General.
Check that the instrument is adjusted to the appropriate power supply
voltage or if an external battery is used that the battery voltage is correct.
It s hould be 6.3 volt s ± 0. 5 volt. If the instrum e nt is not adjusted to the
appropriate mains voltage the necessary adjustment can be carried out by
means of a screwdriver operated switch at the rear of the apparatus. The
battery voltage is checked by switching the PO\VER SWITCH to position
"Batt. Check", whereby the instrument meter pointer should deflect to
within the green area on the scale.
When the POWER SWITCH is set to one of its positions "Line" or "Batt."
the neon lamp (ONI will come on. In the position "Line" it will be on con-
tinuously but in the "Batt." position it will come on with certain regular

will automatically be illuminated. In position "Batt.", on the other hand, it
is necessary to press the push - button marked LIGHT on the front panel if
scale illumination is desired.
