Note) P1: Set value for OUT1 (1) P2: Set value for OUT1 (2)
P3: Set value for failure predictive pressure
P4: Set value for failure predictive count
The failure predictive detection counter is incremented when the
switch is turned on then is turned off, without the pressure (exceed-
ing P1) not reaching the failure predictive pressure (P3).
The failure predictive detection output is energized when the set fail-
ure predictive counter (EC) is incremented consecutively. When the
switch is turned ON and the pressure (exceeding P1) exceeds the
failure predictive pressure (P3), the failure predictive counter is reset.

Peak Hold Mode
Pressing the (UP) button when pressure is dis-
played enables the upper limit peak value (value with a high degree
of vacuum) to be held. n this case, "H" is displayed on the LCD. To
reset holding, press the (UP) button again.
Bottom Hold Mode
Pressing the (DOWN) button when pressure is
displayed enables the lower limit peak value (value with low vacu-
um) to be held. n this case "d" is displayed on the LCD. To return
holding, press the (DOWN) button again.
Reset Function
Pressing the RESET button causes the following:
1) Measurement mode
•Zero adjustment
•Clearing the peak hold mode or bottom hold mode
•Clearing the failure predictive function internal counter
•Resetting the failure predictive output
2) Upon error occurrence
•The data set in the setting mode is retained as is and the state
when the power supply was turned on is restored (System reset
is triggered).
•n case of a data error, the setting mode is selected. When you
finish setting, the state when the power supply was turned on is
restored (System reset is triggered).
Note) n the set value input mode, the reset function does not work.

Replacement of Filter Elements
f filter element clogging causes deterioration of the absorption force or
slows the response time, stop operation and replace the filter element.
Filter Element product number : ZX1-FE
Confirm that the filter gasket is seated in the groove before reassembling
the parts.
Filter Case
•The case is made of polycarbonate. Therefore, do not use it in an
environment that is exposed to chemicals such as thinner, carbon
tetrachloride, chloroform, acetic ester, aniline, cyclohexane,
trichloroethylene, sulfuric acid, lactic acid, or water-soluble cutting
oil (alkalinic).

10. Maintenance
Connector Wiring
Crimping of Lead Wire and Socket
Strip 3.2 to 3.7 mm from the tip of the lead wire and fit a crimp using
the recommended crimping tool. Then insert the core wires carefully
into a socket.
Ensure that the cover of the lead wire does not enter the wire crimp-
ing area (Crimping tool: model no. DXT170-75-1).
Attachment of Socket with Lead Wire
nsert a socket into the square hole in the connector (+, 1, 2, – indi-
cation provided).
Holding by the lead wire, push it all the way in until the hook on the
socket catches and locks in the seat of the connector. (When the lead
wire is pushed in, the hook opens and locks it automatically.) Then
pull the lead wire gently to confirm that it is locked.
Removal of Socket with Lead Wire
To remove a socket from the connector, pull the lead wire out while
pressing in the socket’s hook using a bar with a thin end (approxi-
mately 1 mm). f the socket is to be re-used, open the hook outward.
