Safety Precautions - QuadTech 1730T Instruction Manual

The 1730T LCR Meter can provide an external bias output voltage of 5V DC to the device under
test (DUT). Although the 1730T unit is a low voltage instrument, some devices tested
(especially capacitors) can store charge and may cause serious hazards if not discharged
1. Operate the 1730T unit with its chassis connected to earth ground. The instrument 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 that provides earth ground. Serious injury
can result if the 1730T unit is not connected to earth ground.
2. Tightly connect BNC cables to the silver output terminals: H
If this is not done, the DUT's casing can be charged to the high voltage test level and
injury or electrical shock hazards could result if the DUT is touched.
3. Never touch the test leads, test fixture or DUT in any manner (this includes insulation on
all wires and clips) when the bias voltage is applied and the
4. Before turning on the 1730T unit, make sure there is no device (DUT) or fixture
connected to the test leads.
5. When the BIAS
the output terminals.
6. Before touching the test lead wires or output terminals make sure:
a) Make sure any capacitive device has been discharged fully.
b) The BIAS backlight is OFF.
7. In the case of an emergency, turn OFF the POWER switch using a "hot stick" and
disconnect the AC power cord from the wall. Do not touch the 1730T instrument.
8. Be wary when the 1730T instrument is used in remote control mode. The bias voltage
output is being turned on and off with an external signal.
