美国ACL-900静电椅测试仪 的详细介绍 ：型号：ACL-900；产地：美国；尺寸：大约W95*L190*H50mm；毛重：4磅；电源：9V电池；测试范围：10的3次方至10的12次方Ω；测试电压：自动调节10V传导/100V耗电；精确度：±10%。 Chair Check calibration procedure.
This product has been produced using 1 % metal film resistors, and high speed OP-AMP Integrated circuits. The calibration procedure is based upon the product being of linear technology.
Its changeover points are determined on resistance and are + or - 1/2 decade on a logarithmic scale i.e. (3.16 x 10n). The linearity of the changeover points are + or - 10% from the mean value per unit.
The resistance decade box required will need a range of from > 1kilohm up to 999 meg ohms 10/9 or higher if
possible. If the resistance decade box only has the ability of checking up to 10/9, measurements greater than
10/9 are calculated using cad generated techniques. Connect the test leads from the resistance decade box
to the red and green banana sockets on the meter. Set the decade box to the desired resistance i.e. 10/3 = 1k,
then press and hold the checker’ test button, the green conductive LED should light, and the analogue needle
should move from left to right indicating 10/3. 10k = 10/4 and so on. N.B. Please note that the checker can be
adjusted via the potentiometer just below the analogue display, if readings are constantly high or low
throughout it’s range.
ACL is pleased to announce the addition of another new product. The ACL 900 Chair Tester is designed to check
all of the elements of the seat, back, and arms of chairs in ESD environments.
The chair is easy to use with an easy to read display. Dual measurements LEDs offer a reliable chair
measurement in seconds. More importantly, this chair measures resistance to ground.
The ACL 900 comes complete with a stainless steel chair castor plate, an insulating plate, connecting leads and
a unique analog meter incorporating quick reference color-coded LEDs to indicate the conductive, dissipative, and insulative conditions of the chair.
