[Endian Electric] DC resistance tester correct operation and use

1. Resistance measurement:

After turning on the instrument or pressing the reset button, enter

Initial state (1). Point the cursor pointer to "resistance measurement" and press "OK" to enter state (2) to display the current selection list. The measurement ranges of different current ranges are shown in the table below. You can refer to the selection. The automatic range can reach the entire measurement range listed in the corresponding specifications in the technical specifications. The principle of automatic current selection is to use a larger current. Make the cursor point to the required output current, press "OK" to enter state (3), display the changing charging current and measurement time, #SUPERMAN is the device number, the user can input any modification, MN represents the number of times the device under test, After the charge is completed, the resistance value is displayed automatically. At this time, the “OK” key is pressed once to store the measurement result. The number of measurements MN is incremented by one. Press the "Cancel" or "Reset" key to exit the resistance measurement and enter state (4). The display is discharging. After the discharge is completed, it automatically returns to the initial state (1) to complete a resistance measurement. Megohmmeter, Insulation Resistance Tester is a type of test used to understand and evaluate the insulation performance of electrical equipment. Megohmmeter, Insulation resistance tester is suitable for measuring various motors, cables, transformers, and other electrical equipment.

2. Parameter settings

The parameter setting is the input device number

The input device number helps to distinguish between data and memory data. In the initial state (1), point the cursor at “Parameter Settings” and press “Enter” to enter the state (5), prompt for the new device number, press "" or "" key can make the current input bit from '0' to '9', then cycle from 'A' to 'Z', press "?" key to enter the next one, press "Cancel" key to cancel the current input Bit, until the exit input state, the input character can not exceed 6, after the input is completed, press "OK" key to return to state (5), the new input device number is displayed. After entering the new device number, the measured number of the device under test is automatically set to 1.

3. Memory operation:

In the initial state (1), move the cursor to “View Memory” and press “Enter” to enter state (6). The total number of memory records and operation prompts are displayed. Press “” or “” to enter the state (8) , View the memory records in chronological order. ABC123 indicates the number of the recording device. MN indicates the MN resistance value of the device. Pressing the "" and "" keys at the same time will clear all memory data and press "Cancel" or "Reset" to exit. Memory operation returns status (1). The memory can store up to 250 measurement results. After 250 times, the oldest record will be overwritten. The memory contents can be kept for a long time without loss in the power-off condition.

4. Built-in battery and charging

When the built-in battery voltage is insufficient, the instrument can not display and work normally, and it needs to be charged. It only needs to connect the instrument AC power to 220V AC power, without turning on the instrument power supply, the instrument has a charging instruction, and the indicator light shows red when charging, when the battery When fully charged, the internal charge circuit is automatically turned off and the indicator light is green. For Type 3A instruments, the battery can operate continuously for approximately 2 hours at maximum current after the battery is fully charged.
