P/F
P/F operation prompts the signal testing result (message display and beep)
according to the specified high and low limit parameters and outputs a negative
pulse through the RS232 interface at the rear panel. As shown in the figures below,
the multimeter outputs a negative pulse from the Pin 1 (or Pin 9) if the test
succeeds (or fails).
Press P/F to enter the following interface.
Press High or Low and enter a desired value using the direction keys. Note that the
high limit should always be greater than the low limit and the unit is decided by the
current measurement function. The range of the limit is from -110% to +110% of
the maximum range of the selected measurement function. The settings are
stored in volatile memory and will be cleared automatically at power-off.
After you setting the desired parameters, press ON to enable the P/F operation.
The multimeter automatically exits the P/F setting interface and goes to the
measurement main interface as shown in figure below.
 The status bar displays “P/F”.
 The main display contains the current measurement reading.
 The vice display displays “PASS” if the test succeeds.
