PRODUKTBESCHREIBUNG
♦ 【Kann hohe Stromwerte messen】 Kann AC/DC bis zu 600 Ampere messen. Dieser Zangenadapter ist für die Messung höherer Stromstärken ausgelegt.
♦【Große Backengröße】Maximale Backenkalibergröße bis zu 1,57 Zoll (40 mm), ermöglicht Ihnen eine genaue AC- oder DC-Stromstärkemessung bis zu 600 Ampere, ohne den Stromkreis zu unterbrechen.
♦【Hohe Genauigkeit】+/- 3,0 %+10 Genauigkeit für die Signalausgangsumwandlung. Der Pfeil auf der Backe zeigt die Gleichstromrichtung des positiven Stromflusses an (von positiv nach negativ).
♦ 【Multikompatibilität】 1 mV pro Ampere-Ausgang und standardmäßige 3/4-Zoll-Bananenstecker machen es mit den meisten Multitestern kompatibel, die über eine Empfindlichkeit von 1 mV verfügen.
♦【Verwendung】Das Anbringen einer Verstärkerklemme an einem Netzkabel würde keinen Messwert liefern, Sie müssen eine Verstärkerklemme nur um das stromführende Kabel anbringen.
SPEZIFIKATION:
Gleichstrom: 600 A
Wechselstrom: 600 A
Backenkaliber: 1,77 Zoll
Ausgangskonvertierung: 1 mV/1 A
Konvertierungsgenauigkeit: +/- 3,0 % + 5 Ziffern
Ausgangsimpedanz: 10K
Abmessungen: 7,05 * 3,54 * 1,42 Zoll
BEDIENUNGSANLEITUNGEN:
☆ Funktioniert perfekt mit BTMETER-Multimetern wie: BT-770M, BT-770N, BT-770K, BT-90EPD, BT-90EPC, BT-6688G, BT-6688H usw.
☆ Wenn Sie eine Gleichstrommessung durchführen, drücken Sie immer die Taste „REL“ am Multimeter, um den Wert auf Null zu setzen.
☆ Wenn Sie Wechselstrommessungen durchführen, verwenden Sie die Zange immer nur um das stromführende Kabel herum oder verwenden Sie einen „AC-Leitungssplitter“.
☆ Verbinden Sie den schwarzen Bananenstecker des BT-605A AC/DC-Stromzangenadapters mit dem „COM“-Anschluss und den roten Bananenstecker mit dem „µA mA“-Anschluss.
☆ Drücken Sie die „SELECT“-Taste am Multimeter und die AC/DC-Taste am Zangenadapter, um „DC“- oder „AC“-Messung auszuwählen.
☆ Der Pfeil auf der rechten Seite der Backe zeigt die Gleichstromrichtung des positiven Stromflusses an (von positiv nach negativ).

Customer Reviews
But the instructions are wrong. It must be connected in the multimeter to mV scale, not to mA scale.
I evaluated this clamp meter at my lab for DC currents only. All measurements were taken
at 10 amps or less.
Comments:
In the past twenty years, "safety shrouded" test leads have become the norm.
This is understandable in AC or DC volts or in any circuit with high voltage potentials.
In this particular application, the safety shrouded leads are not necessary, and make it
difficult to connect to older multimeters.
Why are they not needed? You are not opening the circuit to take a current measurement,
and the clamp output is only 1mv/AMP . So in the worse case scenario if you were measuring 600 AMPS
(the maximum current the device can handle) the output from the clamp will be 600mv only!
Second comment:
The manual enclosed was for the wrong model!
It tells you to set meter to microamp function, this is wrong!
Set dvm to DC millivolt range (which one depends on how much current you expect)
comment 3:
They tell you to press "REL" key on dvm, don't do this unless you are measuring small currents (< 2.5 A)
My offset reading was -0.133 Amps (with zero current input)
If you press "REL" you will add 0.133 AMPS (in my case) to all readings, it will ONLY help you for small
currents. For larger currents, it will make the readings worse.
Most please that buy a clamp meter, do so to measure large currents, that is probably for situation.
So, do NOT press the "REL" key
comment 4:
Great value for the money, errors were less than 4.5% if you keep it between 3A and 10A
No measurements were taken above 10A, I will leave that to someone else to do, my lab
is very limited. (NO AC measurements were taken also)
I don't see how I can do better than this, considering how little money I payed!!
Easy to use
I got this for its ability to measure DC current. I already have an AC clamp meter. This discussion is only about DC current measurment. I woud guess that most negative reviewers didn't understand how to use it and the instructions are terrible. AC clamp meters use current transformers. DC uses Hall effect sensors. Wikipedia explains both of these. To use DC current, do the following. Get a good quality voltmeter capable of sesolution to 0.1 millivolts. I have an Amprobe meter. place the meter in dc volts, millivolt range. Turn on this device in DC mode and orient it in the same direction that it will be in when clamped around the wire. In my case I got a reading of negative 1.4 mV without a wire flowing through it. If you read about Hall effect sensors, you will understand why. Then I placed it around the negative battery terminal wire . Then I gor a reading of positive 0.5 mV. The difference is 1.9 mV indicating a current of 1.9A flowing through the wire. The ratio is 1 mV eqal 1 amp. If I flip it around, I would get negative 3.3 mV. The difference would still be 1.9 mV in the other direction. I hope this helps you.
good stuff
