Condensed Operating Instructions

WARNING
High voltage is applied to the measurement terminals of the 1865 any time the
CAUTION HIGH VOLTAGE LED is ON. While the current from the instrument is
limited, the energy stored in a capacitive device connected to the terminals may be lethal.
Always make sure the high voltage indicator is OFF when connecting or disconnecting
the unknown. A flashing CAUTION HIGH VOLTAGE light and/or DANGER on the
display indicates a defective unit with dangerously high voltages possible at the input
terminals. Power the unit down and do not use.
General Information
The 1865 Megohmmeter/IR Tester is a computer controlled measuring instrument for
direct readout of resistance and current. The voltage applied to the device under test
(DUT) is programmable from 1 to 1000 volts. A pass/fail indicator provides a visual
display of test results based on a preset limit. A set of power-up default test conditions
are stored in the unit and are as set by the factory (1V, test times zero) until
reprogrammed by the user.
Start-up
The 1865 can be operated from a power source between 90V and 250V AC at a power
line frequency of 47 to 63 Hz. The standard 1865 is shipped from the factory with a 2.5A
fuse in place for 115V or 220V operation. To change the fuse refer to paragraph 1.4.3.
Connect the instrument power cord to the source of proper voltage.
IMPORTANT
The interlock connector (included with the unit) needs to be installed on the rear panel
I/O Port connector if the interlock function is not being used.
When the 3.5" Floppy Drive Option is present ALWAYS MAKE SURE NO DISKS
ARE INSTALLED WHEN THE UNIT IS POWERED UP, otherwise information stored
on the disks could be lost.
Press the [POWER] button on the front panel to apply power. To switch power off press
the [POWER] button again or if measurements are to be made proceed with Zeroing the
instrument, discussed in the next paragraph.
