Brief Introduction

HZRC9000B 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 HZCR9000B type — wireless transmission of test data, it is equipped with wireless receivers, which can receive measured data within 30 meters line. If not using aninsulationrod, it can be also used as a high precision low voltage clamp meter, or an alternating current meter, which can accurately measure 0.01mA of current or leakage current.

HZRC9000B Series H/L Voltage Clamp Meter has an innovative integrated design betweentransducer clamp and transducer domain, ensuring the high-precision, high-reliability, and high-stabilityon constant test perennially

HZRC9000B Series H/L Voltage Clamp Meter is connected with insulation rod, which canbeusedfor measuring high voltage current that is below 60KV, on-line current measurement, also having peakmaintenance, data preservation, data storage, wireless transmission and other functions, anditsspecial 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 maintenancedepartments for electrical current detection and field electrical operations. It can also replacetheH/Lvoltage transforming ratio tester, that is, to detect the high and low current for primary circuit andsecondary circuit separately, and then calculate to conclude the change of high and lowpressure. Theinsulation rod is light and convenient, with the advantages of anti moisture, high temperatureresistance,anti-impact, bending resistance, high insulation, flexibility andother characteristics.

Tester Operation

Power On/Off

Press button to power on, the instrument will displays the LCD screen, enteringnormal
testing mode. If LCD display is relatively dark after power on, it is possible that battery voltageisabitlower. Please replace battery. 15 minutes after powering on the meter, if it remainsidle, anauto-power off procedure starts to preserve the battery life and LCD will continue flashuntil thecomplete 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 button for power off.

Under general test mode, press button to power off. Under PEAK testing mode press POWE button to power off. Under data reference mode, firstly press button for more than 3 seconds to exit from data reference mode, returning to normal test mode, then press button to power off. During the exit from data access, it will display “End” symbol.

General Test

High voltage, extremely dangerous! It must be operated by qualified staff that hasacquired authority. The operator must strictly abide by the 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 1200A voltage. Other wise, 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 testby direct read of LCD data.

Before test, firstly to connect insulation rod, which must be connected inright 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 b, 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 ameter with greater measurement limit.

To pull backwards can make the meter remove from the lead on teat, as shown in Figure C , please try to keep the meter transducer domain perpendicular to the lead when moving away
Instruction

Under HOLD mode, press HOLD button to cancel HOLD function, and return to normal testingmode. Under data reference mode, press POWER button for more than 3 seconds to exit fromdatareference mode, returning to normal testing mode. Under PEAK testing mode, press POWER button to exit from PEAK testing mode, returningtonormal 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

PEAK Test

PEAK test: the maximum current test. The meter will make automatic comparisononthechanges in measured current, indicating the maximum value and maintain it, when themeterisremoved away from the lead on test, the test result will be kept consistently, suitable for thecircuittest on those LCD data hard to be read directly.

Under the normal testing mode, press PEAK button PEAK indication light will be bright,，enterPEAK testing mode. That means the meter will display and automatically keep the maximumvalue in the test.

Under any other mode, it must be returned to normal testing mode, and then make PEAKtestingaccording to the above operation.

Press button to exit from PEAK testing mode, returning to normal testing mode, anditwill display “End” symbol during the exit.

Data Maintenance

Under normal testing mode, press button to keep LCD display, “ ” symbol displays.Press HOLD button again to release data lock, returning to normal testing mode, and“ ”symbol disappears.

Data Memory

Under normal testing mode, press 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

Data Reference

Under normal testing mode, press + button to enter data referencemode,displaying “MR” symbol, meanwhile, it will automatically display data saved in the group01. Thenpress or button to read the stored data by turning upwards or downwards incycle. Itwill 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.

Data Deletion

Under data reference mode, press + button to delete all the data in storage, andreturn to normal testing mode. During the deletion of data, it will display “dEL” symbol.

Data Transmission

B Type: has the function of wireless data transmission. When the Meter under testingmode, thetest result will be transferred to receiver by wireless transmission and the receiver will displaytestresult real time, being clear at a glance. Only under testing mode, the meter will transmit, If the receiver has not receivedemissionsignals, it will display “no – -” symbol dynamically. B Type: Transferred

HZCR9000B Type: Wireless transmission test data, a straight-line distance of about 30meters,can penetrate the floor to receive data.

Replacing Batteries

Warning! In case that the battery’s cover board is not well closed, it is forbidden to make test. Otherwise, it is dangerous.

Pay attention to the polarity of battery, in case of damage to the meter.

Do not mix in the use of new and old batteries

When the battery voltage is below 4.8V, the meter will display “ ” symbol, indicating the batteries have no sufficient power content. Please replace batteries.
Power off, to make sure the meter is under the state of power off. To loosen two screws of the battery cover board, open the cover board to replace brand-new qualified batteries on. It should pay special attention on the battery specification and polarity, cover the board well and fasten the two screws.
