2.6 Relative + Max/Min + HOLD
Max/Min mode can be nested in REL mode. The meter displays the maximum or
minimum value relative to the reference when Max/Min is pressed in REL mode.
Pressing HOLD under REL + Max/Min makes the meter stop updating the LCD panel.

2.7 Zero : In manual DC 1.1000A, 11.000A, 110.00A, 1100.0A and 11000A
measurement modes, the REL_ZERO pin changes to control Zero function instead of
relative function. In Zero mode, the LCD panel displays DN+K - DN, where DN = 1, 2,
3, … , DN is the last conversion value before Zero is pushed, and DN+K is the current
conversion value. If Zero is pushed again in Zero mode, the meter will refresh the DN
value and displays the DN+K - DN again. The meter returns to normal operation if Zero is
pressed and held for longer than one second. Pressing HOLD in Zero mode makes the
meter stop updating the LCD panel. In Zero mode, LCD will not show any symbol to
remind users of Zero mode is active.
