CTPH -Setting Up the Recorder

SETTING UP THE RECORDER
Now that you have learned about the different parts of the recorder, you can set it up.
Determine whether you want the recorder wall mounted or sitting on a bench top.

Placing the Recorder on the Bench Top

Figure 2-1 shows the removal of the decorative foot cover.
1. Place the recorder on its back (so it is face up).
2. Remove the clip-on foot cover by lifting up on the cover and releasing it from the stabilizing arm at the bottom of the recorder. This exposes the rubber feet and stabilizing arm. The rubber feet protect the bench top surface.

CAUTION: DO NOT ATTEMPT TO SET THE RECORDER UPRIGHT ON THE BENCH WHEN THE CLIP-ON FOOT COVER IS IN PLACE. THE RECORDER WILL TOPPLE OVER.

3. Swing out the stabilizing arm and extend it towards you. Figure 2-2 shows how to swing out the stabilizing arm. Make sure the slot in the stabilizing arm extends out the rear of the recorder. HUMIDITY pH ░C

Swiveling Stabilizing Arm

NOTE: When the recorder is in normal operating position (the door is closed and the control panel door is closed), the stabilizing arm should be pushed to middle position (the bumps on the arm will click in place under the recorder). Refer to Figure 2-3a. Note that the arm extends towards the front or rear of the case. If the unit is placed on a bench top snug against the wall, extend the stabilizing arm fully to the front of the unit. Refer to Figure 2-3b.

Mounting the Recorder on the Wall
To mount the recorder on the wall, first locate the wall mounting holes using the template provided in the wall mounting kit. Leave the decorative foot cover (Figure 1-1, item #18) in place*. After drilling the holes, insert the wall anchors and put in the screws, leaving 1 ┌8 inch (3 mm) between the screw heads and the wall. Hang the recorder by positioning the two (2) ôkeyholesö in the rear cover over the screw heads.

NOTE: The ac adaptor has a 6 foot (2 meter) cable.

* If the decorative foot cover is not in place, go through the following steps to reinstall the cover (if desired):
1. Place the recorder on the table (so it is front face up).
2. Roughly position the foot cover so the clips are in line with the stabilizing arm. Gently ôstretchö the clips out and position over the arm as shown in Figure 2-4a.
3. Once the clips are in place, gently slide down until the foot cover is even with the front of the recorder as shown in Figure 2-4b.

Using Batteries
The recorder operates on either four ôDö size batteries or on ac power. 110Vac and 220Vac adaptors are available.

NOTE: In the event of ac power failure, the unit will switch over to battery power automatically. Keep a fresh set of batteries in the unit in case of power outage, when it can be especially important to have a record of pH and fluid temperature.

Installing Batteries
You may power the recorder with four ôDö size batteries. For adequate performance and battery life, use alkaline batteries. The recorder operates full time on battery power alone for up to one month when using fresh alkaline batteries. When replacing batteries, we recommend that you use Duracell MN1300 ôDö size batteries for long life and for best performance at low temperatures.

To install the batteries

Figure 2-5. Battery Compartment and Battery Orientation
1. Open the control panel door.
2. Turn the power switch to ôOö position.
3. Place the recorder on a soft surface front face down. Locate the battery compartment at the bottom.
4. Open the battery compartment door by pressing down firmly on the tabs located along the top edge.
5. Remove the battery door. 6. Install the batteries, oriented as shown in Figure 2-5, in the battery compartment.
7. To replace the battery door, first place the bottom edge of the door into the positioning slots in the compartment.
8. Push down on the door to snap the tabs in place.

The recorder continuously monitors the battery voltage. A ôLO BATö indication in the upper left-hand corner of the main LCD (refer to Figure 2-6) indicates that only one to two weeks of reliable battery operation remain, and that the batteries need replacing within this time frame. Also, if the unit is operating under battery power and the battery voltage is too low to permit reliable operation, the system shuts down and displays ô---ö in the LCD. The system may be restarted by changing the batteries or by the re-initiation of ac power. If ac power fails, the circuitry will attempt to automatically switch to battery backup. If viable battery power is available, the system will operate on battery power until the batteries fail or ac power returns. When ac power returns, the recorder will automatically reset itself (refer to Section 8.5).

Connecting AC Power
The recorder can be ac powered using the 9Vdc, 1Amp ac adaptor supplied. The ac power jack is located on the right side of the unit (refer to Figure 1-1, item #6.). Make sure the power switch on the control panel (refer to Figure 1-1, item #7) is in the ôOö position when plugging in the ac adaptor. The adaptor cable is 6 feet (2 meters) long.
