Operating instructions METTLER TOLEDO MT/UMT balances 1 Your balance is distinguished primarily, however, by its user friendliness: You attach the weighing cell to the evaluation unit, connect the balance to the power supply and after 60 minutes warm-up time (with an acclimatized balance) you can immediately start weighing. You thus obtain your first weighing result in an extremely short time. Your balance smooths the way 1.
2 1.2 Preparing your balance If you fold out the front fold-out, you have in front of you an immediate overview of all general illustrations at a glance. You need undertake the following operations only on first-time installation and each time you change the balance location. - No direct sunlight - No extreme temperature fluctuations - No extreme fluctuations in the atmospheric humidity - No excessive drafts (e.g.
Operating instructions METTLER TOLEDO MT/UMT balances Unpack your balance Connect the evaluation unit and the weighing cell - Plug the supplied connection cable into connection socket 7 of the evaluation unit (marked with “For connection to weighing cell only”) and plug the other end into connection socket 19 of the weighing cell (marked with “For connection to evaluation unit only”). It is immaterial which end of the cable you connect to the evaluation unit or the weighing cell.
4 Mount the weighing pan and the draft shield Level your balance - - - The MT balances are supplied with mounted weighing pan. You thus only need to mount the glass cover on draft shield 12 of the weighing cell. The UMT balances have a smaller weighing pan than the MT balances (to avoid cornerload errors). The weighing pan is already mounted, on delivery. You thus need only mount the glass cover on the draft shield 12 of the weighing cell.
Operating instructions METTLER TOLEDO MT/UMT balances STANDBY After connection, your balance is on standby. If your balance is already acclimatized (depending on the temperature difference between the old and new location, this takes 6 to 12 hours), it provides you with the first reliable results after 60 minutes warmup time. After approximately 2 hours you can count on very accurate weighing results. 1.
6 Your balance is fitted with a fully automatic door function, which ensures that the draft shield is always open or closed at the right time. Section 3.4 describes how you can switch off this automatic mechanism. On completion of the self-test, this function opens the draft shield completely automatically. ------ 0.000 mg Zeroing of the display (taring) is automatic.
