The AXD530 Keypad
The internal clock rate of the AXD530 software
may cause the meter to react slowly to a key push.
The reaction time of a key push will vary with
different functions (1–3 seconds). Maintain pressure
on the desired key until you see the required response
on the display.
Key Functions:
ON/OFF
This key is used to turn the instrument
on or off.
ZERO
The AXD530 will zero the instrument
any time this key is pushed. To get a
proper zero, make sure no pressure
difference is applied across the ports
and no kinks are in the hoses.
