Precautions for NF-826
1. The working temperature of this Cable Locator is 0-40°C (32-104°F).
2. To avoid damage , this device should be protected against excessive mechanical vibration during handling or use, especially dropping.
3. Only professionals are allowed to calibrate and repair this instrument.
4. Prior to usage, inspect the instrument and the test lead in use for external damage. Please ensure that the instrument and the test lead in use are intact. The instrument should not be used unless all the functions of the instrument are well prepared for work.
5. When using the instrument, the rated voltage of the tested line should not exceed the rated voltage specified in the technical specifications of this Cable Locator.
6. Keep the instrument off direct sunlight to ensure perfect functioning and long service life.
7. If the instrument is subject to an extremely high electromagnetic field, its functioning ability may be impaired.
8. Only use batteries as described in the technical data section. 1) Before using a locator that has been placed or transported under extreme climate conditions, please place it under a new favorable environment for a certain period.
2) When the transmitter is connected with live mains , if the Grounding hole of the transmitter is connected with protective ground phase, the current leakage (if any) in the power supply line may join the circuit current of the transmitter, leading to tripping of the leakage circuit breaker, i.e. tripping of FI/RCD.
3) Please maintain the original package well for later mailing (such as for calibration of the instrument).

FAQ OF 826
Q1: What is the meaning of the high voltage symbol displayed on the receiver screen when searching line 826?
A1:The receiver can also normally detect alternating current (similar to NCV function) in line-seeking mode. When the high-voltage symbol is displayed, it indicates that there is strong alternating current around, so it should be paid attention to safety.
Q2: 826 bipolar applications can be charged cable testing?
A2:In a voltage line, the transmitter can not only transmit information signals, but also measure cable voltage.
Q3: Can 826 find breakpoints with two emitters?
A3:Yes, two emitters are set as different codes, and the two emitters are connected at both ends of the breakpoint in accordance with the breakpoint wiring mode, then two emitters' codes can be received at both ends of the breakpoint.
Q4: Can 826 detect metal water pipes buried in the ground and connected to protected areas?
A4:No, the metal pipe to be detected should not be connected to the protected area, and there should be a large resistance between it and the soil (if the resistance is too small, the detection distance will be very small); (that is, if the metal pipe to be detected is not protected and there should be a large resistance between it and the soil, it can be detected).
Q5: 826 receiver detector pen close to indoor 220V/50Hz AC, speaker no sound? What's the reason?
A5:First, confirm whether to switch to NCV mode, and second, check whether the mute function is enabled.
Q6: Can 826 line search with charge? How many volts can you measure?
A6:This model can be charged line search, the voltage test can be measured to 400 volts.
Q7: If it is an armored cable, NF-826 can find the breakpoint of the cable?
A7:Can't find it, because the surface layer is too thick to isolate the signal, so that it is difficult to find the breakpoint of the cable.
Q8:If the cable is buried in the frozen ground, why is there no sound when the 826 is testing?
A8:The operating temperature range of 826 is 0 degrees -40 degrees, and the maximum relative humidity is 80%. Another reason is that the grounding environment does not meet the requirements.
Q9: What is the detection depth of these three models of 820,822,826?
A9:The detection depth of the 820 is 1.5 meters, the detection depth of the 822 is 0.3 meters, and the detection depth of the 826 is 1.5 meters to 2 meters. The difference in the detection environment also affects the depth of the detection. In addition, 820 and 822 can only find directions, and 826 can find short-circuit points and break points.
Q10: Can 826 find short circuit/break point of cable (multi-core)?
A10:Yes, this function is mainly used to find the short circuit/breakpoint of the cable.
Q11: 826 detected the location of the short-circuit point, there is also a sound?
A11:It can be adjusted to manual mode and the sensitivity is lowered, so that the position of the short-circuit point will be found more accurately.
Q12: 826 can measure the maximum depth?
A12:Unipolar application is about 0-1M, bipolar application is about 0-0.5M, and the single loop can reach 2.5M.
Q13: 822, 820, 826 can be connected to 380V power?
A14:Can measure 400V strong current.
