4 LCD Display

4.1 Digital Display

The digital display shows the measurement value, decimal point and sign. The selected unit of measure and type of current are displayed. A minus sign appears in front of the digits for the measurement of direct magnitudes, if the positive pole of the measurement magnitude is applied to the “

” input. A blinking “4000” appears if the measuring range upper limit of 3999 is exceeded.

The digital display is updated twice per second for V, A and

 measurements.

4.2 Analog Display

The analog bar display, which demonstrates the dynamic performance of a moving coil mechanism, is updated

20 times per second for V, A and

measurements. This is especially advantageous for the observation of measurement value fluctuations and for balancing.

5 Acoustic Signal

The following sequence steps are acknowledged by an acoustic signal:

• New measurement function selection

• Activation or deactivation of the following functions:

AUTO/MAN, MIN/MAX or HOLD

A repetitive acoustic signal indicates that a function cannot be selected, or an operator error.

6 Measurement Value Storage “HOLD”

By pressing the HOLD/ON key, the currently displayed measurement value can be “held”, and “Hold” is simultaneously displayed.

The Hold display is deactivated if:

• the Hold key is reactivated

• the selector switch is activated

• the multifunction key is activated for a change of function, e.g. AC  DC.

10 GMC-I Messtechnik GmbH

7 Storing Minimum or Maximum Values

“MIN/MAX” Hold

With the MIN/MAX function, you can “hold” either the minimum or the maximum measurement value which was present at the measuring instrument input immediately after activation of MIN or MAX. The most important application is the determination of the minimum or the maximum measurement value in the long-term observation of measurement magnitudes.

MIN/MAX has no influence on the analog display; it continues to display the current measurement value.

➭ Select the measurement function with the selector switch and, if appropriate, with the multifunction key.

➭ Select the measuring range manually. Automatic measuring range selection is not active in this mode.

➭ Connect the device under test as described in the following measurement instructions.

➭ Press the MIN/MAX key.

HOLD MIN is displayed. The measuring instrument continually updates and digitally displays the smallest occurring measurement value. This function remains active, and the respective minimum remains in storage, until the

MIN/MAX key is once again activated.

➭ Press the MIN/MAX key.

HOLD MAX is displayed. The measuring instrument continually updates and digitally displays the largest occurring measurement value. If the MIN/MAX key is activated again, this function is deactivated and the maximum value is deleted.



for electricians, which has an input resistance of approx. 400 k

. This reduces incorrect message displays due to capacitive interference during voltage measurements in power supply networks to a minimum.

➭ Connect the measurement cable as shown. Connector jack “

” should be grounded, and the second measuring cable with a higher potential connected to jack “V”.

Note!

The measuring rage 400 mV can only be selected manually with the “AUTO/MAN” key!

Attention!

Make certain that the current ranges (“mA” or

“A”) are deactivated and that the measurement cables are connected to the correct jacks, “V and

”, before connecting your multimeter for the measurement of voltage! If the fuse tripping limit values are exceeded due to operator error, both the operator and the instrument are in danger! Observe the voltage limit values as printed on the instrument!

➭ Select the respective voltage type which corresponds to the measuring magnitude by briefly pressing the multifunction key. Each activation of the key causes alternate switching between DC and AC, as well as aknowledgement by means of an acoustic signal. The symbols DC and AC indicate the selected voltage type in the LCD display.

After selection of this function with the selector switch, the voltage type AC is always activated

9 Current Measurement

Attention!

First switch off the power supply to the measuring circuit or the load component and discharge any capacitors which might be present.

➭ Select function A with the selector switch for currents

> 400 mA, or function mA for currents < 400 mA. Switch to the next highest measuring range, or activate automatic measuring range selection first for the measurement of currents of an unknown magnitude.

➭ Select the respective voltage type which corresponds to the measuring magnitude by briefly pressing the multifunction key. Each activation of the key causes alternate switching between DC and AC, as well as aknowledgement by means of an acoustic signal. The symbols DC and AC indicate the selected voltage type in the LCD display.

