Safety Instructions

Observe this documentation, in particular all included safety informa-tion, in order to protect yourself and others from injury, and to prevent damage to the instrument.

Carefully and completely read and adhere to these condensed operating instructions, as well as the instrument’s operating instruc-tions.
The documents can be found at http://www.gossenmetrawatt.com. Retain these documents for future reference.
Tests/measurements may only be performed by a qualified electri-cian, or under the supervision and direction of a qualified electrician. The user must be instructed by a qualified electrician concerning performance and evaluation of the tests/measurements.
The multimeter may only be operated by persons who are capable of recognizing touch hazards and taking the appropriate safety pre-cautions. Touch hazards in accordance with the standard exist any-where, where dangerous voltages may occur. Avoid working alone when taking measurements which involve touch hazards. Be certain that a second person is present.
Observe and comply with all safety regulations which are applicable for your work environment.
Wear suitable and appropriate personal protective equipment (PPE) whenever working with the device.
Use only the specified accessories (included in the scope of delivery or listed as an option) with the instrument.
Carefully and completely read and adhere to the product documen-tation for optional accessories. Retain these documents for future reference.
Use the instrument in undamaged condition only.
Inspect the device before use. Pay particular attention to damage, interrupted insulation or kinked cables.
Damaged components must be replaced immediately.
Accessories and cables may only be used as long as they’re fully intact.
Inspect accessories and all cables and before use. Pay particular attention to damage, interrupted insulation or kinked cables.
If the instrument or its accessories don’t function flawlessly, perma-nently remove the instrument/accessories from operation and secure them against inadvertent use.
If the instrument or accessories are damaged during use, for exam-ple if they’re dropped, permanently remove the instrument/accesso-ries from operation and secure them against inadvertent use.
Do not use the instrument and its accessories after long periods of storage under unfavorable conditions (e.g. humidity, dust or extreme temperature).
Do not use the device and its accessories after extraordinary stress-ing due to transport.
Only use the instrument and its accessories within the limits of the specified technical data and conditions (ambient conditions, IP pro-tection code, measuring category etc.).
Do not use the device in potentially explosive atmospheres.
The device must not be exposed to direct sunlight.
The device and the accessories may only be used for the
tests/measurements described in the documentation for the device.
Maximum allowable voltage between the voltage measuring sock-ets or all connector sockets and ground is 1000 V for measuring category III and 600 V for measuring category IV.
The multimeter may only be operated with installed rechargeable battery pack or mains module. Dangerous currents and voltages are otherwise not indicated! In addition, the device may be damaged.
Weak (insufficiently charged) rechargeable battery: Do not perform safety-relevant measurements if the “weak battery” icon appears in the battery level indicator. Furthermore, compliance with the listed specifications is no longer assured.
Be prepared for the occurrence of unexpected voltages at devices under test (e.g. defective devices). For example, capacitors may be dangerously charged.
Do not perform any measurements in electrical circuits with corona discharge (high-voltage).
Dangerous pulsating voltages in HF electrical circuits. Be careful, if you perform measurements in them.
Do not use the device if the fuse cover has been removed. Touch contact with dangerous voltage is otherwise possible.
The device is equipped with fuses. The device may only be used as long as the fuses are in flawless condition. Defective fuses must be replaced.
Plugging in the measurement cables must not necessitate any undue force.
Never touch conductive ends (e.g. of test probes).
Fully unreel all measurement cables before starting a test/measure-ment. Never perform a test/measurement with the measurement cable rolled up.
Ensure that alligator clips, test probes or Kelvin probes make good contact.
The instrument is equipped with a Bluetooth® module. Determine whether or not use of the implemented frequency band of 2.402 to 2.480 GHz is permissible in your country.
Always create a backup copy of your measurement data.

Battery Module

The test instrument is powered by a rechargeable battery module. Therefore, observe the following:

Carefully and completely read and adhere to the “Safety Informa-tion Supplement” for the rechargeable battery module Z270A or Z270G (3-349-997-15 or 3-447-030-51).
The manufacturer’s safety data sheet is included in the supple-ment. Read and adhere to this safety data sheet as well.
The battery module must not be exposed to direct sunlight (neither inside nor outside of the device).
Only charge the battery module within temperatures of 10 … 45 °C.
Only store the battery module within temperatures of –20 … 50 °C.
Only charge the battery module within temperatures of –10 … 50 °C.
Danger of excessive depletion: In some cases, a deeply depleted battery module cannot be recharged (immediate failure) and must be replaced. Its service life might also be reduced.
In order to prevent the battery module from becoming fully depleted, you must recharge it least once a year, but preferably at more frequent, regular intervals.
Battery module transport:
Read the “Safety Information Supplement” for the rechargeable battery module Z270A or Z270G (3-349-997-15 or 3-447-030-51)!

Applications

Please read this important information!Intended Use / Use for Intended Purpose

The METRAHIT IM XTRA BT is a multimeter and milliohmmeter, insula-tion measuring instrument, coil tester, and data logger. The METRA-HIT IM E-DRIVE BT is a multimeter, milliohmmeter, insulation measur-ing instrument, coil tester and data logger for hybrid and electric drives. The METRAHIT IM TECH BT is a multimeter and milliohmme-ter, and data logger.
They are portable devices which can be held in the hand during the performance of measurements. With them the measurements described in these short-form operating instructions and those described in the operating instructions can be performed. Description of included features: “Features” on p. 5.
The multimeter is equipped with an automatic socket blocking mecha-nism for your safety, and in order to safeguard your instrument. This mechanism is linked to the rotary switch and only allows access to those jacks which are required for the selected function. It also pre-vents turning the rotary switch to impermissible functions when mea-surement cables are plugged in.
Safety of the operator, as well as that of the instrument, is only assured when it’s used for its intended purpose.

Use for Other than Intended Purpose

Using the instrument for any purposes other than those described in the condensed operating instructions or these instrument operating instructions is contrary to use for intended purpose.
