How To Use This Manual

Simply click on the "+" or "-" buttons to the left of the chapter titles below to expand that chapter. If you would like to view our video operation manual, click here.

Chapter 1: BASIC OPERATION

The Radiation Alert Charger (fig. 1) is used to zero a variety of quartz or carbon fiber dosimeters. The Charger controls the movement of the hairline fiber inside the dosimeter. When the fiber is on zero, the dosimeter is fully charged/zeroed. It is powered by a piezoelectric generator. The CHARGER requires absolutely no batteries.

To charge a dosimeter you simply squeeze the lever a few times. If the fiber passes zero and is still visible, a discharge button allows the operator to discharge the dosimeter and set it exactly on zero. The clamp is adjustable and self-locking and automatically holds the dosimeter for you. By squeezing the trigger, you can easily position a dosimeter into or remove it from the charger.













Chapter 2: POSITIONING THE DOSIMETER IN THE CHARGER

1. Hold the charger upright as shown in fig. 1. Lift the clamp and pull it back to the approximate length of the dosimeter. Place the dosimeter in the clamp with the recessed end (opposite the lens) over the charging contact. This allows for the electrical contact between the dosimeter and the Charger.

2. While squeezing the trigger and push the clamp against the lens end of the dosimeter and release the trigger. Important: If the clamp is not pushed against the lens end of the dosimeter before releasing the trigger, electrical contact may not be adequate to charge the dosimeter. DO NOT PUSH TOO HARD. You may damage the dosimeter.

3. Check that the position of the dosimeter provides a good view of the scale through the lens. Refer to fig. 2













Chapter 3: CHARGING THE DOSIMETER

4. With the dosimeter locked in place, look through the dosimeter at a light source such as a light bulb, window or a small flashlight to view the scale shown in fig. 3.

5. Squeeze and release the charging lever until you see the fiber appear on the scale. The fiber appears from the right of the scale and moves towards zero. Once you see the fiber, partial squeezes of the charging lever will be enough to control its movement. If the dosimeter is not responding, repeat step 2. If the fiber has traveled to the left of zero but is still visible, push the discharge button until the fiber is on zero. If the fiber is not visible, repeat Step 5.

6. To remove the dosimeter, squeeze the trigger, lift the dosimeter to just above the end of the clamp. Pull dosimeter straight back to disengage it from the charging contact. If your dosimeters are all the same length, you should not have to adjust the clamp as described in steps 1 and 2. The length setting of the clamp will not change unless the clamp is manually adjusted.

NOTE: The ideal operating range for the charger is between 40-60% humidity. If operation occurs outside of these specific conditions, you may notice the fiber move away from zero (discharge) at faster rate. In this case, once the dosimeter is fully charged, remove it immediately from the charger and recheck it to make sure the fiber is on zero.
