Detailed Description

It is a range of hand held, single and three phase portable working standards, ideal for on site testing. Either direct current connection or current clamp connection is possible. It is a three phase portable standard meter used to verify active and reactive three phase meters (3 or 4 wires) and single phase meters (2 or 3 wires). It is designed to work in the field or in the laboratory 1) U max: 450V 2) I max in direct connection: 20A 3) Connection with current clamps: standard 100A; 200A, 500A and 2,000A current clamps can be delivered as option 4) AC voltage supply switchable between external voltage and test voltage (45V to 285V), DC voltage supply from 4.5V to 5.75V 5) Accuracy in direct connection: a) Active energy: typical: 0,1%, worst case: 0.2%. b) Reactive energy: typical: 0,15%, worst case: 0,3%. 6) Accuracy with current clamps: a) Active energy: typical: 0.2%, worst case: 0,5% b) Reactive energy: typical 0,5%, worst case: 1% 7) Weight: 1.8kg 8) Dimensions: 220 x 140 x 70mm 9) It has a 240x128 LCD screen with lighted background. It incorporates a 19-key keyboard with which it is very easy to access the following main functions a) Measuring mode: gives information about the parameters of the line under test, like phase voltage, phase current, phase and three-phase active power, phase and three-phase reactive power, phase and three-phase apparent power b) Phase and three-phase power factor c) Phase angle between V and I d) Frequency. i) Vector diagram: draws line vector diagram ii) Wave form: shows wave form of current and voltage iii) Meters test: performs test to meters. The data field configurable in this function is the serial number, the meter type (active or reactive), the constant, the divisor factor (for HF), the type of test (automatic/manual) and the number of disks revolutions or pulses of each test iv) It can store up to 224 data groups. Each data group includes voltage, current, power, phase angle and error v) Harmonics: makes a graphic or numeric analysis of THD vi) It has a RS232 interface to communicate with a PC. The data outputs are of three types: screen copy, to print real time test values (voltage, current and power), output of real-time test data which is transmitted out instantly and output of recorded data
