The least count of the balance has been given in the balance itself.Otherwise place the weight in the balnce and check the result in the balance.If the result shows for 1kg i.e 1.001 then the lease count of the balance is 0.001kg.

digital micrometer least count calculation
0.1g
least count of a spectrometer is equal to 1' (one minute)
The least count of the micrometer screw can be calculated using the formula given below: Least count = 0.01 mm
0.1 degree

the least count of the device must be noted first. the uncertainty of this will be the least count divided by 2. so if its is 0.1 then it will be 0.05
Least count is the smallest measurement that could be done by the instrument. In ordinary scale we have every cm gap seems divided into ten equal parts. Hence the least count will be 1/10 of cm. Same way in the spring balance the markings might have been made in different ways. Suppose if 100 g marked gap is divided into 5 equal parts then the least count woud be 100/5 = 20 g. If suppose 50 g marked gap is divided into 4 equal parts, then the least count becomes 12.5 g. So it depends on the calibration of the scale.
Its least count is 0.001g i.e minimum among other balances.Its precision is maximum due to minimum least count.So electronic balance is an accurate balance.
