Select to count Euros or Sterling via a single front panel push button. Once the selection is made there are an additional eight dedicated buttons for selection of the coin denomination - 1c, 2c, 5c, 10c, 20c 1 and 2 Euro or 1p, 2p, 5p, 10p, 20p, 50p, £1 and £2. For multiple counts of the same coin denomination, the E520 retains the selected coin type and value until another selection is made. This feature speeds up counting by allowing the operator to simply load the scale. The single channel accumulator allows the value of coin being counted to be added up and totalled without the need for a piece of paper or a calculator. The E520 gives a running total of number of transactions and value after each entry to the accumulator. A push button tare allows the weight of any coin scoop to be taken out of the weighing process, to ensure that accuracy of the coin count. There is also a Big Bag mode which enables the operator to quickly check the contents of bags of coins issued from the bank. The pre-programming for this mode includes both the weight of the individual coinage and the total weight of any packaging, plastic bags, coin wraps etc., so that the user can be sure that a sealed Big Bag has the correct contents without the need to open it. The E520 can be mains powered, or for total portability, powered from six dry cell batteries. Good quality alkaline batteries will give up to 800 hours usage.
