Danger—-identifies conditions and actions that are likely to pose serious or fatal hazards .
 Warning–identifies conditions and actions that may pose serious or fatal hazards.
Caution—-identifies conditions and actions that may pose minor injury or damage the instrument.

Danger

• The RCD test function of this instrument is only applicable to single-phase 230V /50Hz (power voltage range: 195-253V) circuits; the measuring voltage range of this instrument is 30V-600V, 45Hz-65Hz.
• Before using the instrument, please check the test lead carefully. If the test lead is cracked and the metal wires are bare, do not use it. otherwise, serious or fatal hazards are likely to be posed.
• When testing, only under safe conditions can you finger the test lead.
• When testing, do not touch any exposed leads.
• After completing the test, please disconnect the test lead from the power immediately.

Warning

• During the test, never open the casing of the instrument because of the dangerous voltage in it. In the event of a malfunction, please refer it to a professional for
  inspection and repair.

• If there are any anomalies (such as imperfect display, unexpected test value, damaged casing, noise during testing, etc.) of the instrument, please hand ii over to a professional for repair before use.

• Do not use the instrument if your hands are wet.

Caution

• To ensure safety, please use the certified test lead provided by Uni-Trend. It is forbidden to use other test leads.
• Do not expose the instrument to harsh environments such as the sun, extreme temperatures and humidity.

• If the instrument is wet, dry it before storage.

Warnings:

1. lf a possible voltage between the protective conductor and earth will influence the measurements.
2. It needs to test the connection between the neutral point of the distribution system and earth before the test is started. A possible voltage between the N-conductor and the earth may influence the measurements.
3. The leakage currents in the circuit following the residual current protection device may influence the measurements.
4. When the fault voltage is over 50V, “Uf Hi” will be displayed and the test will stop. The voltage relates to the residual operating current of the protective device.
5. The earth electrode resistance of the measuring circuit probe cannot surpass 50.
6. The potential fields of other earthing installations may influence the measurement.
7. Special conditions in residual current protective devices of a particular shall be taken into consideration.
8. Equipment is connected downstream of a residual current protective device may cause a considerable extension of the operating lime.

V. Voltage Measurement

1. Please use the test leads which meet CAT Ill 600V, IEC 61010-031 :2015 requirement to test the voltage (The maximum voltage which being tested should be less than 600V). Test Lead connection method: Insert the red test lead into L ports and black test lead into N ports of the instrument being measured. (If the voltage is less than 250V, you can also use the 3 terminals of the test lead (but ii is not recommend). Test Lead connection method: Insert the three terminals of the test lead into the three corresponding ports of the instrument: Red into L, green into E and blue into N.)
2. Tum the dial to the corresponding test gear (VOLTS) of the voltage measurement function and start up the instrument.
3. Press the “L-N/L-PE” key to switch to L-N/L-PE voltage display.
4. Press the “VOLT/FREQ” key to switch to voltage/frequency display.

VI. RCD Test

1. Test Lead Connection
   Insert the three terminals of the test lead into the three corresponding ports of the instrument: Red into L, green into E and blue into N. Turn the dial to the corresponding test gear (x1/2, x1, x5 and AUTO RAMP) of the RCD test function and start up the instrument. Then connect the plug of the test lead to the circuit to be tested (power socket 230V/50Hz).

2. Wiring Check
   Check the wiring status by identifying the L-PE, L-N and N-PE symbols. When the wiring is correct, the L-PE and L-N symbols on the left side of the LCD are always on and the N-PE is off. Otherwise, the wiring is incorrect; check and correct the relevant wiring until correct wiring indication is obtained.
   Caution: Reverse connection between E and N ports during wiring check may cause RCD to trip. In this case, please check and correct the relevant wiring until the wiring indication is obtained before you proceed to next operation.
   Danger
   If the wiring is incorrect, do not proceed with the test (press the TEST key). Otherwise, ii very likely causes false test results or other hazards.

3. Press the “Ian” key to switch so that the trip current (I6n) matches the rated trip current indicated on the RCD (residual current device). The set trip current value will be displayed at the bottom of the LCD.
   Default value: Ian—-30mA
   0/180—0°

4. Taking RCD Test

• 1. Set test parameters.
     Non-tripping test—– x1/2: Maximum trip time up to 2000ms
     Tripping test —– x1: Maximum trip time up to 1000ms (except 500mA)
     Tripping test—— x1(500mA): Maximum trip time up to 300ms
     Fast tripping lest —— x5 (only for 10, 20, 30mA): Maximum trip time up to 40ms
     AUTO RAMP test—- 20%-110% of rated trip current (I6n)
     Maximum trip time up to 300ms
• 2. Press the “TEST” key.
     Non-tripping test —–The RCD should not trip.
     Tripping test —– The RCD should trip.
     x5 fast tripping test —– The RCD should trip.
     AUTO RAMP test —– The RCD should trip; trip time and trip current should be displayed simultaneously.
• 3. Press the “PHASE/UL” key to alter the phase and repeat step 2 above to determine the fastest trip lime (When the “PHASE/UL” key is pressed, the set value is cyclically switched in the order of UL25V 0°, UL25V 180°, UL50V 180° and UL50V 0°).
• 4. Press the “PHASE/UL” key to alter the phase and repeat step 2) again.
• 5. After completing the test, please disconnect the test lead from the power immediately.

Danger

• Do not touch any exposed metal or leads during the operation of these tests.

• Internal components in the instrument may get hot during testing. If the instrument is operated continuously for a long time, it very likely causes damage to the device or other hazards. Therefore, it is not recommended to use the instrument for a long period of continuous testing on production lines in RCD factories. It is only suitable for
  sampling precision testing.

• Trip current of 300mN500mA test (high current tripping test) only can be conducted every five minutes.

VII. Maintenance and Repair

1. Cleaning the Casing
   Clean the casing of the instrument gently with a dry cloth. Do not use alcohol or solvent as it is corrosive to the casing, especially the LCD. Please prevent the instrument from being wet.

2. Repair Please contact the after-sales service center or agent of Uni-Trend if the following issues occur.

• A. The casing of the instrument is broken or the components are damaged.
• B. LCD displays abnormally.
• C. Unexpected test data occur under normal use.
• D. The keys do not function normally.
