Battery And Ac Power Adapter - Testec 220 Instruction Manual

AC/DC Oscilloscope Current Probes TT-CC Series
convention arrow on the probe to get the proper polarity reading.
To increase the measurement sensitivity of the current probes, loop additional
turns of the wire under test through the jaws. See Figure 4. The sensitivity of
the current probe is multiplied times the number of loops in the jaws. For
example: 200 mV/A X 4 turns = 800 mV/A.

7. Battery and AC Power Adapter

Use the information in this section to properly maintain the operation of your
AC/DC Current Probe.
A TT-CC Series current probe uses a single square 9 V battery. As the probe is
a high power product, please use the specified alkaline battery.
As the battery installed is drained, a significant gain error may occur. The
green ON Indicator LED will continue to light until a low battery voltage of 6.5
V is reached.
If probe gain errors are detected, replace the battery with a fresh one.
As an alternative, an AC power converter can be used to avoid gain error due
to poor battery durability. Switch to a square 9V battery only when there is no
AC power supply available.
When using an AC power converter for an extended time, we suggest you
remove the battery from the compartment. Prolonged exposure to extreme
heat can result in battery leakage, and battery electrolyte will damage the
circuit board, thus creating damage to the product. Furthermore, batteries are
high pollution products and therefore by reducing their usage, we will in turn
protect the environment.
