Specifications
COMBINATION MODULES NOTES:
1 All values measured after a one-hour warm-up period.
2 Over any one-hour period, half-scale output.
3 Over any 24-hour period, half-scale output.
4 Measured from resulting intensity fl uctuations of a laser diode,
measured optically with a 150kHz bandwidth photo detector.
Measurements made with 1MHz detector are typically 10%
higher.
5 ILX Lightwave model LNF-320 low-noise fi lter option may be
used if lower noise performance is required.
6 Maximum output current transient resulting from normal
operational situations (e.g., power on-off), as well as accidental
situations (e.g., power line plug removal). For more information
request ILX "Transient Test Standards" #LDC-00196.
7 Maximum output current transient resulting from a 1000V
power line transient spike. Tested to ILX Lightwave
Technical Standard #LDC-00196.
8 Maximum monitor photodiode current drift over any 30-minute
period. Constant-power mode stability specifi cation assumes
zero drift in detector responsivity.
9 Output current rated into a 1 Ω load.

11 Software limits of range.
12 Accuracy fi gures quoted for a 10k
Ω thermistor. Accuracy fi g-
ures are relative to calibration standard. Both resolution and
accuracy are dependent on the user-defi ned confi guration of
the instrument.
13 Over any one-hour period at 25°C. Short-term temperature
stability is a strong function of the thermal environment of the
thermistor and TE module. Room air currents in particular can
easily cause fl uctuations of 0.1°C in an exposed mounting con-
fi guration.
14 Over any 24-hour period at 25°C.
