2. GENERAL DESCRIPTION

The instrument HT309 is a precision digital luxmeter, mainly used for measuring
illuminance of both white light sources and LED sources of various colours, expressed in
Lux (Lx) or Foot-candles (Fc). The instrument complies with CIE (International
Commission on Illumination) standards on spectrum response and corrects according to
the cosine of the angle of incidence of light. The silicon photodiode sensor guarantees
measurement stability.
The instrument has the following functions:
•
Illuminance measurement up to 400kLux / 40kFc
•
Luminous intensity measurement (expressed in Candles)
•
Selection of the measuring unit: Lx/Fc/CD
•
Light source: white light source and LED sources in their visible spectrum
•
High-precision and rapid measurements
•
Data HOLD function
•
MAX/MIN/AVG functions
•
Zeroing of the displayed value
•
Setting of correction factors of spectrum response
•
Internal memory for saving measurement results
•
Auto Power OFF
•
Autorange

3. PREPARATION FOR USE

3.1. INITIAL CHECKS

Before shipping, the instrument has been checked from an electric as well as mechanical
point of view. All possible precautions have been taken so that the instrument is delivered

IEC6F22 included in the package. In order to prevent battery discharge, it has not been
inserted in the instrument. For battery installation, follow the instructions given in § 5.1.
The " " symbol appears when the battery is flat. Replace the battery by following the
instructions given in § 5.1.

3.3. CALIBRATION

The instrument has the technical specifications described in this manual. The instrument's
performance is guaranteed for 12 months.

3.4. STORAGE
