Hitachi U-2001 spectrophotometer
Be sure to read Hitachi Spectrophotometer's instruction manual also to ensure Hitachi Spectrophotometer – UV Solutions Program (Operation Manual) This (8) Spectrum display in quantitative measurement Wavelength scan spectra can Hitachi U-2900 UV-Vis Double Beam Spectrophotometer Validation function as standard enables user to check. Instruction Manual for Model U-2810 Spectrophotometer; Maintenance Manual (Part No. 122-9905) Instruction Manual for Hitachi Spectrophotometer Series; UV Solutions Program Operation Manual (Part No. 134-9010) The above manuals describe the operating instructions and precautions for the Model U-2810 Spectrophotometer.
Hitachi U-1000, U-1100 spectrophotometers
Menu in Datalyse
- Measure at one wavelength
- Spectrum, wavelength scan
- Baseline, wavelength scan
- Zerovalue absorbance
Baud rate 4800, evenparity, 2 stop, 7 data bits.No commandfor version.
Wavelength interval:
- U-1000: 325 nm - 1100 nm
- U-1100: 200 nm - 1100 nm
It is possible to measureabsorbance (transmittance and concentration).
Scan:
Hitachi U-1100 cannot scana spectrum, so Datalyse runs through the wavelength interval. The data from thebaseline is placed in column C in the table. Once the baseline has been measured,column C in the table will automatically be subtracted at a scan. If youexperience problems, try reducing the wavelength interval to for instance [400nm; 800 nm] and remember that an ordinary cuvette does absorb light in theUV-area.
Comments:
The cable is a standardnull-modem cable, available in most computer shops.
You cannot tell from thepc if Hitachi is setup to measure absorbance, transmittance or concentration. Ifyou want to measure transmittance you have to setup the device manually andchange the unit from absorbance to transmittance in Datalyse.

Hitachi will beep if itreceives a wrong command! This can happen when you setup the device since it e.g.takes 15 seconds to turn on the UV-lamp and as much as 30 seconds to change thewavelength. Try again. If necessary you can turn the UV-lamp on yourself.
Datalyse sets the deviceup for remote control. But the control is released after each series ofmeasurements.
Datalyse checks if thelamps are lit and will automatically turn the visual lamp on. The UV-lamp is litif the wavelength is set below 350 nm. When the lamps are lit from the pc,Hitachi will turn off when the remote control is released after each series ofmeasurements.
Hitachi U-1000 has notbeen tested in Datalyse! Avoid using wavelengths below 325 nm!

Table measuring
Hitachi U-2001 sends data to the pc regularly andDatalyse writes the results to the table.
List interval is set in the menu instr setupon the Hitachi.
Print format must be set for one set of datafor each line.
A Wave-Length Scan is send with the largestwavelengths first. Use Options / Sort in Datalyse before drawingthe graph.
The cable is a standardnull-modem cable, available in most computer shops.

No version command.
Receive terminator must be CR (not CR+LF).Commands to the device are ended with LF (not CR or CR+LF).
Auto serial output must be ON

See chapter 11 Calibration in the manual.
Remote Control is not used! Unfortunately it ispoorly designed! If you wish, you can try experimenting with thecommands on your own using the Terminal-menu in Datalyse or thewindows-program Terminal. It should be possible to have datacorresponding to a graph send to pc with one single command, butit is not (or I have not figured out how).
As a result it is only possible to transferdata to the pc while measuring them.

It is now possible to use the Terminal menu to receive a scan from Hitachiand afterwards to copy the result from the memo to the table in Datalyse or toExcel.
