Installation
The CTE701 Verification Tester's 10-position DIP switch
is used to configure its test limits for soft ground, metal
ground, EMI, and operator.
Soft Ground
The soft ground resistance is configured with switches
1-4. Pressing the SOFT GROUND pushbutton will result
in a load with slightly lower resistance than the test limit.

Metal Ground
The metal ground impedance is configured with
switches 5-8. Pressing the HIGH METAL GROUND
pushbutton will load 1 ohm higher than the configured
test limit. Pressing the PASS METAL GROUND
pushbutton will load 1 ohm less than the test limit. For
example, if the monitor to be checked is set to 10 ohms,
the Verification Tester will verify that it passes at 9 ohms
and fails at 11 ohms.

EMI
The EMI high frequency signal is configured with switch
9. The CTE701 Verification Tester provides two different
levels of high frequency signal: elevated and normal.
Pressing the HIGH EMI pushbutton will load a high
signal level within its range. Pressing the LOW EMI
pushbutton will load a low signal within its range.

Wrist Strap
The wrist strap resistance is configured with switch 10.
The CTE701 Verification Tester provides resistance
of a certain value across the wrist strap terminal
input in order to simulate a wrist strap. A good quality
dual-wire wrist cord has a 1 megohm resistor in each
of its conductors. The Verification Tester is designed
to simulate dual-wire wrist straps with and without
resistors. The 12 megohms setting simulates a wrist
strap with two 1 megohm resistors in series.

CONFIGURING THE VERIFICATION TESTER
Configure the Verification Tester's DIP switch to the
settings shown below. This will make its test limits
match the factory default limits of the monitor.
VERIFYING THE OPERATOR CIRCUIT
1. Use the black test lead to connect the Verification
Tester to equipment ground.
2. Power the Verification Tester ON.
3. Use the 3.5 mm mono cable to connect the
Verification Tester to the monitor's operator jack.
The monitor's operator LED will illuminate red, and
its alarm will sound.
