Understanding the Ohaus Triple Beam Balance

The video tutorial, presented by Ibu Prastiwi, explains how to use an Ohaus triple beam balance. It begins with an introduction and objective, followed by a detailed demonstration of adjusting the weights on the balance to measure an object's weight accurately. The tutorial emphasizes ensuring the balance is stable and the pointer is at zero before reading the measurement. The example used in the video results in a weight of 143 grams. The session concludes with a summary and farewell.
