Battery Installation - Testec 220 Instruction Manual

AC/DC Oscilloscope Current Probes TT-CC Series
The TT-CC series' current probes have in their design a priority external power
circuit. Therefore it is safe to simultaneously install the battery and the
external power supply. During usage, removing the external power supply will
not produce waveform anomaly or any damage. However when external power
is used for an extended time (more than 1 week), removal of battery is
recommended. This will avoid leakage of battery since the quality of the
batteries is something that is out of our control.

7.1 Battery Installation

1. Remove the probe from the circuit.
2. Open the battery compartment by loosening and removing the three
screws on the back of the probe. Lift off the back cover.
3. Observing polarity, attach the new alkaline battery to the connector
buttons and place the battery into the compartment, as illustrated in
Figure 5.
4. Replace the back cover and lightly tighten the three cover screws.
