Operation method:
Keystrokes using method and the capacity, power, time reset Settings:
1) Reset button long-press all data
（mAh、Wh、00:00:00）
2) Quickly button twice - capacity Reset （mAh）
3) Quickly button three - power reset（Wh）
4) Quickly button four - time reset（00:00:00）
5) Quickly button five - Set up automatic standby
and Discharge the countdown to remind regularly
6)When no load output no-load, quick seven keys,
and for the current zero to zero in the current
environment temperature for accurate calibration,
so more can do more accurate measurement in
small current.
7)Click the switch interface, in the high voltage
low voltage when backlit parameter Settings,
by double Strike and three strikes for parameter
adjustment, the adjustment process long press
is a continuous fast speed value adjustment.
Key functions:
1) Keep Press long time the key: Zero all data(mAh,Wh,00:00:00)
2) Double-click the key: for the Capacity data reset to zero
3) Three-click the key:for the electric quantity data reset to zero
4) Four-click the key: for the time data reset to zero
5) Five-click the key: Auto-Standby Mode & Timer for discharge alert
6) Single-click to change the window, entering the setup window for
high&Low Voltage background light, adjust the parameters by
double-clicking or three-clicking, click-holding for continuous and
quick adjust.
7) Without load,quickly click the key for 7 times, for current data
reset to zero(0.00A).It is for Precise calibration in local circumstance,
so that the small current could be precisely measured.
8) Keep pressing the key when power-off, then power-on, entering
the Background setup window for High&Low Voltage over-load,
single-click or double-click to adjust the parameters, keep press
the key long time to reset to the default setup
(Note: Please don't calibrate the voltage or current if without
standard instruments)
