日本岩通计测iwatsu 全新6位半数字万用表 voac7602. 产品简介：日本iwatsu 岩崎公司在东京正式发布公司革新技术的新产品6位半台式万用表 voac7602 ，及香港地区的销售及市场支持授权总代理捷创力高仪器有限公司全权受理，即日起正式对市场同步出售。 产品特点及详细参数： to use the functions described below, you need to update your firmware for voac7602 to the latest version. "bulk mode" 30ks/s (new) the measurement in the bulk stops the other functions than measurement data acquisition when measurement is done. therefore, logging can be done while ensuring the sampling rate of up to 30ks/s. the measured data is kept in log memory, and trend chart and histogram chart can be displayed by offline browse function. the data can be stored in a memory as well. pre-trigger function utilizing log memory effectively (new) voac 7602's bulk mode can stop loading levels of measurement values, limit judgment result, external trigger, etc. , by setting "stop event". this triggering can be used in similar way to oscilloscopes' pre-trigger function. you can focus on data taken around when the event occurred. in addition, as log memory has 100k readings, a long time data can be loaded with high resolution at high speed sampling. moreover, as this multimeter can accept "stop event" just after start of the logging, you do not need to wait for the time which inhibits the trigger even if sampling rate is low. so, the loading time will be minimized. a long time logging is available with long time memory. voac7602 has a large memory, which can store the log for up to 100k points. example: logging more than one day is available when sampling rate is 1 time/sec. sampling rate ( samples/s) 1 4 20 100 500 1k 2k 7.5k 15k 30k loading time ( h : m : s) 27:46:40 6:56:40 1:23:20 0:16:40 0:03:20 0:01:40 0:00:50 0:00:13 0:00:07 0:00:03 offline/histogram chart display, being useful for yield ratio measurement (new) display the data loaded into the log memory in a histogram chart, so that you can measure the yield rate easily by cursor operation. so far this rate was calculated by pc, this will improve your work efficiency at significant level. the limit judgment can be performed on site. the number of times within the ranges specified by cursors, and the ratio will be displayed in percentage figures (%). since indexes suitable for the basis such as voltage can be set as x-axis, you intuitively understand the ratio of acceptance/rejection criterion. offline-trend chart display:temporal alteration of measurement value shown (new) besides the display function such as an oscilloscope’s, the function to recalculate the statistic data within the cursor range will help you get the statistical data for the range you need. as you can save the display data in usb memory, this function will improve working efficiency furthermore. highly-improved limit function （new) voac7602 can perform the advanced analysis based on the result of limit function, and this will be performed by easy operation. this product gives you clear answers to your most difficult questions such as how many troubles happened, when they happened and so on. the right figure gives the answer to: "how many troubles happened" the right figure gives the answer to: "when they happened" easy extraction of necessary parts by offline cursor function (new) various kinds of trigger functions to meet market needs interval trigger function this function repeats measurement at fixed time interval until such measurement is performed certain times specified in advance. trigger delay function this function let you set the delay time from the trigger input to the first data measurement. you can delay the measurement timing of the production facilities and measure the data after the facility become stable.
