Introduction &Specifications
1-1. INTRODUCTION
1-2. The Model 8600A is acompact and light-weight
digital multimeter (DMM). It features a4!4 digit display,
push-button selection of range and function, auto polarity,
self locating decimal point, self zeroing to eliminate offset
uncertainties, and overload protection for all ranges. Auto-
ranging can be selected when the ac volts, dc volts or kil-
ohms functions are selected. Several options and accessor-
ies for the 8600A are available (see Section 6).
1-3. Push-button controls allow the selection of five ac
and dc voltage ranges, five ac and dc current ranges, and six
resistance ranges. The measurement capabilities of the
8600A range from 10 microvolts to 1199.9 volts ac and dc,
10 nanoamperes to 1.9999 amperes ac and dc, and 10
milliohms to 19.999 megohms.
14. The front-panel readout features a4!4 digit display
using light emitting diodes (LED’s). The display includes a
self locating decimal point and a+or -polarity indicator.
Full-scale readout is 19999 for all ranges and functions except
the 1200 volt ac and dc range, which is 11999. Ablinking
18888 readout indicates that the 8600A is being operated
in an overload condition and provides atest for all seg-
ments in the display.
1-5. Front panel input connectors are banana type and
provide separate connections for current, and volt-ohm
inputs. Both the current and volt-ohm inputs are referenced
to acommon input which is isolated from earth ground and
can operate at apotential of up to ±1000V dc or peak Vac
with reference to earth ground.
1-6. The overload features of the 8600Ainclude afused
current input and an overvoltage protected volt-ohm input.
This protection applies for any function and range selected.
1-7. Several options and accessories are available for use
with the 8600A. The options are listed and described in
Table 1-1 ,and must be specified at time of purchase. The
accessories are listed and described in Table 1-2. Accessories
are compatible with all options and can be ordered at time of

2-13. OPERATING NOTES
2-14. The following paragraphs describe various condi-
tions which should be considered before operating the
8600A.
2-15. Option Information
2-16. Supplementary information is necessary when
operating an 8600A which is equipped with one of the
available options. Detailed information regarding the opera-
tion of each available option is given in Section 6, Options
and Accessories.
2-17. Fuses
2-18. The 8600A is equipped with aline power fuse, and
acurrent overload fuse for the current measuring function.
The line fuse is located near the transformer on the inside of
the instrument. The following procedure should be carried
out only by qualified personnel. To gain access, remove ac
power, remove the retaining screw on the rear of the case
and remove the instrument from the case. When replace-
ment is necessary, use an AGC 1/8A fuse. The current in-
put fuse is located behind the front-panel MA INPUT ter-
minal, and is accessed by turning (ccw) and removing the
MA INPUT terminal. Use aJohn Fluke 376582 replace-
ment fuse or equivalent 2A fast-blo fuse (AGX) 1inch in
length.
2-19. Overrange Indication
2-20. The front panel display, in addition to providing a
measurement reading, is designed to serve as an overrange
indicator. When the full scale capability of the selected
range for any function is exceeded, the display will blink
while indicating a18888 reading. The presence of an
overrange indication does not necessarily mean that the
instrument is being exposed to adamaging input condition.
2-21. Input Overload Protection /j\
CAUTION
Exceeding the maximum input overload conditions
can damage the 8600A.
2-22. Each range and function of the 8600Ais equipped
with input overload protection. The maximum allowable
input overload conditions for each function and range are
given in Table 2-2.
2-23. Autoranging
2-24. Autoranging can be selected when the 8600A is
in the VDC, VAC, or K£2 functions. When the AUTO
pushbutton is depressed the 8600A will select the lowest
range that will display the value of the input signal without
causing an overrange indication. Autoranging stops when one
of the individual range pushbuttons is depressed.
