電子天びん、および電子天びんの除電方法

Japanese Patent JP7101239

B2

Provided are a static eliminator capable of performing quick static elimination while having a good ion balance, an electronic balance including the static eliminator, and a static eliminating method of the static eliminator. By this static eliminating method, the ion balance can be regulated in a short time. Further, an electronic balance including the static eliminator inside a windshield is provided. A static eliminator (6) is provided which is configured to eliminate static from a static eliminating object by ions generated by applying high voltages to static eliminating needles (8A and 8B), and has a high-speed static eliminating mode (M1) configured to eliminate static from a static eliminating object at a high speed, and a relaxation static eliminating mode (M2) to be executed by a voltage application method different from that of the high-speed static eliminating mode (M1) and configured to regulate ion balances of the static eliminating object and the area around of the static eliminating object. With this configuration, a static eliminator capable of quickly eliminating static from a specimen while having a good ion balance can be provided. An electronic balance (1) including the static eliminator (6) executes the high-speed static eliminating mode (M1) by a pulsed DC method using a period (T) determined according to a distance corresponding to a distance from the static eliminator (6) to a weighing pan (2) .
