ProtEX-MAX PD8-6060 Explosion-Proof Dual-Input Meter Instruction Manual

F4 Operation

A digital input, F4, is standard on the meter. This digital input is programmed identically to function keys

F1, F2, and F3. The input is triggered with a contact closure to COM, or with an active low signal. During

operation, F4 operates according to the way is has been programmed in the

Advanced Features – User

menu.

Maximum/Minimum Readings

The max & min readings (peak & valley) reached by the process can be displayed either continuously or

momentary:

1. Display briefly by assigning to the F1-F3 function keys or to the digital inputs in the

User

menu.

2. Display continuously by assigning either display to max/min through the

Display

menu.

Any of the F1-F3 function keys (buttons) and the digital inputs can be programmed to reset the max & min

readings. The meters are set at the factory to display the max reading by pressing the Up arrow/F2 button

and to use the Right arrow/F1 button to access the

Reset

menu.

To display max and min channel A reading using function key with factory defaults:

1. Press Up arrow/F2 button to display minimum reading of channel A since the last reset/power-up.

The display will then display the maximum reading of channel A since the last reset/power-up.

2. Press the Up arrow/F2 button again to display the minimum reading of channel A since the last

reset/power up.

3. To reset max/min press Right arrow/F1 button to access the Reset menu. The max & min displays

are reset to actual values.

4. Press Menu to exit max/min display reading.
