3.6 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.

3.7 Zero : In manual DC 22.000A, 220.00A, 2200.0A and 22000A measurement
modes, the REL 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. In 2-range auto DCA modes for clampmeter (220.00A/2200.0A or
22.000A/220.00A), the system will stay in automatic mode, even if the Zero function is
activated. In other words, it could achieve real automatic operation. In automatic mode,
Zero function could not be entered from higher range, but it could be still activated if
current range is lower one. This is because most residual current value is so small that
