The KCS has two models, the KCS-12 or the KCS-60. Both coin scales are identical in size and function, with the only difference being the capacity they can handle. The KCS-12 has a weight capacity of 12lbs and the KCS-60 has a capacity of 60lbs. The KCS Coin Counting Scale is an easy-to-use, highly accurate scale for weighing coins and tokens. The keypad has 10 programmable keys; 6 are preprogrammed for all US coins and 4 extra keys allow for programming tokens. Keyboard unit weight calculations and calibration of all keys are fast and easy. Up to 25 coin counts can be accumulated in memory for batch counting, and can be printed with the optional Printer. During normal use, you run the Scale using the internal, rechargeable battery. The battery provides up to 125 hours of continuous use, so you can go several days between charges. When you are ready, the battery can be recharged with the included AC adapter. Never use the KCS with the adapter plugged in, as it can damage the battery. The KCS comes standard with an RS-232 interface port to attach an optional Printer, sold separately. The Scale will count your coins or tokens in 3 seconds or less, displaying the quantity and total value. The Scale is completely portable and an optional Carrying Case is also available, sold separately. The KCS-60 will weigh a maximum or $1,000 in quarters (4,000 total quarters).
