Frequently Asked Questions - ERT 10 PCE Instruments

What is the overvoltage category of the PCE-ERT 10?

The PCE-ERT 10 is rated for CAT III 1000V, suitable for measurements in distribution circuits.

How do I measure earth resistance?

Connect the green, yellow, and red test leads to terminals E, P, and C respectively. Place auxiliary electrodes in a straight line with the electrode under test. Set the range, press TEST, and read the value.

Can I measure voltage with this device?

Yes, it measures DC voltage up to 1000V and AC voltage up to 750V (40-400 Hz). Select the appropriate function with the measuring function selector.

What should I do if the battery indicator appears?

A low battery can cause incorrect measurements. Replace all six AA batteries immediately. Remove test leads before opening the battery compartment.

- Do not use the instrument in explosive atmospheres.

- The measurement range as stated in the specifications must not be exceeded under any circumstances.

- If the battery is flat (e.g. indicated by the battery indicator), the meter must no longer be used as incorrect measured values can cause life-threatening situations. When full batteries are used again, the measuring operation may be continued.

- Before each use, check the meter by measuring a known quantity.

- This meter is suitable for measurements in circuits with an overvoltage category CAT III up to a voltage of 1000 V.

- To ensure safe operation before starting the measurement, always check whether the correct measurement range is selected and whether the test leads are plugged into the sockets intended for the respective measurement.

- Measurements of resistance, capacitance and temperature as well as diode tests may only be carried out in voltage-free state.

- The bare measuring tips must never be touched because there is a risk of electric shock.

- Be extra careful when measuring high voltages.

- Before opening the housing to replace the battery or fuse, remove all test leads, otherwise there is a risk of electric shock.

- If you do not want the meter to be used for a long time, remove the batteries to avoid damage caused by battery leakage.

- Non-observance of the safety notes can cause damage to the device and injuries to the user.

We do not assume liability for printing errors or any other mistakes in this manual.

We expressly point to our general guarantee terms which can be found in our general terms of business.

5 Operating instructions

Measurement of the effective resistance of earth electrodes

Warning: Before you start the measurement, read the safety instructions above.

Note: Low batteries can falsify the measurement results. Therefore, pay attention to the battery level and replace the batteries before starting the measurement if necessary.

1. Short-circuit the test leads and press the "TEST" key. Use the zero adjustment wheel to set the value to 0 Ω.

2. Move the measuring function selector to the "EARTH VOLTAGE" position and press the "TEST" key. The ground voltage is shown on the display. If the voltage is more than 10 V, this can lead to an incorrect measurement of the earth resistance.

3. To make a precise measurement of the earth resistance:

(1) Connect the green, yellow and red test leads to the device connections E, P and C.
(2) Connect the crocodile clips of the test leads to the earth electrodes (according to the figure below). The auxiliary electrodes attached to P and C must form a straight line with the electrode to be tested (attached to E).
(3) Set the measuring function selector to a suitable measurement range, press the "TEST" key and read the measured value.

1. To use a simplified measurement procedure, proceed as follows:

(1) This method is recommended where the earth resistance is higher than 10 and where it is not possible to drive auxiliary electrodes into the ground. An approximate value can be determined by the two-wire system which can be seen in the figure below.

(2) Move the measuring function selector to the "EARTH VOLTAGE" position and press the "TEST" key. Make sure that the ground voltage is below 10 V.

(3) First, move the measuring function selector to the measurement range 200 Ω, press the "TEST" key and read the measured value. If the display shows "1" (measurement range exceeded), switch to the range 2000 Ω and read the value.

(4) The read value (Re) is an approximate earth resistance value. In this measurement, the test leads P and C do not have to be shot-circuited before the start of the measurement as the special included test lead is used. Tis test lead already has a connection between the two sockets (red test line, see figure).

(5) Actual grounding resistance = read value - earth resistance of earth electrode RX = Re - re

DC/AC voltage measurement

1. Set the measuring function selector to DC/AC (1000 V DC or 750 V AC).
2. Plug the black test lead into the negative COM port.
3. Plug the red test lead into the positive port V.
4. Contact the tip of the black test lead with the negative side of the circuit.
5. Contact the tip of the red test lead with the positive side of the circuit.
6. Read the voltage value in the display.

Note: If the polarity is reversed, there is a minus sign in front of the measured value.

Resistance measurement

Warning: To avoid electric shock, check that the circuit or electrical component is voltage-free before starting the measurement.

1. Set the measuring function selector to 200 kΩ.
2. Plug the black test lead into the negative COM port.
3. Plug the red test lead into the positive port .
4. Contact the tips of the test leads with the component/circuit to be tested.
5. Read the resistance value in the display.

„HOLD“ function

The "HOLD" function "freezes" the measured value on the display. Press the "HOLD" key at the desired moment to capture a displayed reading. Pressing again terminates the function.

Backlight

Press to enable the display backlight. The backlight will switch off automatically after 15 seconds.

6 Maintenance and cleaning

6.1 Battery replacement

A low battery level is indicated by the icon in the display.

Warning: Before opening the earth resistance tester, disconnect it from the measuring circuit, remove the test leads from the meter and carefully remove the fold-down device stand.

To insert the batteries when restarting or to replace the batteries with insufficient voltage, loosen the four screws of the battery compartment cover on the back of the device, remove the lid, insert the batteries or remove the old batteries, replace them with new ones, insert the lid and screw it back in.

6.2 Cleaning

Clean the device with a dry cloth. Do not use any abrasives or solvents.

7 Contact

If you have any questions, suggestions or technical problems, please do not hesitate to contact us. You will find the relevant contact information at the end of this user manual.

8 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance with your local waste regulations.

If you have any questions, please contact PCE Instruments.
