Zubr V1 - Digital Voltmeter Manual

Purpose

Please read this document thoroughly before installing and using the digital voltmeter. This will help to avert possible danger, mistakes and misunderstandings.
The digital voltmeter V1 is designed to monitor the voltage of a single-phase circuit, as well as to store the maximum and minimum operating voltage in the non-volatile memory.

ATTENTION! It is prohibited to operate V1 from sources with a modified sine wave or uninterruptible power supplies with the output voltage other than a sine wave. Long-term operation (more than 5 minutes) from such voltage sources can damage the voltmeter and entail non-warranty repair.

Technical data

Supply package

Connection scheme

Voltage for measurement and supply (100-420 V, 50 Hz) is applied to terminals 1 and 2.

The simplified internal circuit and connection scheme

Installation

The appliance is intended for installation inside residences. The risk of moisture or humidity in the installation site should be minimal. When installing in the bathroom, toilet, kitchen, pool appliance must be located in a shell with protection degree not below IP55 per GOST 14254 (partial protection from dust and waterproof in any direction).
The ambient temperature during installation should be within –5...+45 °С.

The appliance is installed in a special box, which allows to conduct the easy installation and operation.
Cabinet should be equipped with standard mounting rail 35 mm width (DIN rail). The appliance takes in width of three standard modules on 18 mm.

The height of the appliance should be in the range 0,5...1,7 m from the floor.
To connect your device:

• fix the appliance on the mounting rail (DIN);
• take a wire;
• make the connection according to the passport.

Terminals of the device designed for wire cross section up to 16 mm2. To reduce mechanical load on the terminals it is desirable to use soft wire. Clean the end wires of 10 ±0,5 mm. If end is longer, it can cause a short circuit, and if short — cause unreliable connection. Use the cable lugs. Undo the screws of the terminals and insert tipped end of the wire in terminal. Tighten terminal with derived average 2,4 Н·m. Low tight may lead to low contact and overheating terminals and wires and over tight — damage terminals and wires. Wires protracted in terminals with a screwdriver with a shank width not more than 6 mm. Screw with shank width more than 6 mm may apply mechanical damage to terminals. This could result in loss of warranty.

Exploitation

Enabling

When turned on, the voltmeter immediately begins to measure and display the value of the mains voltage.

Maximum voltage

To view the maximum voltage, press the top button. The stored maximum voltage will be displayed on the screen with a dot in the rightmost digit.
Five seconds after the last pressing of the buttons, the voltmeter will return to displaying the mains voltage.

Minimum voltage

To view the minimum voltage, press the top button. The stored minimum voltage will be displayed on the screen with a dot in the rightmost digit.
Five seconds after the last pressing of the buttons, the voltmeter will return to displaying the mains voltage.

Resetting the stored maximum and minimum voltage

A short press on the middle button will display «rSt» on the screen.
When the button is released, the voltmeter will erase all stored voltage values from memory. Three seconds after the last pressing of the buttons, the voltmeter will return to displaying the mains voltage.

Correction of indications on the screen (recalibration)

If you think that the readings of the voltmeter V1 and your reference device differ, the readings can be calibrated.
To do this, enter the correction menu by holding down the middle button for 6 seconds until «Cor» appears on the screen. After releasing the button, you will see a blinking correction value, which can be changed with the Max button to increase or Min to decrease the value.

The range of variation corresponds to ±20 V. Five seconds after the last pressing, the voltmeter will return to displaying the mains voltage with the adjustment made.

View firmware version

To view the firmware version, hold the middle button for 12 seconds.

POSSIBLE PROBLEMS, CAUSES AND WAYS TO OVERCOME THEM

When turned on the screen does not light up

Possible cause: No supply voltage at terminals 1 and 2.
It is necessary to: Ensure supply voltage presence.
