• The clamp meter must be operated only by persons who understand the danger of shock hazards and are aware of the necessary safety precautions. Shock hazards exist wherever voltages of more than 30V (TRMS) are present.
• Do not work alone in shock hazardous environment while carrying out measurement.
• The maximum permissible voltage between any of the terminal sockets (7) and ground is 1000V AC and 1500V DC.
• Take into account that unexpected voltages can occur on device under test (e. g. defective instrument). For example, capacitors may be charged to a dangerously high voltage.
• Verify that the test leads are in good condition, i.e. no cracked insulation, no open circuits in the leads or connectors.
• This clamp meter must not be used for measurements on circuits with corona discharge (high voltage).
• Be particularly careful when measuring on HF circuits. Dangerous composite voltages may exist there.
• Measurements under moist environmental conditions are not permitted.
• Do not overload the measuring ranges beyond their allowable capacities. Limit values are given in specifications. Ref. Chapter 16.
• Please verify the performance of clamp meter after repairing of the meter, before using it for actual measurement.

When it is realized that the safe operation is no longer possible, take the meter out of service and secure it against accidental use. Safe operation may not be possible,

• l when the meter shows obvious signs of damage.
• l when the meter no longer functions correctly.
• l after prolonged storage in adverse conditions.
• l due to severe stress during transportation.

Switching the Clamp meter “ON” Battery

We have already fitted your meter with a 9V flat cell battery according to IEC 6 F22 or IEC6LR61. It is ready for operation. Before you use the meter for the first time or after storage, refer to Section “18.1 Maintenance-Battery”

Switching the meter “ON”

• Press the “ON/OFF” pushbutton (2). Switch-“ON” is acknowledged by a sound signal. As long as you keep the pushbutton pressed, all segments of the liquid crystal display (LCD) will appear. The LCD is shown behind cover page
  After the push button is released, the meter is ready for operation.

Note:
Electric discharges and high-frequency influence may cause incorrect information to be displayed and block the measuring process. Reset the meter by switching it OFF and ON again otherwise, check the battery connections.
Disconnect the clamp meter from the measuring circuit before you open it, and see section “18. Maintenance”.

Automatic TURN-OFF
The meter turns off automatically, when the measured value remains constant (variations of the measured value < + 2digits) for about 10 minutes and when neither a pushbutton nor the function selector switch is operated during that time.

How to prevent automatic TURN-OFF
In order to prevent automatic “TURN OFF” select “CONTINUOUSLY ON” mode. For this, press yellow multi-function pushbutton (5) and the “ON/OFF” pushbutton (2) together. The function “CONTINUOUSLY ON” is shown on the LCD(1) by the symbol ON (8).

Turning the multimeter OFF
Press the “ON/OFF” pushbutton (2).

Function and range selection

Autorunning

The multimeters feature autorunning for all measuring ranges with the exception of the 30mV ,300mV ranges. Autorunning is automatically selected after switching the multimeter ON. According to the measured quantity applied, the multimeter automatically selects the measuring range which gives the best resolution. When switching to frequency measurement and ratio measurement the previously selected voltage measuring range is maintained.

The meter switches automatically to:

• the next higher range at + (3099 digits+1digit)
• the next lower range at + (240/280 digits-1digit)

Manual range selection

You can switch OFF autorunning and select the ranges manually according to the table on the following page.
Manual mode is switched OFF when push button AUTO/MAN is pressed (4) for approximately 1s, when the function selector switch (6) is operated,
or when the meter is turned OFF and ON again.
When switching back to autorunning from 30mV or 300mV ranges, 3 V range is automatically selected.

Liquid crystal display

Digital display

The digital display (9) shows the measured value with correct location of decimal point and sign. The selected measuring Unit(12) and the function(11)
are simultaneously displayed. When measuring DC quantities, a minus sign appears in front of the digits, when the positive pole of the measured quantity is applied to the” “input terminal. When upper range limit 3099 (on the range :1999), is exceeded then “OL” is displayed.
With V and Ω measurements, the digital display is updated two times per second.

Analog indication

The analog indication with pointer presentation gives the dynamic response of a moving-coil movement and is updated 20 times per second, when measuring V and Ω. Analog indication is of particular advantage when observing variations of measured values and for calibration procedures.
The analog indicator has its own polarity indication. When measuring DC quantities, the analog scale(15) has a negative range of 4 scale divisions so that variations of the measured values around” zero” cane observed exactly. When the measured value exceeds the range of indication, the left triangle(16) is shown before the polarity of the analog indicator switches over after approximately 0.7s.The over range indication on the measuring range(>3099 digits, on the range >1999)is shown by the right triangle(13).

