the critical value of alarm setting
---Low battery & voltage is displayed. At this time, it not
guarantee the accuracy of the measurements
---Measured current is 8.40A
---Lock the current value displayed
---Store the current value as the data

--- Measured resistance is 30Ω
--- This data is measured in a lot of signals interference
1.Boot up
Boot , DO NOT press the trigger, don't open jaws, nor
clamp any wire
Boot complete, show "OL Ω", then press the trigger,
open jaws, clamp the measured wire
Before booting up, the trigger should be pressed for
a couple of times to ensure the jaws are well closed.
Boot, must maintain clamp meter natural resting
state, don't flip Clamp, don't be imposed outside
force on the jaw, otherwise can not guarantee the
accuracy of measurement
Press POWER Key to Boot, first, automated testing LCD,

Unit does not switch on,batteries are good.
If the ETCR2000+ unit does not switch on despite having good batteries, possible issues include:
- Incorrect battery polarity: Ensure batteries are installed correctly.
- Poor contact of battery contacts: Check and clean or replace the battery contacts.
- Wrong battery type: Use the correct battery type.
- A break in the battery harness: Perform a continuity test; replace the harness if no continuity.
- Displaced POWER button: Re-assemble the button.
- Poor contact of power plug: Re-plug or replace the plug.
- Defective PCB or circuit component: Replace the PCB if current consumption is about 100mA or more at 6V.
