340-1000mm Visible Spectrophotometer

Specifications

Description:

1). The instrument work, must be preheated can be measured only 20 minutes
2).Wavelength selection, turn the wavelength window display, adjust to the need of test wavelength
3). Set up the test mode, press the function key, can switch test mode (A: Abs absorbance, T: Trans light transmittance, C: Conc: concentration
4). After get the test result, press the "print" button to print the results
5). Zero (0% T)
Put the occulter into the sample frame, and pull the rack lever makes it into the light path, and then 0% instrument of "T" button, can complete the zero.
Note:
A: zero time road must be put into gear, the zero block, otherwise unable to complete zero, showing "E01"
B: don't open the sample chamber cover
C: zero in transmittance mode according to the "00.0", in absorbance mode shows "1 -", which is beyond the scope display
6). Adjust the (100% T)
A: Can't block zero block into the light path, otherwise cannot be the best, show "E02"
B: don't open the sample chamber cover hundreds
C: in absorbance mode is shown as "000", in transmittance mode is shown as "100.0"
7). The absorbance measurement
1. According to the "key" to switch to the light transmittance measurement model
2. Adjust the test wavelength
3. Placement window, press the "T" 0% to zero
4. Click "function key" to switch to the absorbance measurement model
5. Put reference sample, press the "T" 100% and instrument shows "000".
6. Placement test samples, read the test data
7. Measured values more than 1.999, shows "1 -" which is beyond the scope display
8. When the measured value is lower than 1.999, showing "1 -" which is beyond the scope display
8). Light transmittance test
1. According to the "key" to switch to the light transmittance measurement model
2. Adjust the test wavelength
3. Placement window, press the "T" 0% to zero
4. Placement reference sample, press the "T" 100% best, instrument display "100.0"
5. Placement test samples, read the test data
6. Measured values more than 199.9, shows "1 -" which is beyond the scope display
9). Standard concentration measurement
