penunjuk pada sifar = pointer at zero Before putting anything on, check that the pointer of the scale is at 0. If it is not, every reading will be too much or too little. A small knob can reset it. Example: the pointer starts at 1 kg and shows 4 kg with the object, so the object is really 4 - 1 = 3 kg. Watch out: clear any clutter off the scale first, or the pointer will not rest at 0.
Langkah 2
Letakkan objek dengan stabil
Letakkan objek di tengah penimbang dan tunggu penunjuk berhenti.
objek di tengah → tunggu
di tengah penimbang = 秤的中间 东西要放在秤盘中间,放稳以后等指针停下来再看。放在边边,秤会歪或东西会掉;指针还在晃时读数也不准。 例子:指针先晃到 6 kg,停下后在 5 kg,晃动时多看了 6 - 5 = 1 kg。 注意:称的时候手不要按着秤,手的力量会让读数变大。
di tengah penimbang = middle of the scale Put the object in the middle of the pan, then wait until the pointer stops before reading. On the edge the scale may tip or the object may fall, and a swinging pointer gives a wrong value. Example: the pointer swings to 6 kg, then settles at 5 kg, so reading too early adds 6 - 5 = 1 kg. Watch out: keep your hands off the scale, because pressing it makes the reading bigger.
Langkah 3
Baca dan rekod
Baca nilai pada senggatan yang ditunjukkan dan tulis bersama g atau kg.
baca dan rekod = 读数并记录 指针停下后,看它指在哪一条刻度上,再把数字和 g 或 kg 一起写下来。秤面印的是什么单位,就写什么单位。 例子:秤面每格 100 g,指针停在第 3 格,读作 100 + 100 + 100 = 300 g。 注意:秤面印 kg 却写成 g,重量就差了一千倍。
baca dan rekod = read and record When the pointer stops, find the mark it points to and write the number together with g or kg. Copy whichever unit is printed on the face of the scale. Example: each gap is 100 g and the pointer is on the third gap, so it reads 100 + 100 + 100 = 300 g. Watch out: writing g when the scale shows kg makes the mass a thousand times too small.

membaca penimbang = reading a scale First check what each small mark is worth (for example 50 g or 100 g), then count from 0 to where the pointer stops. Example: each mark is 100 g and the pointer stops at the 7th mark, so the mass is 700 g. Watch out: always write the unit g or kg.

sebelum menimbang = before weighing The question asks where the pointer should be before anything is placed on the scale. Ask yourself what an empty scale ought to show. Recall the checking step in Langkah 1. Example: an empty bowl shows 2 kg and the bowl with rice shows 7 kg, so the rice is 7 - 2 = 5 kg. Watch out: this is about the moment before weighing, not the reading after the object is on.

bahagian penimbang = part of the scale This question asks where the object should be placed when weighing. Think about which spot keeps it steady so nothing falls and the pointer can stop properly. Look back at the picture in Langkah 2 to check. Example: two 2 kg rice bags resting steadily on the scale read 2 + 2 = 4 kg. Watch out: the word diletakkan means placed, so the question is about position, not about reading.
