which means being charged for more than three hours when the power switch is off.
★
Ensure that the battery is fully charged every three months, and so ensure the
battery life.
★
Screen will go into protection mode if there are four minutes without any
operation when it’s AC power supply, and click anywhere on the screen to exit this
protection.
★
Screen will go into protection mode if there is 1 minute without any operation
when it’s DC power supply, and click anywhere on the screen to exit this protection.
During DC power supply process, it will tweet at any time. With time flying, battery
power will decline, and tweet will thereupon become urgent. When voltage arrived at
10.5V, screen will not be turned on, so please turn off the switch immediately to
charge.
★
Note: When measure with high-voltage mode, the cable fault tester host should
use the battery with it to avoid interfering signals.
★
Directly connecting the instrument to high-voltage is strictly banned, otherwise
it will damage the instrument.
★
If you are using the extension cable or delay instrument to perform test from the
start point of the waveform cursor, then the result should subtract the distance of the
extension cable or delay instrument.
V. Host Operating Procedures
1. Connect "input","output" signal base according to the corresponding test method(If
it’s a fully integrated configuration, simply corresponds to all access required). And
turn on the power switch.
Low-voltage pulse test mode: Connect "input", "output" signal base
Multiple pulse/DC arc extension test mode: Connect "input", "output" signal
