INSTALLATION & SETUP Choose a location that is free from the influences of the following: Drafts: Fans, Heat/Air Duct, Doorways or High Traffic Areas. Vibrations. Extreme Temperature Fluctuations: Sunlight, Ovens, or Environments with Wide Temperature Variations. Voltage Fluctuations. Do Not Share Current with Other Instruments that Draw Voltage in an Inconsistent Manner such as Fluorescent Lights, Centrifuges and the like.
AC POWER CONNECTION - When connecting power use the original AC adapter supplied with the balance. Using an unapproved power supply may damage the instrument and void the warranty. - Ensure the power supply is compatible with your instrument AND the local line voltage. - Connect the plug to the instrument.
CALIBRATION Calibration is required at installation (see Installation & Set-up) and at regular intervals thereafter. Calibrate if the balance is moved to a new location. 1. Allow a 60-minute warm-up period. 2. Press Tare to zero the balance (0.0000g) – if required. 3.
Good Weighing Technique Working with precision balances requires a steady hand and an even, uninterrupted technique. Use forceps or other suitable utensils to place the sample (and sample container) on the weigh pan as fingers are hygroscopic. If the balance has been idle and the draft chamber doors closed for an extended period, perform a number of test measurements before you begin weighing to allow the atmospheric conditions (temperature, RH and barometric pressure) inside the weighing chamber to adjust to the ambient temperature outside the chamber.
