PURPOSE OF THE VOLTAMMETER
 Digital industrial voltammeter VAR-M02 is designed for technological control voltage value and current in electrical circuits of alternating current, as in the industrial areas, and the housing sector, household sector, other objects of the national economy. It can be used as part of automated control systems and process control as the main or additional display on mobile and stationary objects. It is a mean of control. Periodic calibration is not subject.
           
Example of application VAR-M02: - "Came out of the situation like this, drilled a hole in Schneider plugs, the place certainly ate a bit."
 
DESIGN OF THE VOLTAMMETER
 Voltmeter is produced in a plastic case with a unified front connection wires power and switched circuits. Mounting is carried out on a DIN rail  width 35mm (GOST R IEC 60715-2003) or on a smooth surface. To set on a smooth surface, you need to push locks. Terminal design provides robust clamp wires up to 2,5mm2. On the front panel there are digital indicators, showing the value of the voltage and current, button. LEDs have high brightness of a luminescence, providing a reading of information in any light conditions.
 
OPERATION OF THE VOLTAMMETER
 Voltammeter does not require auxiliary power supply, and connects directly to the circuit (terminals A1 and A2).
 The current is measured by contact and non-contact methods. A contactless method by means of internal or external current transformer.
 To measure the current in the range from 0 to 1A, it is necessary a chain with the measured current connect to terminal E and to terminal E2. For matching  indications of the ammeter it is necessary by using a button set the scale of 1A.
 To measure the current in the range from 0 to 5A, it is necessary a chain with the measured current connect to terminal E and to terminal E1. For matching  indications of the ammeter it is necessary by using a button set the scale of 5A (installed by default).
 To measure the current in the range from 0 to 30A, it is necessary a chain with the measured current pass through a hole in the case. For matching  indications of the ammeter it is necessary by using a button set the scale of 30A.
 To measure the current in the range from 0 to 1000A, it is necessary to use an external current transformer, contacts of current transformer connect to terminals E and E1. For matching used current transformer and ammeter indications, it is necessary by using a button set the necessary transformation ratio.
 When non-contact measurement of the current, a conductor with the measured current is passed through the hole in the case. Circuits connection are shown at the picture below and at the case of the device.
 The use of the button to view additional information:
 1st press - Umax since the last reset
 2nd press - Umin since the last reset
 3rd press - the amount of the mains voltage connections since the last reset
 Retention the button for 5 seconds - reset.
