Frequently Asked Questions - MX 604 METRIX

How to test a surge arrester with the MX 604?

Set the switch to the surge arrester test position. For a removed surge arrester, insert it into the support module and press the module's push button. For an in-situ test, connect the ground cord and probe, place the tips on the surge arrester terminals, then press the probe's push button. Read the voltage on the 600 V scale.

How to measure insulation resistance?

Select the desired range (20 MΩ/50 V, 200 MΩ/100 V or 2000 MΩ/500 V) with the switch. Ensure the circuit is de-energized (mains indicator off). Connect the leads, then press the probe's push button. Read the value on the corresponding logarithmic scale.

How to check the battery status?

Set the switch to the TEST position. Press the probe's push button. If the needle is in the black zone, the batteries are charged; in the red zone, they are discharged and must be replaced.

How to replace the batteries?

Disconnect all leads and set the switch to OFF. Remove the 4 screws on the back, take off the bottom case, replace the 3 LR03 batteries respecting polarity, then close.

What safety precautions should be taken?

Never use the surge arrester support clamp on live circuits. Do not exceed the protection limit values. Disconnect the device before any opening. Some internal capacitors may retain a dangerous potential even when de-energized. Only use leads compliant with standard NF EN 61010-2-031.

What to do if the device does not work correctly?

First check the battery status. If the problem persists, take the device out of service and contact qualified personnel for repair. Do not attempt to repair it yourself.

How to clean the device?

Use a cloth lightly dampened with soapy water. Allow to dry completely before use. Never use abrasive products or solvents.

What accessories are supplied with the MX 604?

2. INSTRUMENT DESCRIPTION

This surge arrester tester, associated with a megohmmeter, is designed to provide you with a strong guarantee of safety, maximum protection and unequalled performance. It allows the insulating resistance measurement of earth circuits.

It is a portable, professional, standalone measuring instrument for use by electricians, in order to measure the following magnitudes :

surge arrester voltage
insulating resistance up to 2000 MΩ under 500 VDC
insulating resistance up to 200 MΩ under 100 V DC
insulating resistance up to 20M under 50 VDC

These magnitudes can be accessed using a rotary switch.

2.1. Power supply

The discharger tester is powered by three standard 1.5 V batteries (type LR03) that provide an endurance of about 1500 measures of five sec.

2.1.1. Self-checking of batteries : TEST

Before carrying out a measurement campaign, it is important to check that the instrument power supply batteries are in good condition.

The TEST position of the rotary switch indicates the state of the batteries (it is necessary to press the probe push button).

On the scale, there is an area with two different colours :
- if the needle is positioned in the black area, batteries are charged,
- if the needle is positioned in the red area, batteries are discharged. They must then be replaced.

2.1.2. Replacing the batteries

Unplug measurement circuit test cables, put the rotary switch to the OFF position and remove test cables and the discharger support unit from the instrument.

Proceed as follows to replace the discharger tester batteries :

1. Remove the four screws from the back of the instrument.
2. Remove the lower box.
3. Replace the batteries, taking care that they are in the right direction.
4. Close the instrument.

2.2. Scale

The measurement readout is of the analog type. The discharger tester is fitted with a graduated scale and a needle.

The scale is graduated to give a direct reading without any multiplication factor (logarithmic graduation). The scale length is 79mm (circular arc according to IEC standard 51):

discharger tester scale graduated from 0 V to 600 VDC (black scale)
-logarithmic scale for the 2000M 500V range (blue scale)
-logarithmic scale for the 200M 100 V range (blue scale)
-logarithmic scale for the 20M 50V range (blue scale)
- TEST scale containing 2 colors (white and red scale)

2.3. Input terminals

Measurements are performed :

• either with a specific probe (equipped with a push button) connected to the input terminals through a grey cable and a tripod connector, together with a black lead with a probe tip or an alligator clip
• or with a discharger support unit equipped with 4 male plugs to be connected to the 4 input terminals of the instrument box.

2.3.1. Discharger support unit

This unit is a moulded box with 4 male plugs to be connected to the discharger tester.

On the front face of the unit is to be found :

• 2 recesses to accommodate two different discharger types
• a sliding switch used to select one of the two arresters (twin type) when the test is carried out,
• a push button to launch the measurement.

2.3.2. Probe

The probe allows measurement to be triggered directly from the probe tips by means of a push button. The probe comprises three parts:

1. a probe tip with :

2. a test probe of 4mm diameter and 18mm length

3. a push button for initiating external surge arrester tests or insulating resistance tests

4. a cable with 3 wires (0.5 mm each) of 1.5 mm length

5. a tripod plug which is connected to the measurement instrument.

This plug is fitted with a failsafe device to prevent connection errors.

3. FUNCTIONAL DESCRIPTION

3.1. Discharger test

Switch the commutator to the position

Surge arrester tests can be conducted in two different ways:

a) Table measurement

The instrument is equipped with a surge arrester support unit. The arrester to be tested is then inserted into the appropriate recess. Press the push button to initiate measurement.

b) Onsite measurement

Connect the earth lead and the probe with the tripod plug to the instrument. Place the two ends of the probe tips of the leads on the surge arrester to be tested. Activate the probe push button to initiate measurement. The surge arrester support clamp can be used for this type of measurement.

Read the voltage value on the 600 V scale :

Accuracy : class 10 (10 % of scale range according to ref. conditions)
- Open-circuit output voltage < 950 V DC
- Short-circuit current < 400 A

The surge arrester support clamp and the surge arrester support unit must not be connected to live circuits.

3.2. Insulating resistance measurement at 50V / 20M or 100V / 200M or 500V / 2000M

High voltage is generated at the terminals of the resistor to be measured. The voltage drop measured at the terminals of a known internal resistor in series with the resistor to be measured is used to deduce the value of the resistor.

Tests should only be carried out on circuits out of voltage (the mains light on the instrument scale must be off after disconnecting the test leads and before pressing the probe push button).

Connect the circuit to be measured to the instrument terminals, before starting the measurement.

Measurement results may be distorted by the impedances of additional circuits connected in parallel or by transient currents.

Measurement range: 100 kΩ to 20 MΩ at 50 V 500 kΩ acc. IEC 61557-2, 100 kΩ to 200 MΩ at 100 V with BAT test in the black area 5 MΩ to 2000 MΩ at 500 V

When the circuit is open (infinite Rx), the needle comes to a stop on the right.

The measured value is read off three specific logarithmic scales: 2000 MΩ / 500 V, 200 MΩ / 100 V and 20 MΩ / 50 V, each covering 3 decades.

Measurement current: ≥ 1mA for R = 500k

≤ 4 mA in short-circuit

Protection of inputs: up to 600 V rms

No load voltages: < 75 V dc on the 50 V range

< 150 V dc on the 100 V range

< 750 V dc on the 500 V range

Accuracy : class 10 (10% of scale range according to ref. conditions)
