Product Description
Attention:
1.Include a current transformer, no need to buy it
separately.
2.Please try not to install the meter and current transformer around the high temperature, strong magnetic field
and large transformer, otherwise the accuracy will be affected.
3.In order to obtain a higher precision measurement, it is recommended to "preheat for 5 minutes" before
adjusting the calibration.
4.Since the 24V battery charge full of floating voltage may be over 30V, so "no" recommended direct use it.
5.
When you select range, not the larger the better. the larger the range, the larger the error, it is recommended
that it is 1.5 or 2 times as large as the actual test value.
6.This meter and CT have been calibrated by the "one to one". Please don't mix it up when you use it in the later
period. If mixed, you need to recalibrate it.
Product Features:
The wide power supply range, with reverse polarity protection.
Display voltage and current on the screen at the same time.
Use the SMT technology, so consistency is very good.
With a voltage calibration potentiometer, current calibration potentiometer, you can calibrate by yourself. The tolerance is absolutely exit.
CT adopts the design of perforation type wire through the hole, without having to cut wires, without damage, without changing the original electric current wire can be achieved current measurements.
Since CT and measured wire is isolated completely, this meter can be measured the current of the power positive, negative and any devices, don't need to worry about the ammeter "common ground".
The positive and backward current can be measured, and the "positive" current is shown in the positive direction (the decimal point is always bright or not bright), and the "negative" current is shown in the reverse direction (the decimal point flashes slowly.
It can be tested two "completely isolated" devices. The voltage of A device, and the current of the B device. Or the voltage of device B, the current of A device.
The withstand voltage value up to 2KV between the tested conductor.
High reliability, high resistance to current shock, no current impact damage ammeter.
With three wires, connection is convenient, easy connect to solar system/car/electric vehicle/motorcycle interior wires. It is used to monitor the battery voltage and can be also used for other products.
Calibration Method:
The relative error between the instrument and the instrument, or after long-term use, due to component aging or environmental temperature changes caused by the error can be calibrated by the following methods, in order to get more accurate measurements, it is recommended to energize and then preheat more than 5 minutes before recalibration.
Current calibration:
In the condition of without current, use a screwdriver to adjust the "zero(or 0)" potentiometer that behind the transformer until the decimal point of the ammeter flashes fast to the best;  always bright or no light shows positive current, slow flashing shows negative current
In the condition of the half of actual measured current value, adjust the "amplitude modulation (or A)" potentiometer by the side of the transformer until it is consistent with the standard meter.
If the test accuracy is very high, you can repeat the above two steps to get higher accuracy.
Voltage calibration:
In the condition of the half of actual measured voltage value, adjust the voltage calibration potentiometer of the meter with the screwdriver until it is consistent with the standard meter.
Working conditions:
Operating temperature: -10 ~ +50 ℃
Working humidity: 10 ~ 80% (no condensation)
Working pressure: 80 ~ 106kPa
Sun exposure: no direct exposure
