PREPARATION

ALKALINE BATTERY POWERED MODEL

1. Depress the locking tab on the front of the battery compartment cover with a coin or at object and pull the battery sleeve handle away from the top of the instrument.

2. Place three (3) approved batteries into the battery compartment. BE SURE TO OBSERVE AND FOLLOW THE POLARITY MARKING on the inside of the battery holder for proper battery installation. The instrument will not function with improperly installed batteries.

3. Replace the battery compartment cover pushing it in place until the locking tab snaps into position. Check to be sure the battery compartment cover is secure to the instrument body by rmly pulling the handle away. The handle will remain in place if cover is properly in place.

PREPARATION

LiON RECHARGEABLE BATTERY MODEL

For safety during shipping, the TKX with LiON rechargeable battery has been packaged with a special label covering the ON/OFF Switch to insure the device does not turn on during shipment. This label must be removed before the TKX can be powered on.

Follow the procedure in the section titled “Battery Charging” (page 14) to perform an initial charge to the battery.

10

OPERATION AND USE

1. Turn the unit on in an uncontaminated / gas free environment by moving the switch from the “OFF” to the “ON” position.

2. The green ready LED will illuminate if there is ample battery power. The red LED may icker and the tick may sound during the warm up. To silence the tick, rotate the tick wheel fully counterclockwise.

3. Adjust the “TICK ADJUST” by rotating it in a clockwise direction until a uniform tick begins to sound. A uniform tick rate indicates a fully warmed up instrument. The red LED will ash at the same time the tick sounds.

4. Approach suspected leak areas with the sensor until the tick begins to increase. When the tick increases do not move the sensor from the suspected leak area, rotate the tick adjust slightly counterclockwise to slow the ticking sound and continue to approach the leak. Continue to use this method to pinpoint the leak.

REMEMBER: An increase in tick indicates you are approaching a leak, a decrease in tick indicates you are moving away.

11

OPERATION AND USE

5. If the green LED does not illuminate or blinks, the alkaline batteries must be replaced or the rechargeable battery must be recharged.

6. If the instrument does not perform or it has been damaged, test the instrument by following the “operation check” procedure in this manual.

12

BATTERIES

Battery Replacement Alkaline Battery Powered Devices

If the green LED fails to illuminate, the batteries need replacement.

1. Depress the locking tab on the front of the battery compartment cover with a coin or at object and pull the battery sleeve handle away from the top of the instrument.

2. Removed the spent batteries and place three (3) approved batteries into the battery compartment. BE SURE TO OBSERVE AND FOLLOW THE POLARITY MARKING on the inside of the battery holder for proper battery installation. The instrument will not function with improperly installed batteries.

⚠ Warning: To prevent the risk of ignition of ammable atmospheres, batteries must only be changed in an area known to be non-hazardous.

3. Replace the battery compartment cover pushing it in place until the locking tab snaps into position. Check to be sure the battery compartment cover is secure to the instrument body by rmly pulling the handle away. The handle will remain in place if cover is properly in place.

A fresh set of alkaline batteries should operate the instrument for approximately 30 hours.

BATTERIES

Battery Charging LiON Rechargeable Battery Powered Devices

If the green LED next to the ON/OFF switch blinks or fails to illuminate on the instrument, the battery needs recharging.

Recharge the battery only at a temperature between 32 and 104 ºF (0 – 40 ºC)

1. Remove the Charging Port Cover. (Note: this cover is tethered to the TKX housing. Care should be taken not to pull the end of the tether completely out of the Charging Port Hole.)

2. The charging connection should be visible through the charging port hole. Insert the plug from the approved battery charger that was provided with your TKX instrument.

3. The charging LED will illuminate red to indicate that the battery is charging and green to indicate a fully charged battery. Charging may take up to 6 hours.

4. When charging is complete, remove the charger plug and replace the charging port cover. The instrument will operate for approximately 20 hours continuously on a full charge.

15

OPERATION CHECK

First follow steps 1, 2 and 3 (page 10) in the Operation and Use section. Then expose the sensor to a known gas source such as an unlit butane lighter. The tick should increase when the gas is applied. The tick will decrease when the gas is removed.

If the unit fails to respond, the sensor may need replacing or the unit may need to be sent in for repair (see below).

⚠ CAUTION This instrument shall only be

repaired by a SENSIT factory authorized repair technician.

16

SENSOR REPLACEMENT

1. Turn the unit off

2. Pull off the sensor cap

3. Unplug the old sensor and discard

4. Line up reference tab on side of sensor with

reference mark on sensor circuit board and

plug in sensor

5. Replace sensor cap

6. Turn on unit and perform “Operation Check”
