I . Brief Introduction
ETCR9000 Series H/L Voltage Clamp Meter has broken through the traditional structure, which is specially well-designed for measuring high voltage current, adopting the latest CT technology and integrated mask digital technology, formed by composition of a special use clamp meter with a high-voltage insulation rod, as to ETCR9000B type --- wireless transmission
of test data, it is equipped with wireless receivers, which can receive measured data within 30 meters line. If not using an insulation rod, it can be also used as a high precision low-voltage clamp meter, or an alternating current meter, which can accurately measure 0.1mA of current or leakage current.
ETCR9000 Series H/L Voltage Clamp Meter has an innovative integrated design between transducer clamp and transducer domain, ensuring the high-precision, high-reliability, and high-stability on constant test perennially.
ETCR9000 Series H/L Voltage Clamp Meter is connected with insulation rod, which can be used for measuring high voltage current that is below 60KV, on-line current measurement, also having peak maintenance, data preservation, data storage, wireless transmission and other functions, and its special clamp meter can make it easier for clamping or evacuating the tested wire through pressing or pulling back the insulation rod, time-saving and fast, widely used in transformer substation, power plant, industrial and mining enterprises as well as the inspection station and electrician maintenance departments for electrical current detection and field electrical operations. It can also replace the H/L voltage transforming ratio tester, that is, to detect the high and low current for primary circuit and secondary circuit separately, and then calculate to conclude the change of high and low pressure.
The insulation rod is light and convenient, with the advantages of anti-moisture, high temperature resistance, anti-impact, bending resistance, high insulation, flexibility and other characteristics.

According to manual instructions to install the battery
A. Tester Operation
1. Power On/Off
Press POWER button to power on, the instrument will displays the LCD screen, entering normal testing mode. If
LCD display is relatively dark after power on, it is possible that battery voltage is a bit lower. Please replace battery. 15 minutes after powering on the meter, if it remains idle, an auto-power off procedure starts to preserve the battery life and
LCD will continue flash until the complete switch off takes place after 30 seconds. In case of LCD continuous flash, press POWER button, then the meter will continue to work.
Under HOLD mode, press POWER button for power off.
Under general test mode, press POWER button to power off.
Under PEAK testing mode,press POWE button to power off. Under data reference mode, firstly press POWER button for more than 3 seconds to exit from data reference mode, returning to normal test mode, then press POWER button to power off. During the exit from data access, it will display
“End” symbol.
2. General Test
High voltage, extremely dangerous! It must be operated by qualified staff that has acquired authority. The operator must strictly abide by the
-10-
safety rules. Otherwise, there is electric injury danger, causing personal damage or casualty accident.
Dangerous! It cannot be used to measure the circuit over 35KV voltage. Otherwise, there is electric injury danger, causing personal damage or equipment damage.
Dangerous! It cannot be used to measure the circuit over 1000A voltage. Otherwise, there is electric injury danger, causing personal damage or equipment damage.
General Test: In the process of test, LCD will display the tested current value real time, and LCD data will vary with the current change. When the tester is removed away from the lead on test, it does not preserve the test result, LCD display will return to zero.
In normal testing mode, it is suitable for close distance measurement, convenient for circuit test by direct read of LCD data.
Before test, firstly to connect insulation rod, which must be connected in right position, and then to connect tester, avoiding the impact of meter to ground surface.
Make sure to use specially equipped insulation rod to connect with the meter.
After test, it should incline the insulation rod accordingly on drawing in. Firstly to tear down the tester and then the insulation rod, avoiding the impact of meter to ground surface.
After normal boot, place the lead in the middle of clamp transducer domain, as shown in Figure A, with the meter transducer domain perpendicular to the lead, pushing the meter forwards to clamp the lead on test, showing the result on LCD display. If showing "OL A", it means the lead current on test has exceeded the maximum volume on the level.
Please select a higher gear level or a meter with greater measurement limit.
To pull backwards can make the meter remove from the
-11-
lead on teat, as shown in Figure C, please try to keep the meter transducer domain perpendicular to the lead when moving away .
Under HOLD mode, press HOLD button to cancel HOLD function, and return to normal testing mode.
Under data reference mode, press POWER button for more than 3 seconds to exit from data reference mode, returning to normal testing mode.
Under PEAK testing mode, press POWER button to exit from PEAK testing mode, returning to normal testing mode.
After data deletion, it will return to normal testing mode automatically.
Attention! For the sake of safety, when test has been finished, please remove the meter away from the lead on test.
-12-
3. PEAK Test
PEAK test: the maximum current test. The meter will make automatic comparison on the changes in measured current, indicating the maximum value and maintain it, when the meter is removed away from the lead on test, the test result will be kept consistently, suitable for the circuit test on those LCD data hard to be read directly.
Under the normal testing mode, press PEAK button,
PEAK indication light will be bright,,enter PEAK testing mode.
That means the meter will display and automatically keep the maximum value in the test.
Under any other mode, it must be returned to normal testing mode, and then make PEAK testing according to the above operation.
Press POWER button to exit from PEAK testing mode, returning to normal testing mode, and it will display “End” symbol during the exit.
4. Data Maintenance
Under normal testing mode, press HOLD button to keep
LCD display, “HOLD” symbol displays. Press HOLD button again to release data lock, returning to normal testing mode, and
“HOLD” symbol disappears.
5. Data Memory
Under normal testing mode, press HOLD to storage data, at the same time, Meter will automatically form serial numbers, and memory the current preserved data. During the storage,
“MEM” symbol will show once by flash. This meter can memory 99 groups of data, in case of full storage, “FULL” symbol will display by flash continuously, and it cannot continue to memory until cleaning out the previous memory.
6. Data Reference
Under normal testing mode, press PEAK + POWER button to enter data reference mode, display ing “MR” symbol, meanwhile, it will automatically display data saved in the group
01. Then press PEAK or POWER button to read the stored
-13-
data by turning upwards or downwards in cycle. It will return to the group 1’s data automatically after reaching the last group’s data in storage.
Press HOLD button to exit from data reference mode, returning to normal testing mode. During the exit, it will display
“End” symbol.
7. Data Deletion
Under data reference mode, press PEAK + POWER button to delete all the data in storage, and return to normal testing mode. During the deletion of data, it will display
“dEL” symbol.
*8. Data Transmission
B Type: has the function of wireless data transmission.
When the Meter under testing mode, the test result will be transferred to receiver by wireless transmission and the receiver will display test result real time, being clear at a glance.
Only under testing mode, the meter will transmit, If the receiver has not received emission signals, it will display
“no -
-
” symbol dynamically.
B Type: Transferred
ETCR9000B Type: Wireless transmission test data, a straight-line distance of about 30 meters, can penetrate the floor to receive data.
B .Operation of Receiver
