MAX/UP – The function of this key is dependant on the Current Operating Mode as follows:
PRESSURE MEASUREMENT – If this key is pressed while the pressure is being
displayed, the unit will display the maximum pressure detected since the
capture register was last reset.
SETUP MODE – If this key is pressed in the Setup Mode, the value of the displayed
setting will increment. Pressing and holding this key will cause the rapid
automatic incrementing of the displayed setting.
MIN/DOWN – The function of this key is dependant on the Current Operating Mode as
follows:
PRESSURE MEASUREMENT – If this key is pressed while the pressure is being
displayed, the unit will display the minimum pressure detected since the
capture register was last reset.
SETUP MODE – If this key is pressed in the Setup Mode, the value of the displayed
setting will decrement. Pressing and holding this key will cause the rapid
automatic decrementing of the displayed setting.
ZERO – This function is a combination of two keys (MAX/UP and MIN/DOWN). If both
keys are depressed and held for 5 seconds, the pressure display will be zeroed.
RANGE – The function of this key is to select the desired display engineering units. When
viewing pressure it will sequence through the four ranges (PSI, inH20, cmH20 and mmHg).
BATTERY - If this key is pressed while the pressure is being displayed, the unit will display
the percent (0 to 100) of battery life remaining.
NOTE: If the optional Battery Eliminator is used, the unit will display “Line”.