Backlight (Optional)

The instrument is provided with user selectable Backlight for taking measurements in poor lighting conditions/dark areas.

Switching the Backlight ON
By pressing “AUTO/MAN “and” HOLD” keys simultaneously the Backlight can be switched ON.

Switching the Backlight OFF
By pressing “AUTO/MAN” and “HOLD” keys simultaneously the Backlight can be switched OFF.

Data “HOLD” facility

The HOLD function allows to automatically hold the measured values. The meter holds the measured value on the digital display with a sound signal and displays “ HOLD ” on LCD display (10). The probes or clamp can now be removed from the measuring point and the measured value on the digital display(9) can be read. The analog indication is not influenced by the data HOLD.
The actual measured value can still be noted/read.
Note that with a held digital display, the location of the decimal point is also held. With autorunning selected, the measuring range of the analog indicator is no longer known.
Note: Hold function is not available in function 0C and 30 mV and 300mV range sin function V .

To activate “HOLD” function momentarily, press the HOLD key.
As long as the data HOLD function is active, manual range selection is not possible. The data HOLD function is switched OFF, when

• The “HOLD” pushbutton(3) is pressed for approx.1s.This is acknowledged by 2 sound signals.
• The function selector switch (6) is operated or
• The multimeter is turned OFF and ON again.

Minimum value and Maximum value “MIN / MAX” storage facility.

With the MIN/MAX function, you can hold the minimum and the maximum measured value which was applied to the input of the Clamp Meter after activating MIN/MAX function. The most important application is the determination of the minimum and the maximum value for long-term monitoring of measured quantities. MIN/MAX does not influence the analog indication The actual measured value can still be noted/read. Apply the measured quantity to the meter and select the measuring range prior to activating the MIN/MAX function.
With the function activated, you can select the measuring ranges manually, if you switch to another range, the stored MIN/MAX values are cleared.

The MIN/MAX function is switched OFF, when the MIN/MAX push button (3) is pressed for approximately 1s, or when the function selector switch (6) is operated, or when the meter is turned OFF and ON again.

Voltage measurement

• According to the voltage to be measured, set the function selector switch(6) to V~ ,V
• Connect the test leads as shown. The “ “ socket should be connected to the lowest potential ground available.

Notes:
The 30 mV and 300 mV measuring ranges can only be selected manually with the “AUTO/MAN” push button(4).
On the 1000 V range, an intermittent sound signal warns you, when the measured value exceeds the upper range limit.

Unique design for safety and comfort

In conventional clamp meters display, keys and clamp jaws are in the same plane. When current measurement is to be done on vertical bus bars, over head cables, cables in congested places user connects the clamp meter but the keys and display may not be visible, hence user is not able to take the readings or operate the keys.
To over come the above mentioned problem the Clamp meter has a unique feature called “Rotary mechanism for clamp jaws”. In this, the clamp jaws are rotating. Hence it is possible to align the clamp jaws as the orientation of bus bar/conductor while keeping Display and keys facing the user, so that user can take the readings and operate the keys.
Rotary clamp jaws can be rotated at different angles with the step of 30º maximum, up to 90º in both clock-wise as well as anti-clock wise direction as shown in figure c .

Normally, it is difficult to access the middle busbar for current measurement. With “Rotary mechanism for clamp jaws” it is easy to access middle bus bar, while keeping display and keys facing towards the user as shown in figure d on previous page.

Safe trigger mechanism

The conventional clamp meters have trigger mechanism either near to left jaw or right jaw. While taking measurements on bare bus bar or bare conductor the user’s hand comes very close to bare bus bar/conductor, which increases the risk of electric shocks to the user.
Also in conventional clamp meters trigger is operated with single finger, usually a thumb which causes fatigue to the user while opening or closing the clamp jaws.
To over come the above mentioned problems, The Clamp meter has
a unique feature called “Safe trigger mechanism” in which trigger is located at bottom side of the clamp meter and far away from the jaws and hence the bus bar.
So user’s hand is at safer distance from bare conductors, hence minimizes the risk of electric shock to the user. This is shown in figure e.
Also trigger can be comfortably operated with more than one finger which eliminates fatigue to the user.
For best accuracy keep the conductor at center of the jaw as shown in figure e.

User’s hand is at safer distance from bare bus bar/conductor.

Empty Positions

Empty positions on dial indicates no function is available on these positions. The digital display will look like as in figure below. There are three empty positions present on the dial.
