Pocket Luminometer industrial field illuminance measurement 200klx
1.Summarize
HUATEC LX-100 Pocket Luminometer Meter is a high-precision, low power consumption, small size, stable performance, easy to use, portable, it mainly used in industrial field illuminance measurements
2.Characteristic
1, Wide measurement range, fourth gear ten times the measure range
switch automatically;
2, low power consumption, 9V laminated cell power-up, low-voltage
directives;
3, the detector V (λ) to amend a high level, reaching the national
level meter requirements;
4, four liquid crystal display and the angle of field view larger
than 60 degrees;
3.The basic principles
Instrument mainly consist of detector and the secondary instrument.
Photometric testing of various physical quantities affect the
precision of the key is the light sensitivity of detector response
curve of the human visual system function V (λ) amendments.Due to
the silicon photovoltaic cells have a long-term stability and life,
so it is widely used in the photometric test, but the spectral
sensitivity of silicon photovoltaic cells to respond to the
standard curve and CIE1931 human visual function V (λ) have greater
difference.The international community generally use a specially
designed color filter to amend the curve,the amendment level
directly affects test accuracy of the instrument.The detector V (λ)
to amend a high level, reaching the national level requirements of
meters.The structure diagram shown in Figure 1.
Photometric signal tested is generated by V (λ) detector to receive and convert into a photocurrent, photocurrent will amplify after converted into a voltage signal and then the module into a digital quantity, was read into the microprocessor.Microprocessor gets preload data multiplied by the scaling factor that is to be the final measurement results.Figure 2 shows the instrument block diagram.
4.Technical indicators
1, measuring range: 1lx ~ 200klx;
2, measurement accuracy: 1;
- Display Refresh Rate: 1 times / sec;
4, Power Supply: 9V laminated battery;
5, power consumption: <20mW;
6, working environmental conditions: Temperature 0 ~ 40 ℃,
humidity: "90%;
7 meter Size: 130mm × 65mm × 25mm;
5. Use instructions
1, installed the battery meter, open the instrument power switch;
2, connected to the light intensity V (λ) probe, open the probe
cover will be placed in the measured probe position;
3, instrument displays the data shall be the location of the light
degrees, the display window on the right of the arrows is the unit
of "lx", or "klx", when the signal overflow, the window displays
"-oL-";
4, when the battery is low, indicating the bottom left corner of
low-voltage arrows; when the battery is running out, the display
window displays the "batt", prompted the need to replace the
battery in order to work;
5, instrumentation should promptly after the shutdown, if the
continuous operation for about 30 minutes later, there is no
shutdown, will automatically shut down.
6. Notes
1. Should pay attention to maintaining the detector surface clean,
do not use should be promptly stamped with the probe cover;
2. Instrument with the detector is equipped with one to one
replacement of the probe to be re-calibration after the device;
3. Do not use instruments should be promptly shut down, power
should be enough time to replace the battery, a long time when not
in use, should remove the battery.
