Sensor And Probe Installation - ATP ZX-1A Heated Pentode Manuel De L'utilisateur

Once the battery pack is installed, plug the charging unit into a wall outlet and connect the
charger jack to the unit (see Fig 3). When properly connected, the first LED will indicate the
charging status:
- Quickly flashing orange = battery charging
- Slowly flashing green = battery fully charged
- Slowly flashing red = failed batteries, cannot be recharged
New or completely discharged batteries will take approximately two (2) hours to fully re-charge.
When the LED indicates that the batteries are fully charged, the unit is ready for operation.

Sensor and Probe Installation

A new unit comes shipped with the probe not installed on the unit and the sensor packaged in
a hermetically sealed foil bag.
1. Open the bag and remove the sensor.
2. Hold the unit with the front end facing you and note the sensor connection inside the
threaded bushing on the end of the unit. Note that there are five (5) holes corresponding to
the five (5) pins on the sensor – three (3) on the left and two (2) on the right (refer to Fig. 4).
Threaded Bushing
3. Grasp the sensor and align the pins with the corresponding holes. CAUTION: the sensor can
only be inserted one way. When properly aligned, firmly push the sensor into the
connector until it stops.
4. Install the flexible probe by screwing it clock-wise onto the threaded brass bushing around the
sensor until it is finger tight. Note: Do not bend the probe too sharply or the probe can be
damaged.
CAUTION: NEVER operate the unit without the flexible probe properly installed.
Sensor contamination, erratic performance and other problems may occur. Additionally,
the sensor will become quite hot during operation, which could be dangerous.
