20A/50A/100A Digital Meter DC 6.5-100V Voltmeter Ammeter LCD 4 in 1 DC Voltage Current Power Energy Detector Amperimetro Shunt

PZEM-031: Measuring Range 20A (Built-in Shunt).

PZEM-051: Measuring Range 100A (use external shunt, can matched with 50A, 100A two kinds of shunt).

PZEM-015: Measuring Range 300A (use external shunt, can matched with 50A, 100A, 200A, 300A four kinds of shunt).

NOTE: Before you use the 50A/75mv shunt, please set the range of the meter to 50A(the default setting is 100A)

NOTE
There are many options, the meter or the shunt. please check carefully before order, and choose the one you need.

This meter has to be used with shunt, if you have no shunt at home, please choose the one with shunt

50A/100A DC Voltmeter Ammeter

A.Function
1. electrical parameter measurement function (voltage, current, power, energy).
2. The voltage alarm function (over voltage alarm thresholds, backlighting and voltage flicker tips).
3. The power button clear function.
4. Power-down data storage function.
5. Large-screen LCD screen full display function (display voltage, current, power, energy).
6 Backlight.

B. display and key
I Display Interface
Display voltage, current, power, energy parameters from the large-screen LCD screen simultaneously.
II Display Format
1. Power: measurement range 0 ~ 10kW
1kW display format within 0.0 ~ 999.9W;
From 1kW display format 1000 ~ 9999W.
2. Energy: measurement range 0 ~ 9999kWh
10kWh within the display format 0 ~ 9999Wh;
Above 10kWh display format 10 ~ 9999kWh;
3. Voltage: test range 6.5 ~ 100V
Display Format 6.50 ~ 99.99V
4. Current: Test Range 0 ~ 100A
Display Format 0.00 to 99.99.
III Button
1. The backlight control
By short press the button to turn on or off the backlight, the backlight status automatic storage.
2. The power cleared
Step 1: Press the button until the power area show “CLr” character, then release the button;
Step 2: At this point in the power consumption flashing indicating the current status is cleared, if short press the button again, the consumption data is cleared and cleared quit flashing;
Step 3: If no key is pressed within five seconds, it means that the power does not clear the data and exit cleared.
3. The voltage alarm value
Step 1: Press the button until the power area show “SET” character, then release the button
Step 2: After entering this state, the voltage of the high pressure area shows the current alarm value, the current area displays the current value of low pressure alarm, and the least significant bit starts flashing, then you can press the button through the +1 bit short, when there is no button operation When more than three seconds, the automatic adjustment of the position switch from high pressure to low pressure alarm alarm value has a value, a total of six, the scope voltage alarm threshold set for the 6.5 ~ 99.9V
Step 3: After setting, press the button until the display shows “PASS” character indicates the setting is successful and automatically exit the setting mode.

Note:
Before you use the 50A/75mv shunt, please set the range of the meter to 50A(the default setting is 100A)

Range Selector
Step 1: Press the button until the power area show “Curr” character, then release the button;
Step 2: At this point the current area displays “100 A”, short press button between “100 A” and “50 A” switch, in order to represent the external current range is 100A / 75mV or 50A / 75mV, attention The table can only use these two specifications shunt.
Step 3: Press the button until you exit the setting mode or no key operation is automatically saved after 3 seconds and exit the setting mode.

C. Notes
1. This module is suitable for indoor, not outdoor use.
2. applied load can not exceed the rated voltage and current.
3. The wiring order can not be wrong.