After selection of this function with the selector switch, the voltage type AC is always activated.

➭ Securely connect the measuring instrument in series to the load component as shown (without transition resistance).

Current Measurement Tips:

• The instrument may only be used in power installations when the nominal voltage of the installation does not exceed 600 V.

• The measuring circuit must be mechanically stable and protected against unintentional opening. Conductor cross sections and connection points must be substantial enough to avoid excessive overheating.

• In the 400 mA measuring range an intermittent acoustic signal warns you, if the measurement value has exceeded the measuring range upper limit value.

• Current ranges up to 400 mA are protected with a

FF1.6 A/600 V fuse in combination with power diodes up to a short-circuit current of 25 A. The breaking capacity of the fuse is equal to 50 kA at a nominal voltage of

600 V with resistive load.

• The 10 A current measuring range is protected with a

16 A/600 V fuse. The breaking capacity of the fuse is equal to 50 kA at a nominal voltage of 600 V with resistive load.

• If a fuse blows, eliminate the cause of the overload before placing the instrument back into operation!

• Fuse replacement is described in chapter 15.2, page 24.

9.1 AC Measurement with (Clip-On) Current Transformers

9.1.1

Transformer Output mA/A

Attention!

If current transformers are used at the secondary side in an open condition, e.g. due to defective or non-connected power cables, a blown device fuse or incorrect connection, dangerously high voltages can occur at the connections. For this reason, check to see if the measuring instrument’s current path and transformer’s secondary winding, which is connected to the instrument, complete a closed current circuit, and connect the transformer to the

 and mA or

A jacks.

Some current transformers (e.g. Z3511 ... 3514) include safety devices, which prevent dangerous voltage increases at open electrical circuits.

The maximum allowable operating voltage at the primary conductor is equal to the nominal voltage of the current transformer. When reading the measurement value, consider the transformation ration of the transformer, as well as additional display error.

9.1.2

Transformer Output mV/A (e. g. Z201A ... 203A)

Some transformers have a voltage output

(designation: mV/A). Consequently, the secondary connection must be connected to

 and V.

Delete Zero Balancing

➭ Press and hold the multifunction key and a two-fold acoustic signal acknowledges deletion, or

➭ Activate the selector switch or

➭ Switch the multimeter off.

13 Frequency Measurement

➭ Set the selector switch to Hz.

The frequency measurement mode is activated. Frequency is displayed at the LCD. Display occurs digitally only, and is expanded to 9999 digits. Only the autorange mode of operation is possible, because the AUTO/

MAN key is required for sensitivity selection.

➭ Apply the measurement magnitude in the same fashion as for voltage measurement.

➭ Select sensitivity with the AUTO/MAN key. You can switch between sensitivity levels of 0.1 V, 1 V and 10 mV.

After each activation of the AUTO/MAN key, the corresponding sensitivity level is displayed.

After selection of this function with the selector switch, the triggering threshold is always set to the highest level of sensitivity (10 mV).

15 Maintenance

Attention:

Disconnect the instrument from the measuring circuit before opening the instrument to replace the battery or the fuse !

15.1 Battery

Before initial start-up, or after storage of your instrument, make sure that no leakage has occurred at the instrument battery. Repeat this inspection at regular intervals.

If battery leakage has occurred, electrolyte from the battery must be carefully and completely removed and a new bat-

GMC-I Messtechnik GmbH 23

tery must be installed, before the instrument can be placed back into operation.

If the “ “ symbol appears in the LCD display, you should change the battery as soon as possible. You can continue to take measurements, but reduced measuring accuracy may result.

Replacing the Batteries

The housing base must be removed from the instrument in order to replace the batteries.

➭ Press the tab located beneath connector jacks with a test prod, a banana plug or a similar object in the direction indicated by the arrow as shown on the housing base, and remove the base.

