lux or Footcandle.

Lux and Footcandle are two different units for light intensity. 1,000 Footcandle equal 10,760 Lux.

This section only applies for the measurement in LUX:

If the meter displays the number "1" at the left side of the display, the light is to bright for the measurement range selected.

In this case press the RANGE button, the meter will switch in the next higher range and a small "x10" appears in the display.

If the "x10" symbol is visible you need to multiply the number displayed by the factor 10 to get the right Lux number.

Example:

380 x 10 = 3,800 Lux

If the display continues to show the number "1" the light is still too bright, you need to push the RANGE button again. The display now will show a "x100".

Example:

471 x 100 = 47,100 Lux
