This warning cannot be bypassed, and AC power must be utilized or charging the battery is
necessary.
It is strongly recommended that the batteries be charged for a short time each week, regardless if
the Test Set has been utilized or not. A completely discharged battery will require approximately
16 hours to fully charge. Occasional charges of 16 hours on partially depleted batteries will have
no adverse effects.
The current battery status display is available in the SETUP function.
2.8.1 Auto Shutdown
To preserve battery strength, the TR-220 will automatically shut down after 20 minutes of
inactivity. By toggling any switch during the 20 minutes will reset the timer allowing
extended testing.
Shutdown will not occur when AC power is utilized as the source.
2.9 TR-220 Supplied Antenna
Standard equipment with the TR-220 is a Directional Antenna. The antenna, stored in the case
cover, can either be hand held, tripod mounted, or directly mounted on the Test Set case. The
Test Set also contains a direct connect cable for accurate power and frequency measurements
(± 2 dB) when connected directly to the UUT. The Test Set has a built in 50 dB attenuator to
prevent damage to the Test Set due to the High Power RF associated with Transponders.
2.9.1 Directional Antenna
The Directional Antenna is a printed circuit sandwiched between two opaque Lexan
sheets.
1. Open and remove the TR-220 Test Set case cover. Release the two (2) push button
holders
2. The Directional Antenna can be mounted on the case or be hand-held utilizing the
supplied handle.
2a. To mount the antenna to the case, simply slide the mounting Tabs (located on
the back) into the slots located on the front of the Test Set Case.
2b. To utilize the hand held method, attach the supplied handle to the bottom of the
antenna and hand tighten only.
2c. You may also attach the antenna to a tripod, which will increase the stability due
to high winds or hand movement thus increasing the lock on rate.
3. The operator must first set the proper Antenna Gain value into the Test Set memory.
Turn the Test Set “ON” with the UUT FUNCTION switch in the SETUP position.
