cover by removing the two cross head screws holding it in place.
The batteries must be inserted in the correct orientation, as
indicated by the drawing within the battery compartment. Incorrect
insertion of batteries will not allow the unit to operate. Replace the
battery cover and insert the screws. If the battery voltage falls too
low, a low battery warning symbol will be displayed at the top left
hand cell of the display in normal operating mode. A low battery
warning will also be displayed during a result display. Test results
may be inconsistent under these conditions.
3. battery eliminator
An external battery eliminator is available for prolonged use of the
B & K Model 570A.
Some ICs consume a significant amount of
current when powered up, and battery life can be conserved by
using the eliminator. There is no need to remove the batteries prior
to inserting the battery eliminator. However, please note that during
prolonged periods of non-use batteries are prone to leakage and
should be removed.
Note that to avoid damage to the unit we
strongly advise that you only use the recommended battery
eliminator that is available by contacting your distributor. Note that
using an incorrect battery eliminator voltage may damage the unit
and invalidate the warranty.
4. switching on
To switch the unit on, simply press the 'ON' key. To preserve battery
life, the unit powers itself off after approximately three minutes of
non-use or when “Sw Off” is selected from the main menu. When
the unit is switched on, it first performs a self-diagnosis test.
Therefore, before switching on, check that the test socket is empty to
prevent interference with the diagnostics. If the unit passes the self-
test, a pass result will be displayed on the screen. Press a key to
enter the main operating mode - the display will be as follows:
