PRODUCT DESCRIPTION
♦【Can Measure High Current Values】Capable of measuring AC/DC up to 600 amps, This clamp adapter is built for higher current measurement.
♦【Large Jaw Size】Maximum Jaw Caliber Size up to 1.57 inches (40mm), allows you to make accurate AC or DC amperage measurement up to 600 amps without breaking the circuit.
♦【High Accuracy】+/- 3.0%+10 accuracy for signal output conversion. The arrow on the Jaw indicates the DC current direction of positive current flow ( from positive to negative).
♦【Multi-compatibility】1mV per ampere output & standard 3/4 inch banana plugs makes it compatible with most multitesters that features with 1mV sensitivity.
♦【Usage】Putting an amp-clamp on a power cord wouldn’t get a reading, you’ll need to put an amp clamp around the live wire only.
SPECIFICATION:
DC Current: 600 A
AC Current: 600 A
Jaw Caliber: 1.77 inch
Output Conversion: 1mV/1A
Conversion Accuracy: +/- 3.0% + 5 digits
Output Impedance: 10K
Dimension: 7.05*3.54*1.42 inch
OPERATION INSTRUCTIONS:
☆ Perfectly work with BTMETER multimeters, such as: BT-770M, BT-770N, BT-770K, BT-90EPD, BT-90EPC, BT-6688G, BT-6688H, etc.
☆ When perform DC current measurement, always press “REL” key on multimeter to zeroes it out.
☆ When perform AC current measurement, always use the clamp go round the live wire only, or use "AC line splitter"
☆ Connect the black banana plug of the BT-605A AC/DC Current Clamp Adapter to "COM" port and the red banana plug to the "µA mA" port.
☆ Press “SELECT” button on the multimeter and press AC/DC button on the Clamp Adapter to choose “DC” or “AC” measurement .
☆ The arrow on the right side of the Jaw indicates the DC current direction of positive current flow (from positive to negative).
7 Days free refund, 15 Days free replace, 365 Days Warranty, Lifetime Tech-support.
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
