A dish sold by weight is priced per unit of weight: a prawn at RM 120.00 the kilo, a salad bar at RM 3.50 the 100 g. Its quantity is a weight, such as 0.455, and the line comes to the weight times the price.

The weight is typed on a number pad, or read off a scale plugged into the POS: an Aclas OS2 scale, by USB, on the Windows and the Android POS alike.

Before you start

  • The dish has Sold by weight / measure ticked in the back office, on its Pricing tab, and a unit such as KG. Its price is the price of one unit. See Items: Pricing.
  • To read a scale, the scale is plugged into this POS by USB and switched on for it: on the POS, ⚙, Hardware, Scale, Read a scale on this POS. See The scale. Without a scale, the weight is typed.
  • Whether the POS asks the weight at once is a setting of the POS, in the back office: Ask the weight when a sold-by-weight item is picked, on the POS terminal setting's Selling tab. See POS Terminal Settings: Selling tab.

Weigh a dish as you pick it

  1. Put the dish on the scale.
  2. Tap the dish's button (or type its code, or pick it in the search list). The weight pad opens.
  3. Watch the scale line under the entry until it says steady.
  4. Press ⚖️ Read scale. The weight fills the entry, for example 0.455. Or type the weight yourself.
  5. Press OK. The dish goes on the bill with that weight.

  2. Sold by weight: read the scale, or type the weight. Cancel does not add it.: on a POS with no scale, Sold by weight: type the weight. Cancel does not add it.
  3. The entry: the weight, up to three decimal places.

Read scale, step by step

When you press ⚖️ Read scale:

  • It says Reading scale…, and the line under the entry says what it is waiting for: Waiting for the weight to settle…, Waiting for the scale to send a weight…, Connecting to the scale…
  • It waits for a steady weight, for about ten seconds at most. It always ends: a scale that sends nothing says so in words.
  • A good weight fills the entry, in the dish's own unit: kilos to three places, grams in whole numbers.
  • If you type while it waits, what you typed is kept, and the pad says The weight arrived after you started typing, so what you typed was kept.
  • A refused weight leaves the entry as it was, and the pad says why. See What if….

Weigh a dish already on the bill

When the POS does not ask the weight at once, the dish goes on at 1. Then:

  1. Tap the line's quantity square. The quantity pad opens, with Now 1. Type the weight. Nought voids it.
  2. Put the dish on the scale, and press ⚖️ Read scale. Or type the weight.
  3. Press OK. The line takes the weight.

The same way changes a weight already on the bill. See Change the quantity.

On the bill

A line sold by weight: the weight, the unit and the price per unit.
  1. 0.455: the weight, in the quantity square. Under the name: the weight with its unit, times the price of one unit, and what the line comes to: 0.455 kg × 120.00 = 54.60.

A dish sold by weight always has a line of its own: a second one is weighed again.

On Android

The scale works the same way, by USB. The differences:

  • ⚖️ Read scale is a green button.
  • After a good read, the line under the entry says what was read: Weighed 0.455 kg.
  • The first time the scale is used, Android asks whether FooodPos may use the USB device. Answer Allow. Until then the line says Scale: waiting for permission.
  • The quantity pad of a line sold by weight says Weighed: type the weight, up to three decimal places.
  • Its own words for what goes wrong are in What if…, marked Android.
