One Check - Three Results
Flicker Factor
Whenever a minimum of light-flicker is required or actual values of the light in the operating area shall be evaluated, the P.R.O.F. delivers the correct answer: |
| - |
direct check of light |
| - |
very fast test of flicker factor (abt. 5 sec.) |
| - |
easy handling (small hand-held optical meter) |
| - |
suitable for Lighting in: |
| |
• |
Film-, TV- and
Videowork |
| |
• |
Cinema- and Projection |
| |
• |
Labs and Workshops for Lighting |
Line Frequency
Whenever Flicker is caused by AC operation the measurement is used to calculate the supply frequency.
|
Illumination
Shows Illumination of an illuminated area in dependence on
the distance. Lux and foot-candle are indicated.
For more precise measurement two different operation modes (daylight/tungsten ) can be selected manually.
Large measuring range due to three measuring ranges that switch over automatically. |
| - |
Simultaneous measurement of flicker, frequency and illumination |
| - |
Power save down mode after 3 min. and complete cut off after 5 min. for extended battery life. |
