This manual should be easily accessible to the operator at all times during instrument operation. When not using the instrument, keep this manual in a safe place. If this instruction manual becomes lost, order a replacement from your local JASCO distributor. Note: The operating procedure varies with the type of instrument.
Ensure that the instrument is grounded. Operate the instrument in a temperature range of 15 to 30 °C. Operate the instrument in humidity below 85% (RH). JASCO recommends operating the instrument in humidity below 60% to avoid the deterioration of the optical components due to the condensation caused by high humidity.
Consumable parts should be ordered according to part number from your local JASCO distributor. If a part number is unknown, give your JASCO distributor the model name and serial number of your instrument.
Limited Warranty Products sold by JASCO, unless otherwise specified, are warranted for a period of one year from the date of shipment to be free of defects in materials and workmanship. If any defects in the product are found during this warranty period, JASCO will repair or replace the defective part(s) or product free of charge.
