3 Initial Start-Up

Attention!

3.1 Battery test

Four different battery symbols, ranging from fully depleted to fully charged, continuously indicate the momentary charge level in the upper left-hand corner of the display

If battery voltage has fallen below the allowable lower limit, the pictograph shown at the right appears. The instrument does not function if the batteries have been depleted excessively, and no display appears.

3.2 Installing or Replacing Batteries

New batteries must be inserted for initial start-up, or if only one filled segment remains in the battery symbol.

Before opening the battery compartment (see page 5 for location), disconnect the instrument from the measuring circuit (mains) at all poles.

Eight 1.5 V size AA batteries in accordance with IEC LR 6 are required for operation of the insulation measuring instrument. Use new alkaline manganese batteries only.

Rechargeable NiCd or NiMH batteries may also be used. These can only be recharged externally. We recommend rechargeable NiMH batteries.

Always replace batteries in complete sets. Dispose of batteries in an environmentally sound fashion.

Ð Loosen both slotted screws for the battery compartment lid

on the back, and remove the lid.

Ð Remove the battery holder and insert eight 1.5 V size AA bat-

teries with correct polarity in accordance with the symbols.

Make sure that all of the batteries are inserted with correct polarity. If just one battery is inserted with reversed polarity, it will not be recognized by the instrument and may result in leakage from the batteries.

Ð Push the battery holder into the battery compartment such

that the battery holder’s contacts touch the contact springs at the bottom of the battery compartment (see drawing on page 3). If the battery holder is not inserted as specified, the instrument cannot be supplied with power.

Ð Replace the battery compartment lid and retighten the

screws.

The instrument may only be placed into service if the battery compartment lid is securely fastened!

Measuring High-Value Resistance with the KS-C Probe (Option)

When measuring electrostatic discharge capacity for floor coverings, the shielded cable should also be connected to the COM and SHIELD jacks (KS-C accessory set, “cable set consisting of measurement cable and high-resistance measurement cable for measurements in the GΩ range”, see diagram). Be sure to observe color coding.

For measuring with the Test Probe for Remote Triggering (Option Z550A) see section 14.5.1.

4.1 Switching On, Monitoring and Switching Off

If battery voltage falls below the allowable limit value (U < 8 V) the instrument cannot be switched on, or it is immediately switched off.

Measurement cannot be started in the resistance measuring ranges in the event of external voltage.

The instrument only switches itself off automatically after completion of an automatic measuring sequence, and after the predetermined on-time has expired (APOFF parameter in SETUP switch position, see page 12). On-time is reset to its original value as defined in the setup menu, as soon as any key or the rotary function switch is activated.

If the instrument is switched off automatically with the rotary switch in any position other than OFF, it can be reactivated by pressing the stby OFF key.

14 GMC-I Messtechnik GmbH

The instrument can be switched off manually by turning the rotary switch to the OFF position.

5.1 Connection

Checking the Measurement Cables

Before performing insulation measurement, the test probes on the measurement cables should be short-circuited in order to assure that the instrument displays a value very close to 0 Ω (see section 8). This makes it possible to detect interrupted measurement cables, which simulate high insulation resistance. For this instrument, ching from one insulation resistance measuring range to another. When further measurements are performed in the same measuring range, fuse testing is dispensed with for the sake of a faster test procedure.

Ð Connect the device under test to the + and COM jacks. Sample connection layouts for insulation resistance measurement are

included in section 14.1. Insulation resistance can only be measured at voltage-free objects. If mains voltage or external voltage is applied to the measurement inputs, measurement cannot be started. This is indicated by the

high-voltage symbol

5.2 Performing the Measurement

Note: Condensation must be ruled out when performing measure-

ments at close to the freezing point. Ð Select the measuring function and the desired test voltage

5.3 Ending the Measurement

Individual measurement: Measurement is ended automatically as

soon as the measured value has settled in.

Continuous measurement is ended by briefly pressing the ESC key.

In either case, the measured value is retained at the 7-segment display. When discharging begins, the unit of measure for the bar graph changes from Ω to V. The length of the bar graph is continuously reduced as voltage at the device under test drops.

