CTE701 Verication Tester
Operation Instructions
Description
The SCS CTE701 Verification Tester is used to perform
periodic test limit verification of the SCS WS Aware
Monitor, Ground Master Monitor, Iron Man® Plus
Monitor, and Ground Man Plus Monitor. Verification
may be accomplished without removing the monitor
from its workstation. The Verification Tester is National
Institute of Standards and Technology (NIST) traceable.
Frequency of verification is based on the critical
nature of the ESD susceptible items handled. SCS
recommends annual calibration of workstation monitors
and the CTE701 Verification Tester. The CTE701
Verification Tester meets ANSI/ESD S20.20 and
Compliance Verification ESD TR53.

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.
Switch
Test Limit 1234
1 gigohm OFF OFF OFF ON
400 megohms OFF OFF ON ON
100 megohms OFF ON ON ON
10 megohms ON ON ON ON
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.
Switch
Test Limit 5678
1 ohm ON ON ON ON
2 ohms OFF ON ON ON
3 ohms ON OFF ON ON
4 ohms OFF OFF ON ON
5 ohms ON ON OFF ON
6 ohms OFF ON OFF ON
7 ohms ON OFF OFF ON
8 ohms OFF OFF OFF ON
9 ohms ON ON ON OFF
10 ohms OFF ON ON OFF
11 ohms ON OFF ON OFF
12 ohms OFF OFF ON OFF
13 ohms ON ON OFF OFF
14 ohms OFF ON OFF OFF
15 ohms ON OFF OFF OFF
16 ohms OFF OFF OFF OFF
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.
Switch
Signal Level 9
Elevated ON
Normal OFF
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.
Switch
Test Limit 10
12 megohms OFF
10 megohms ON
Operation
Iron Man® Plus Workstation Monitor

VERIFYING THE IRON CIRCUIT
Note: A variable DC power supply must be used to
complete this procedure. The CTE701 Verification
Tester cannot verify the iron circuit in the Iron Man®
Plus Workstation Monitor.
15. Turn the voltage alarm trimpot at the back of the
monitor fully clockwise. This configures it to ±5 V.
16. Power the variable DC power supply. Configure it to
5.0 V.
17. Connect the negative terminal from the variable
DC power supply to ground. Connect its positive
terminal to the yellow alligator cord connected to the
monitor's BOARD terminal. The monitor's Iron LED
should illuminate red and its audible alarm should
sound.
18. Set the variable DC power supply to 4.0 V. The
monitor's Iron LED should illuminate green and its
audible alarm should stop.
19. Disconnect the variable DC power supply from the
monitor and ground. Connect its positive terminal
to ground and its negative terminal to the monitor's
yellow alligator cord.
20. Verify that the variable DC power supply is still set
to 4.0 V. The monitor's Iron LED should illuminate
green.
21. Set the variable DC power supply to 5.0 V. The
monitor's Iron LED should illuminate red and its
audible alarm should sound.
