Description
SH2400 is a lightweight, portable, and easy-to-operate light meter
with a 4.3-inch colored touch screen and simple interface keep up with
the times. This product has basic features for fast and easy
measurements for illumination/luminance applications.
Measuring Capabilities: Peak Wavelength, Illuminance/luminance,
Irradiance per wavelength, Color Temperature, CIE x, CIE y, CIE u,
CIE v, CIE 1931, CIE 1976, and CRI.
Six kinds of display mode: INFO, CRI, CIE 1931, CIE 1976,
SPECTRUM, and DATA.
All-in-one light meter: no other equipment is necessary. (e.g. PC
or power supply etc.)
Can be used with the SpectraSmart (OTO software) to interface
with PCs.
※You have to buy additional parts (such as a cosine corrector or a
fiber-collimator) and do standard illuminance/luminance calibrations for ensuring
“Illuminance/luminance” and “Irradiance” values correctly.

calibration and update the intensity table to make the measurement
corresponding to user interface displayed.
Take a Measurement
Press the “Measure” button to measure the light source.
It will take about 3 seconds to measure the light source.
Press “Display mode”buttons on the right to see different
display results.

File saving format and rule
While pressing ”Save”button to save current measurement
data on the SD card with “.SPS”files in Text Format. And system
will construct specified folder and the rule of file naming is
shown as below:
Memory card is New formatted or Never Use on SH
series system:
System will automatically construct the “SPECXXX”
folder and in which XXX.sps files are generated while
saving process. The XXX is 3 digits index assigned by
system started from 000 to 999. Current system defines
maximum 1000 folders (000-999) can be saved and each
folder allows maximum 1000 (000-999) files index. The
number of file index will increase 1 every time when user
executes saving file request. And if the file index reaches
to 999, system will generate a new folder by increasing 1
on folder index name.
Memory card Has Been Used to save files on SH series
System:
System will search the card disk while saving request; it
will find out the largest folder index. Then check the
folder’s .sps file index number. If the file index < 999, it
will save the current .sps file with the new index increase
1. For example, if the last file index is 015, the new saving
files will be 016.sps. But if the file index in this folder has
reached 999, it will construct a new folder with folder
index increase 1 and save file index from 000 in new
folder.
Note. If the disk contains too many dummy files, it will make the
searching process slow.

Fig.12: example of file saving structure
“.SPS”text file and sample format:
This file is a text format but specified for OtO software
“SpectraSmart”saving/loading. The “SpectraSmart”tool saves
measurement data to in “.SPS”format. It also allows user to
load the saved “.SPS”file back and it draws, calculates the
spectrum and color info. SH2400 saves the same format “.SPS”
file to “Spectrasmart”, so the “.SPS”file could be loaded by
software “Spectrasmart”on PC side. The file contains only
spectrometer setting info and raw data of spectrum. The sample
template is shown as below.