Special Case: Capacitive Devices Under Test

Do not touch the instrument’s terminal contacts during insulation resistance measurements!

If nothing has been connected to the terminal contacts, or if a resistive load component has been connected for measurement, your body would be exposed to a current of approximately 1 mA at a voltage of 1000 V. The resulting electrical shock is not life endangering. However, the noticeable shock may lead to injury (e.g. resulting from a startled reaction etc.).

When an insulation resistance measurement has been performed on a capacitive object it is automatically discharged by the instrument. Contact between the object and the instrument must nevertheless not be interrupted. Do not disconnect until:

•The caution LED (> 50 V) is no longer illuminated

If measurement is performed at a capacitive object such as a long cable, it becomes charged with up to approx. 1000 V (test voltage)! Touching such objects is life endangering!

•The high-voltage symbol is no longer displayed

Three-Phase Systems

All conductors (L1, L2, L3 and N) must be measured

•The analog bar graph has dropped to a value of less than 50 V

against PE!

The instrument’s batteries are exposed to excessive stress during insulation resistance measurement. For this reason it’s advisable to perform individual rather than

continuous measurements.

Measurement Types

You can choose one of two different types of measurement:

• Measuring sequence with automatic polarity reversal (reversal of current flow direction)

• Manual measurement with specified current flow direction

8.1 Measurement with Automatic Polarity Reversal – AUTO Function

Automatic polarity reversal is selected as a default value. MAN does not appear at the display.

Ð Start measurement in both current flow directions by briefly

pressing the START key for one-time polarity reversal or start continuous measurement for permanent polarity reversal by briefly pressing the CONTIN. key.

After the measuring sequence has been started, the instrument performs measurement with automatic polarity reversal, first with current flow in one direction ( until the measured value has settled in. The larger (worst) measured value is displayed.

Difference > 10%

If, during measurement with automatic polarity reversal, the difference between both polarities (current flow directions) are displayed separately (separated by an underscore). ΔRlo>10% appears at the display.

Limit Value Indication

If the measured value is less than or equal to 2 Ω, the Limit LED lights up green. If the measured value is greater than 2 Ω, the LED lights up red. As a prerequisite, the LiLED parameter must be set to “on” (see page 13).

Resistances which do not demonstrate a stable value until after a “settling in period” should not be measured with automatic polarity reversal. Measurement with automatic polarity reversal may

In order to determine whether or not the obtained results are independent of current flow direction, measurement can be performed separately for both directions.

Ð Press the

sired current flow direction: MAN and Ω→ or MAN and ←Ω appear at the display.

Ð Start an individual measurement by briefly pressing the START

key, or initiate continuous measurement by briefly pressing the CONTIN key.

DATA blinks at the display until the measured value has settled in.

Differing results indicate voltage at the device under test (e.g. thermovoltage or unit voltages).

Measurement results can be distorted by parallel connected impedances at load current circuits and by equalizing current, especially in systems which make use of “overcurrent protection devices” (previous neutralization) without an isolated protective conductor. Resistances which change during measurement (e.g. inductance), or a poor contact, can also cause distorted measurements.

Examples of resistances whose values may change during measurement include:

– Incandescent lamp resistance with changing values caused

by warming due to measuring current

– Resistances with a large inductive component In order to assure unambiguous measurement results, causes of

error must be located and eliminated.

Checking the Insulation Measuring Instrument

According to section 5.3.1.2 of VDE 0105-100 (EN 50110-1), the following applies: “These measuring instruments must be tested before, and if applicable after use.” The two outermost jacks on the connection panel must be connected to each other internally via a 10 MΩ test resistor to this end.

The sum of test resistor and cable resistance (for both cables), including test probes, amounts to 10 MΩ ±5%. This value allows for quick self-testing.

The cable resistance R under parameter rLEAd can only be deleted under this parameter by selecting setting CLEAr, see page 11.

12.1 Battery and Rechargeable Battery Operation

When only one filled segment remains in the battery symbol, install a new set of batteries or charge the rechargeable batteries.

Check to make sure that no leakage has occurred at batteries or

28 GMC-I Messtechnik GmbH

rechargeable batteries at short, regular intervals, or after the instrument has been in storage for a lengthy period of time.

