The mantissa field is a5-1/2 digit LED display
complete with polarity indicator and afloating
decimal point. Measurement data and other
operator data is displayed in the mantissa field.
The exponent field is atwo digit LED display plus a
negative sign. It is used for displaying error codes,
limit results (H, L, P), and exponents of 10.
Exponents are used for entering, storing, and
recalling data. It is not used to display basic
measurement data.
Measurement units of the selected measurement
function are defined by the annunciators. They
include: V, mV, O, kQ, and MQ.
The POWER switch is apush-push switch used to
turn the 8860A on and off.
Lights to indicate that the 8860A is in the remote
operating mode. When the light is off, the 8860A is in
•the local mode.
All 8860A measurement, control, and data functions
are governed by these multi-function push-button
switches. The switches are divided into functional
groups. They are:
