7.2 Operating position
Free-operating OSRAM DULUX ® S, S/E, D (ES), D/E (XT), T (XT, CONSTANT), T/E (XT, HE,
CONSTANT) lamps are measured in the base-up position, OSRAM DULUX ® L (SP, XT, HE,
CONSTANT), F and CFL SQUARE ® are measured in horizontal operating position. All measurements
are according to IEC.
7.3 Constant photometric values
Aged and stabilised OSRAM DULUX ® lamps provide reproducible photometric data at constant
ambient temperature and in an unchanged operating position. Fluctuations are less than 1 % of the
upper range value.
7.4 Electrical measurements
All the cables, control gear and instruments must be arranged, and if necessary shielded, so that
there is no chance of interference from external fields. Use instruments which will supply the level of
accuracy required in the measured values.
Recommendations
Instruments: Rms instruments (true RMS)
Accuracy: ±0.2% of the measuring range
Area of application
Frequency: 0-500 Hz (CCG) scanning rate
0-400 kHz (ECG) scanning rate
Crest factor: > 2 (CCG)
> 3 (ECG)
Lamp supply: Supply voltage: Depending on the lamp and control gear (magnetic, electronic or
reference device)
Stability: ± 0.2% during the measurement
Total harmonic distortion: < 3%
Suitable supply: – Noise-free mains
– Electronically Regulated stabilisers
– Rotary measuring generators
– Electronic generators
The apparent power of supply unit should be five times the rated system power.