Note

Prior to lengthy periods of rest (e. g. holiday), we recom-

Attention!

mend removing the (rechargeable) batteries. This helps to prevent excessive depletion or leakage of batteries, which, under unfavourable circumstances, may cause damage to the instrument.

If leakage has occurred, the electrolyte must be carefully and completely removed with a damp cloth before installing new batteries.

Replacing the Batteries

See section 3.2 and section 12.3.

12.2 Fuses

If a fuse has blown due to overload, a corresponding message error appears at the LCD panel. The instrument’s voltage measuring ranges are nevertheless still functional.

12.2.1 Fuse Link – FUSE Message

This fuse is active in all resistance measuring ranges except for voltage measurement. A replacement fuse is included in the battery compartment (FF315mA/1000V).

Disconnect the instrument from the measuring circuit before opening the battery compartment lid in order to replace the fuse (refer to page 5 for location)!

Checking the Fuse

If a resistance measuring range is selected with the rotary switch with a blown or defective fuse in the instrument, and if the instrument is turned on with the switch in this position, fuse appears at the LCD. Prerequisite: The + and COM measurement jacks are not short circuited.

After eliminating the cause of error and replacing the defective fuse, the fuse message is cleared after the instrument has once again been switched on.

Severe damage to the instrument may occur if incorrect fuses are used. Only original fuses from GMC-I Messtechnik GmbH assure required protection by means of suitable blowing characteristics. Short-circuiting of fuse terminals or the repair of fuses is prohibited! The instrument may be damaged if fuses with incorrect ampere ratings, breaking capacities or blowing characteristics are used!

Replacing the Fuse

Ð Open the battery compartment lid by loosening the two

screws.

Ð Remove the defective fuse and insert a new one. A replace-

ment fuse is included in the battery compartment.

Ð Insert the new fuse. Ð Replace the battery compartment lid and retighten the

screws.

This fuse protects low-resistance (Rlo) and resistance measurements (kΩ) from overloading (electronic hardware circuit).

„EL.Fu“ appears when the fuse blows. Ð Eliminate the cause of overloading. This error message must

be cleared by switching to OFF position.

12.3 Housing

No special maintenance is required for the housing. Keep outside surfaces clean. Use a slightly dampened cloth or a plastic cleaner for cleaning. Avoid the use of cleansers, abrasives or solvents.

Return and Environmentally Sound 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.

We identify our electrical and electronic devices in accordance with WEEE 2012/19/EU and ElektroG using the symbol shown at the right per DIN EN 50419.

These devices may not be disposed of with the trash. Please contact our service department regarding the return of old

devices (see address in section 15). If you use

ries which no longer function properly, they must be duly disposed of in compliance with the applicable national regulations. Batteries or rechargeable batteries may contain harmful substances or heavy metal such as lead (PB), cadmium (CD) or mercury (Hg).

13 Recalibration

The measuring tasks performed with your instrument, and the stressing it’s subjected to, influence aging of its components any may result in deviation from the specified levels of accuracy.

In the case of strict measuring accuracy requirements, as well as in the event of use at construction sites with frequent stress due to transport and considerable temperature fluctuation, we recommend a relatively short calibration interval of once per year. If your instrument is used primarily in the laboratory and indoors without considerable climatic or mechanical stressing, a calibration interval of once every 2 to 3 years is sufficient as a rule.

During recalibration* at an accredited calibration laboratory (DIN EN ISO/IEC 17025), deviations from traceable standards demonstrated by your measuring instrument are documented. Ascertained deviations are used to correct displayed values during later use of the instrument.

We would be happy to perform DAkkS or factory calibration for you at our calibration laboratory. Further information is available at our website:

www.gossenmetrawatt.com (→ Company → DAkkS Calibration Center or → FAQs → Question and Answers Regarding Calibration).

Recalibration of your instrument at regular intervals is essential for the fulfillment of requirements according to quality management systems per DIN EN ISO 9001.

* Examination of the specification, as well as adjustment, are not included in calibra-

tion. However, in the case of our own products, any required adjustment is performed and adherence to the specification is confirmed.
