1. ABOUT PITE 3830
1.1 Main Unit & Signal Receiver
Main unit contains: carrying case, LCD screen, 6 buttons, 1 USB socket, 2 sockets for insulation test, 2
sockets for grounding test, 1 socket for main unit charging and 1 main unit power switch.
Sample picture of Main Unit is as below:
Fig. 1.1.1
Sample picture of Signal Receiver is as below:
Fig. 1.1.2
325Hz signal receiver has frequency options for Selected Hz and Full Hz. They are applied in different
environments.
Selected Hz means only one frequency (325Hz) is used during ground fault location. Full Hz indicates
that the signal receiver may use different frequencies available to pinpoint ground fault. In this case,
signal will be comparatively stronger than that of selected Hz. However it (Full Hz) may be interfered by
surrounding circumstances if there are other equipments running with different frequencies. In these

PITE 3830 Ground-fault Locator User Manual

complicated circumstances, Full Hz may not be as accurate as Selected Hz.
Details about testing signal indicator
Fig. 1.1.3 shows the meaning of signal indicator. This is one way to check the ground fault. We will
introduce in 3.3 Ground-Fault Location in details.
As the signal receiver is switched on, the power indicator (in green) is on.
When battery is full charged, the second grid is dim. As the battery is low, the light will be on (in green).
You are suggested to charge it timely to ensure its performance.
When signal is detected in the circuit, signal indicators will be on in the consequence of green, orange
and red from the 3rd grid to the 7th. Signal light of the 4th grid is strong than the 3rd, and so forth like Fig
1.1.4.
NOTE: Due to signal interference at the beginning, the receiver may be in full signal right after it is
switched on. Wait for a few seconds, the signal will be normal.

1.2 Accessories
All the following accessories are contained in the carrying case. After receiving the unit from your
supplier, please make sure you have the following items:
1.3 Function
1) Ground fault location
It tests the insulation status of device in DC system. When busbar insulation has breakage in certain
point, its resistance will reduce to be lower than required. It may even cause power break-off which is
costly to repair. Fast location and elimination of insulation fault will be significant for electricians and

technicians.
By using PITE 3830 Ground-Fault Locator, you could fast pinpoint the breakage.
System composition: main unit of Ground –fault Locator and a signal receiver (clamp-shaped)
Basic theory:
In the breakage of busbar, there is loose of electricity to the ground and thus generate a faulty
“grounding”. When testing leads of PITE 3830 are connected to the ground and busbar, there will be a
return circuit (see Fig 2.2.2 in 2.2.2 Connection for Grounding Location).
Signal generator (main unit) will send a low-frequency voltage signal of 0.1Hz～1000Hz between the
testing target and grounding malfunctioned circuit. The breaking point will generate leaking current. As
the grounding receiver (signal receiver) moves in the circuit, different points in the circuit will have
different reaction in the indication of sound warning and light flashing. Based on the sound volume in
the signal receiver, it will pinpoint the grounding fault. For detailed operation, please refer to 3.3
Ground-Fault Location.
2) Insulation test
It tests and records voltage and insulation status for tested target.
3) Data management function
With the management software, you could check detailed wave, have good follow-up for insulation
status, find insulation defection in time and predict insulation life span of equipments.
1.4 Feature
♦Insulation tester and ground fault locator, two function in one

2.1 Preparation
Make sure the targeted insulation resistance is in the testing range. To avoid explosion, please do
not operate the device near inflammable and explosive materials.
2.2 Main Unit connection
One end of the testing lead is connected with the alligator and the other with “Insulation” socket or
“Grounding” socket in PITE 3830 main unit. For insulation test (including voltage test and insulation
testing), the testing leads are connected with insulation test socket. For grounding fault location,
connect the leads with grounding socket in main unit. Make sure the colors should be in accordance
with each other, red socket with red lead and black with black.

2.2.1 Connection for Insulation Test
For insulation test (including tests for voltage and insulation), one end of testing lead is connected with
alligator and the other end with “Insulation” socket in main unit. Alligators are clipped on the testing
target before main unit is on for measurement.
2.2.2 Connection for Grounding Location
In the function of ground fault location, main unit plays the role as signal generator. And grounding
receiver is the signal receiver. For its connection, please change the testing leads to the “Grounding”
socket in main unit. The testing alligators are the output ends of signal generator. They are connected
with busbar and ground. There are two different ways of connection based on which busbar has
breakage:
1). Red testing alligator is connected with positive busbar. Black alligator is connected with ground.
In this case, positive busbar has breakage.
2). Red testing alligator is connected with ground. And black alligator is connected with negative busbar.
In this case, negative busbar has breakage.
Wiring and operation flowchart for ground fault location is as below. We will describe this in details in
3.3 Ground-Fault Location.
Fig. 2.2.2
2.2.3 Other Connection
USB socket on the main unit panel is for connecting USB drive for data transfer and system update.

3.2.2 Insulation Measurement
Select “Test Insul” in insulation measurement menu. You will be required to input device number as
below. Use arrow keys for the setting of device number. This numbers are self-defined which could be
reviewed in the sector of data management.
Fig.3.2.2
Press OK to confirm the device number setting. You will then find 4 options for tested voltage: 100V,
500V, 250V and 1000V. These voltage levels are used in standard configuration of PITE 3830, other
voltage types could be made in specific units.
Fig. 3.2.2.1
Select the relative voltage for your circuit and press OK for confirmation. Positive and negative
Insulated binding posts will output the voltage as selected. Wait for a little while; you will see the
following screen. Resistance value indicates the testing result.
Fig.3.2.2.2
NOTE: Voltage injection is related to voltage-withstand of your testing target. Voltage input is always 2
to 3 times of nominal voltage. For example, if nominal voltage of testing target is 48V, you could select
100V in above option. If nominal voltage is 110V, you could select 220V. The higher voltage you select,
the higher accuracy you may get. However, at the same time, you may get testing target punctuated if
selected voltage is too high.
