LED is ON or flashing. Always make sure the DANGER LED is OFF when connecting
or disconnecting the Device Under Test (DUT).
General Information
The Guardian 6100 Plus Electrical Safety Analyzer is a measuring instrument for direct
readout of Hipot output voltage and leakage current, insulation resistance and ground
bond. The voltage applied to the device under test is adjustable from 50V to 5kVAC and
50V to 6kVDC. The current limit is adjustable from 1µA to 40mA AC in 1µA or 10µA
steps and 0.1µA to 12mA DC in 0.1µA, 1µA or 10µA steps. PASS and FAIL LEDs
provide a visual display of test results based on preset limits.
Start-Up
The Guardian 6100 Plus unit can be operated from a power source between 90 and
250VAC at a power line frequency of 50 or 60Hz. The standard Guardian 6100 Plus
unit is shipped from QuadTech with an 8A fuse in place for AC 90-130V operation. (A
4A fuse is included for 200-250V operation). The G6100 Plus unit is shipped with the
line voltage selector set for 120V. Refer to paragraph 1.4.3 to change a fuse and to
change the line voltage selector.
Connect the Guardian 6100 Plus unit AC power cord to the source of proper voltage. The
Guardian 6100 Plus is designed to be operated with its chassis connected to earth ground.
The Guardian 6100 Plus is shipped with a three prong power cord to provide this
connection to ground. This power cord should only be plugged in to a receptacle which
provides earth ground. Serious injury can result if the Guardian 6100 Plus is not
connected to earth ground.
Press the [POWER] button on the front panel to apply power. To switch the power off
press the [POWER] button again or if measurements are to be made proceed with Test
Parameter Set-Up below. Note: to achieve the specification accuracy, allow the G6100
Plus unit to warm-up for 15 minutes prior to use.
Test Parameter Set-Up
Press the [PROGRAM] function key
Enter the Test Parameters according to your test specification (Table COI-1).
