## Others

### NCV (Non-contact Voltage)

VEGO has an internal magnetic sensor to detect the electromagnetic field of an AC voltage. In position f or NCV mode, the built-in buzzer will periodically sound while VEGO is in proximity of a AC voltage source (e.g. Line power). The buzzing frequency increases for higher AC voltage.

### Current Measurement

In position g or \[A] mode, the internal fuse can sustain 10A current for 10 seconds. To prevent blowing the fuse, DO NOT exceed 10A while measuring the current.

### Automatic Power Off (APO)

By default setting, VEGO will trigger APO after 15 minutes of inactivity (the built-in buzzer will sound 5 times one minute before shutdown).

To resume the setting from APO, press SEL button so VEGO will resume back.&#x20;

To disable APO, press and hold the SEL button first and then turn ON the device. The buzzer will sound 3 times to indicate the deactivation of APO.

## Safety Instructions

{% hint style="danger" %}
When measuring, **do not** exceed the maximum **measured value** specified in the “Technical Specifications”.
{% endhint %}

{% hint style="warning" %}
Voltage below **36V** is the safe voltage. When the voltage being measured is higher than 36V(DC) or 25V(AC), check whether the test leads are in reliable contact, are connected correctly, and are well insulated to avoid electric shock.
{% endhint %}

{% hint style="info" %}
When changing functions and ranges, the test leads should leave the test point.
{% endhint %}

{% hint style="info" %}
Select the correct function and range, and if there is an over-range,  the display appears “OL”.
{% endhint %}

### Attentions

1. Except for battery and fuse replacement, **DO NOT** attempt to repair the meter or change inner circuit; please contact our technical support directly
2. This product should **NOT** be stored or used under high temperature, high humidity, flammable, explosive and strong magnetic environments
3. Clean the case with a damp cloth and a mild detergent. **DO NOT** use corrosives or solvents&#x20;
4. Turn OFF the meter before cleaning.
5. Remove the battery if you don’t use the device for long time
6. When the display shows<img src="https://lh5.googleusercontent.com/xWrVpBT05E7jIuGc5YF1uZdflhA1pp2TB34KH3H86XDHUSg7EglPmGoxHePRZMGEkh-F1vTJCkHBGNP5h-RvpWefyAnbbcwB5K9lb-U3u6DDtIXP9qsY4oOL2bj8kwSelwMpVL8w2D4FZVh6xUfuLw" alt="Empty battery" data-size="line">symbol, replace the batteries under the following steps:

&#x20;          \- Unscrew the battery lid at the back

&#x20;          \- Remove all batteries inside

&#x20;          \- Replace new batteries of the same type

&#x20;          \- Install the battery lid and fasten the screws

&#x20;          \- Dispose the old batteries to proper recycle centers&#x20;

&#x20;          \- When replacing the fuse, please use the same size and type of fuse

## Common Problem

#### Current Measurement Not Working (Other Functions OK)

**Cause:** This issue is most commonly caused by a blown current-measurement fuse. The fuse is typically blown when the VEGO is connected in current mode directly across a voltage source or into a circuit with little or no resistance, resulting in excessive current.

Here is a step-by-step guide on how to replace the fuse:

1. Using a screwdriver, remove the rear battery compartment cover. Then take out all of the batteries before replacing the fuse.

<figure><img src="https://2395483440-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FFcgTb7Dst30iGr6yQqof%2Fuploads%2F7HRSthZbLY02GEMqukhI%2FIMG_5230.JPG?alt=media&amp;token=c68619e1-5dda-4e3d-89cc-b4b1d241c77e" alt=""><figcaption></figcaption></figure>

2. **Use a screwdriver to gently pry the rubber sleeve away from the meter.** It may require a little force, as the sleeve fits tightly around the device.

<figure><img src="https://2395483440-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FFcgTb7Dst30iGr6yQqof%2Fuploads%2FL4apZQS2o6LkaCuUuOTe%2FIMG_5231.JPG?alt=media&amp;token=5e5ca413-afec-487a-93f4-2d5b6b1a778c" alt=""><figcaption></figcaption></figure>

3. After removing the rubber sleeve, remove the screws and open the back cover.

<figure><img src="https://2395483440-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FFcgTb7Dst30iGr6yQqof%2Fuploads%2Fa8s40GvuYHuZnqcMrX9M%2FIMG_5232.JPG?alt=media&amp;token=0cde7dd3-163e-408a-9033-07bcdce5cde2" alt=""><figcaption></figcaption></figure>

4. After removing the back cover, you will see two glass fuses, one on each side of the PCB. For most users, the fuse that needs replacing is the left-side fuse, which protects the current (mA) input. You can identify it by tracing it to the mA input port on the front of the meter.

   The replacement fuse specification is:

   * 0.5 A
   * 250 V
   * Glass Fuse
   * 3.6 × 10 mm

   Recommended replacement:\
   <https://www.amazon.ca/dp/B0DWRNZQQX?ref=fed_asin_title&th=1>

   Gently pull the blown fuse out of its holder and insert the new fuse. If your replacement fuse has long leads (typically supplied for through-hole PCB mounting), simply trim the excess leads with a pair of wire cutters before installation.

5. After replacing the fuse and reassembling the meter, test the mA measurement function. If the replacement was successful, the meter should display a valid current reading.