➭ Remove the battery from the battery compartment.

➭ Insert two new 1.5 V mignon cells in accordance with the polarity symbols in the battery compartment.

Place both battery cables between the cells before closing the housing in order to prevent pinching of the cables.

➭ Replace the housing base and press until it snaps audibly into place.

➭ Dispose of the dead battery in an environmentally sound fashion.

15.2 Fuses

The 16 A fuse interrupts the 10 A current measuring range, and the 1.6 A fuse the mA current measuring ranges. All other measuring ranges continue to function.

If a fuse blows, eliminate the cause of the overload before placing the instrument back into operation!

Replacement of Fuses

➭ Open the instrument as described under battery replacement.

➭ Remove the defective fuse with the help of, for example, a test prod, and replace it with a new fuse.

➭ Make certain that the new fuse makes good contact.

The following fuses may be used:

• for current measuring ranges up to 400 mA: type Siba FF(UR) 1.6 A/700 V~ ; 6.3 mm x 32 mm

• for the 10 A measuring range: type Siba FF(UR) 16 A/600 V~ ; 6.3 mm x 32 mm

• Both fuses have a breaking capacity of 50 kA.

24 GMC-I Messtechnik GmbH

Attention!

Be absolutely certain that only the specified fuses are used! The use of a fuse with different triggering characteristics, a different nominal current or a different breaking capacity places the operator, the system and the measuring instrument in danger.

The use of repaired fuses or short-circuiting of the fuse holder is prohibited.

Fuse Testing

➭ Set the selector switch to „ ”.

➭ Plug the measurement cable into the “V, , , F” socket.

➭ Contact the mA socket with the other end of the measurement cable. A continuous audible signal and the display of approx. 10.2

, indicate that the fuse for the mA current range is OK.

➭ Contact the A socket with the other end of the measurement cable. A continuous audible signal and the display of approx.

0.5

, indicate that the fuse for the A current range is OK.

If a value other than those indicated above, or if overflow

(“400.0”; 4 blinks) is displayed, the corresponding fuse must be replaced.

15.3 Housing

No special maintenance is required for the housing. Excessive contamination has an adverse effect on isolation and reduces input resistance. The surface must be kept clean for this reason. Use a slightly dampened cloth for cleaning.

Avoid the use of cleansers, abrasives or solvents.

Device Return and Environmentally Compatible Disposal

The instrument is a category 9 product (monitoring and control instrument) in accordance with ElektroG (German

Electrical and Electronic Device Law). This device is subject to the RoHS directive. Furthermore, we make reference to the fact that the current status in this regard can be accessed on the Internet at www.gossenmetrawatt.com by entering the search term WEEE.

15.4 Recalibration

The respective measuring task and the stress to which your measuring instrument is subjected affect the ageing of the components and may result in deviations from the guaranteed accuracy.

If high measuring accuracy is required and the instrument is frequently used in field applications, combined with transport stress and great temperature fluctuations, we recommend a relatively short calibration interval of 1 year. If your measuring instrument is mainly used in the laboratory and indoors without being exposed to any major climatic or mechanical stress, a calibration interval of 2-3 years is usually sufficient.

During recalibration* in an accredited calibration laboratory

(DIN EN ISO/IEC 17025) the deviations of your instrument in relation to traceable standards are measured and documented. The deviations determined in the process are used for correction of the readings during subsequent application.

We are pleased to perform DAkkS or factory calibrations for you in our calibration laboratory. Please visit our website at www.gossenmetrawatt.com (

 Company  DAkkS Calibration Center or

 FAQs  Calibration questions and answers).

By having your measuring instrument calibrated regularly, you fulfill the requirements of a quality management system per DIN EN ISO 9001.

* Verification of specifications or adjustment services are not part of the calibration. For products from our factory, however, any necessary adjustment is frequently performed and the observance of the relevant specification is confirmed.
