V-2000 Method Update

The V-2000 photometer makes use of internally stored calibration software, which CHEMetrics periodically upgrades. As calibrations are updated or new methods become available, a simple upload procedure allows analysts to upgrade their V-2000 calibrations from their computers. The step-by-step procedure is listed below and in Chapter 5, section 5-3 of the V-2000 Operator’s Manual.

Current Method Version:

The link below will upload the most current method version, Method Revision 18.0, which became available on June 25, 2018. Method Revision 18.0 impacted the products listed below.

Note: Newly purchased V-2000s will not include calibration programs that were removed with new method revisions. However, performing the "Procedure for Method Update" below will not remove these programs.

To determine which method revision is currently present on your V-2000 instrument, simply turn the instrument on. As the instrument powers up, the method revision number is displayed briefly.

Equipment You Will Need to Upgrade your V-2000:

Connecting a computer to the V-2000 requires the use of the RS-232 serial cable supplied with the V-2000. This cable has a special 3-pin connector on one end for the V-2000. The RS-232 port is on the underside of the instrument. When connecting the RS-232 cable to a computer, a serial connector may be required (a 25 pin to 9 pin adapter is included with the V-2000). If your computer does not have a serial port, you will need to purchase a separate adapter that will allow you to connect the V-2000 RS-232 serial cable to the USB port on your computer. Part number for USB to serial adapter: A-0307.

Procedure for Method Revision Update:

It is recommended that you print this page of instructions before continuing.
The step-by-step procedure is also listed in the V-2000 Operator’s Manual, Chapter 5 section 5-3 Uploading Method Revisions. 
NOTE: Uploading a new method revision does not overwrite any user generated custom methods or discontinued methods.
  1. With the V-2000 power off, connect the V-2000 to a computer using the supplied RS-232 serial cable.
  2. Press the power key to turn the V-2000 on.
  3. Press the setup key and use the “up” or “down” keys until “UPLOAD” is displayed, then press the yes key. V-2000 should display “WAITING”. 
    NOTE: To abort the upload process, press the yes key again.
  4. Initiate the download program: Click here to Download the Latest Version and follow the instructions provided in the file.
When the program is complete, the V-2000 will briefly display “ALL DONE” along with the new method revision number.
