ST-9040K Single Phase Reference Energy Meter

Introduction:

ST-9040K Multifunction Portable Polyphase Measuring Instrument is the latest generation instrument whole computerize, multifunction, high accuracy, easy to use and portable size suitable for worksite or lab. It is a powerful tools for testing energy meter and voltage, current, power, phase meters.

The instrument adopts digital multiple principle and technique. It could measure four quarters and display by large scale LCD with audio visual and easy to use, the voltage measurement with wide range without change the ranges. The current input adopts direct input and clamper input two methods. It is possess of time clock and testing data register and inquiry functions and could communicate and manage data through the computer.

ST-9040K divides into two types: between them ST-9040K could memory 100 sets of meter data and ST-9040KA could memory 1000 sets of meter data every times.

Functions and Features:

It adopts digital multiple technique to adopt sample with three-phase voltage and current simultaneously and high speed calculate and analyze the adopted data. It could calculate each phase voltage, current, power, and energy value with four-quarter measurement without self-cheek.
Menu with push key easy to use.
Large scale LCD display with high light for dynamic display three phase voltage,
current, power, dynamic power factor or vector diagram, phase angle and frequency simultaneously.
Energy measurement: It could receive scanning head and hand operated switch input starting signal to display total energy value in fixed turns.With mutual communication functions eg. It could mutual transferthe data through serie interface between ST-9040K and computer.With quick calculate error function. It could display twice-testing error and average error.

Test: It could receive scanning head and hand operated switch and electronic energy meter input signal and continue display the testing meter relative error.The testing meter constant could in fraction.It could output standard pulse signals with 3 kinds frequency (positive and negative active power, reactive power), FH1=100 kHz, FH2=10 kHz, FL=1Hz (5V square ware), auto display pulse equivalent.
Wire check function: New calculating method can be caused the wire check results (48 kinds) not affecting with the current thus, suitable for worksite.
Phase sequence function: During 3 phase 3 wire phase measuring status could measure voltage positive or negative phase sequence at present.
Data register function: It could memory 100 (1000) sets meters measuring data not onlycould inquire at any time but also transfer to computer for management.
Time function: It could record testing time and could normal operation when switch off the instrument.
Temperature function: Under "reset" mode press "1"key to measure the temperature onetimes at present, press again to measure the temperature again, when press "reset" key then return.Modern injection molding cabinet and electro- conductive rubber key with fine appearance, lightweight and sturdy. The dimensions 360L*257B*120H mm, weight 3 Kg.
