167. START-UPWhen plugged to mains, the balance displays name and number of software, andafterwards proceeds to weighing mode.7.1 Balance temperature stabilization periodBefore start of measuring processes, it is necessary to wait until the balance isthermally stabilized. It is a period of so called balance self-heating. In case ofbalances PS series self-heating period takes approximately 30 minutes. Thespecified time interval refers to balances that have been stored in room temperaturebefore plugging to mains.For balances that were stored in much lower temperatures before plugging to mains(e.g. during winter period) thermal stabilization should last approximately 4 hours.Correct operation of a balance is possible within temperature range specified in thetechnical parameters, see point 1. If the balance is placed in area which ambienttemperature is out of temperature range specified in the technical data, thenbalance’s display may signal such situation by lighting an appropriate marker (ablack triangle).In case the balance displays the marker, increase or decrease ambienttemperature, depending on present temperature value. It is recommended thatambient temperature changes at balance’s place of use are very small (slow).
