Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
Save all warnings and instructions for future reference.
1. Electrical shock can cause death or injury! NEVER TOUCH exposed conductors of electricity.
2. Inspect the Voltmeter before use. In addition to a general inspection, look specifically for:
a. Pay special attention to the insulation protecting the connectors.
b. Check the probes for exposed metal, damaged insulation, and continuity.
c. Replace damaged probes immediately, before use.
3. Do not use the Voltmeter if:
a. The electrodes (probes) are damaged in any way.
b. The interface cable between the electrodes (probes) is damaged.
c. The outer surface of the electrodes (probes) is grimy.
d. Any abnormal operation is detected. (If in doubt about the condition of the meter, have it
serviced.)
4. Never touch the interface cable between the two electrodes (probes) of the meter.
5. Observe work area conditions. Do not test voltages in damp or wet locations. Don’t expose to
rain. Keep work area clean and well lit.
6. Do not connect the device to HV permanently. (3 minutes max.)
7. Don't work alone - in the event of an emergency another person's presence may be essential.
8. In the event that moisture or water permeates the device, disconnect the device instantly and
contact manufacturer.
9. All safety measures that are obligatory in distribution companies in connection with 33kV
networks must be taken operating the meter
10. The maximum voltage to be connected to the device is 33 kV AC. Higher voltages will cause
damages to the device and put the user`s life at risk.
11. Use caution when working near voltages around 33kV AC. Voltages this high present a risk of
electric shock.
12. Stay alert. Watch what you are doing. Use common sense. Do not operate any meter when
you are tired.

13. Do not operate meter if under the influence of alcohol or drugs. Read warning labels on
prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there
is any doubt, do not operate the meter.
14. People with pacemakers should consult their physician(s) before use. Electromagnetic fields
in close proximity to heart pacemaker could cause pacemaker interference or pacemaker
failure.
15. Store idle equipment. When not in use, meters must be stored in a dry location to decrease
exposure to moisture. Lock up meters and keep out of reach of children.

Operating Instructions
( ENT refers to the middle button and means ENTER)
I. Voltage measurement
Firstly, install the Y-shaped probes on the probes; then, do the following steps:
1. Turn the switch on the electrodes (probes) on.
The green LED indicates the machine is turned on.
2. Turn the receiver on. The main menu appears After 5 seconds.

3. Push ENT and enter measurement menu. By connection of the two components, the
green LED starts flashing (handshaking) and “less than 1 kV” will appear in voltage
section.
4. The distance between the transmitter (probe) and the receiver is 21m at most.
5. By connection loss, the green LED stops flashing and voltage number will disappear.
Then “error.com” will appear on the screen. Pushing the ENT (dial), transmitter, and
receiver will connect (if not, turn off the receiver and transmitter for 11 seconds). Time,
date and battery level are also shown on the screen.
6. Connect the electrodes (probes) to the conductor (airline, ground post …). Voltage
amount is shown on the screen
Note: use an elevator for airlines.
II. Double-Phase Measuring
For double-phase measuring, do the following steps:
1. Instead of one of the Y-shaped probes, install the hook on the probe.
2. Use an elevator to get to the place of two airlines that you want to make them parallel
(mind the line confines)
3. Turn both the device and the receiver on.
4. Connect the probe with a hook to a phase of the first line in an appropriate place.
5. Connect the other probe to each of the three phases of the second line sequentially.
6. Whenever the red LED turns on and the device beeps, it indicates that the voltage of the
two phases is not the same. On the contrary, if the red LED DOES NOT turn on and the
device DOES NOT beep it indicates that the voltage of the two phases is similar, thus
the they could be connected.
III.Recording the measured values:
1. To record the measured values, push the ENT to enter recording page.
2. On the recording page, you should firstly enter the location name. The name could be at
