Overvoltage/Installation Category

DMMs are categorized depending on the risk and severity of transient overvoltage that might occur at the point of the test. Transients are short- lived bursts of energy induced in a system, e.g. caused by a lightning strike on a power line.

The existing categories according to EN 61010-1 are:

CAT I| A CAT I-rated meter is suitable for measurements on protected electronic circuits that are not directly connected to mains power,

e.g. electronics circuits, control signals…

---|---

CAT II

| A CAT II-rated meter is suitable for measurements in CAT I- environments and mono-phase appliances that are connected to the mains using a plug and circuits in a normal domestic environment, provided that the circuit is at least 10 m apart from a CAT III- or 20 m apart from a CAT IV-environment. E.g. household appliances, portable tools…

CAT III

| A CAT III-rated meter is suitable for measurements in CAT I- and CAT II environments, as well as for measurements on (fixed) mono- or poly-phased appliances that are at least 10 m apart from a CAT IV environment, and for measurements in or on distribution level equipment (fuse boxes, lighting circuits, electric ovens).

CAT IV

| A CAT IV-rated meter is suitable for measuring in CAT I-, CAT II- and CAT III environments as well as on the primary supply level. Note that for all measurements on equipment for which the supply cables run outdoors (either overhead or underground) a CAT IV meter must be used.

Warning:
This device was designed under EN 61010-1 installation category CAT III 600 V. This implies that certain restrictions in use apply that are related to voltages and voltage peaks which can occur within the environment of use. Refer to the table above.

• This device is only suitable for measurements up to 600 V in CAT III.

Pollution Degree

IEC 61010-1 specifies different types of pollution environments, for which different protective measures are necessary to ensure safety. Harsher environments require more protection, and the protection against the pollution that is to be found in a certain environment depends mainly on the insulation and the enclosure properties. The pollution degree rating of the DVM indicates in which environment the device may be used.

Pollution degree 1| No pollution or only dry, nonconductive pollution occurs. Pollution has no influence. (only to be found in hermetically sealed enclosures)
---|---
Pollution degree 2| Only nonconductive pollution occurs. Occasionally, temporary conductivity caused by condensation is to be expected. (home and office environments fall under this category)
---|---
Pollution degree 3| Conductive pollution occurs, or dry non-conductive pollution occurs that becomes conductive due to condensation which is to be expected.

(industrial environments and environments exposed to outside air – but not in contact with precipitation)

Pollution degree 4| The pollution generates persistent conductivity caused by conductive dust or by rain or snow. (exposed outdoor environments and environments where high humidity levels or high concentrations of fine particles occur)

Warning:
This device was designed by EN 61010-1 pollution degree 2. This implies that certain restrictions in use apply that are related to pollution which can occur within the environment of use. Refer to the table above.

This device is only suitable for measurements in Pollution degree class 2 environments.

Operation

DC + AC VOLTAGE MEASUREMENT

****| Do not measure circuits that may contain voltages > 600 VDC or

600 VAC

---|---
****| Use extreme caution when measuring voltages higher than 60 VDC or 30 VAC rms.

Always place your fingers behind the protective edges of the test probes while measuring!

1. Insert the red test lead into the “VΩmA” jack and insert the black test lead into the “COM” jack.
2. Set the rotary switch to the voltage range and touch the test lead probe tips to the circuit under test, the red test lead connection will be displayed.

Notes

• Set the rotary switch to a higher range if not know the current range under test, and then lower it down till the best accuracy.
• To avoid electrical shock and/or damage to the instrument, do not attempt to take any voltage measurement that might exceed 600VRMS.
• It is a normal situation and does not affect the measurement, once at 200mV or 2V range, even without input or connection with the test lead, the meter shows value in LCD.
• An over-range is indicated by OL or -OL. Set to a higher range.
• The maximum input current is 600 V rms.

DC CURRENT MEASUREMENT

****| Do not measure circuits that may contain voltages > 600 VDC or

600 VAC

---|---
****| Use extreme caution when measuring voltages higher than 60 VDC or 30 VAC rms.

Always place your fingers behind the protective edges of the test probes while measuring!

1. Insert black test lead into COM jack, for current measurement less than 200mA insert the red test lead into “VΩmA” jack, for current measurement between 200mA to 10A insert the red test lead into 10A jack.
2. Set the rotary switch to the current range and touch the test lead probe tips to the circuit under test, the red test lead connection will be displayed.

Notes

• Set the rotary switch to a higher range if not known the current range under test, and then lower down untill the best accuracy.
• If display“OL” for over range, set the rotary switch to a higher range.
• Indicates the max current is 200mA or 10A based on jacks the red test leads to be inserted, the fuse will be blown out at over-range current.

RESISTANCE MEASUREMENT

Do not conduct resistance measurements on live circuits. Make sure all capacitors in the circuit are depleted.

1. Insert the black test lead into the “COM” jack, and the red test lead into the “VΩmA” jack.
2. The rotary switch to Ω range and touch the test lead to under-tested resistance and read the value from LCD.

Notes

• If display “OL” for over range, set the rotary switch to a higher range. For measuring over 1MΩ high resistance, the meter may take a few seconds to stabilize the readings.
• In the open circuit, the meter displays “OL” to indicate no input.
• To avoid electric shock, disconnect the power to the unit under test and discharge all capacitors before taking any resistance measurements.

DIODE AND CONTINUITY TEST
Do not conduct diode or continuity measurements on live circuits. Make sure all capacitors in the circuit are depleted.

1. Insert the black test lead into the “COM” jack and the red test lead into the “VΩmA” jack, the polarity of the red test lead is “+”.
2. Set the rotary switch to the range, and place the red test lead on the anode of the diode and the black test lead on the cathode of the diode, the meter will show the approx. forward voltage of the diode.

CONTINUITY CHECK

1. Insert the black test lead into the “COM” jack and the red test lead into the “VΩmA” jack.
2. Set the rotary switch to range and touch the test leads to both points of the circuit, if the resistance between two points is less than 50Ω±30Ω, the inbuilt buzzer will be sounded

NOTES

1. Even without buzzer sounds, voltage may still exist. Do not rely solely on non-contact voltage detection to determine the presence of voltage. Detection operation may be subject to socket design, insulation thickness different types and other factors.
2. When the meter input terminals detect voltage, due to the influence of the present voltage, the voltage sensing indicator may also light.
3. Keep the appliance away from electrical noise sources during tests, i.e. fluorescent and dimmable lights, motors, etc. These sources may trigger NCV detection and invalidate the test.

DATA HOLD
In any range, short press /H to lock the display value. The H sign will appear on the display. Short press /H again to exit.
