SCS CTE701 Verification Tester for Continuous Monitors

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. The frequency of verification is based on the critical nature of the ESD-susceptible items handled. SCS recommends the annual calibration of workstation monitors and the CTE701 Verification Tester. The CTE701 Verification Tester meets ANSI/ESD S20.20 and Compliance Verification ESD TR53.

The SCS CTE701 Verification Tester can be used with the following items:

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.

Test Limit

|  | Switch|
---|---|---|---
1| 2| 3| 4
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.

Test Limit

|  | Switch|
---|---|---|---
5| 6| 7| 8
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.

Signal Level

| Switch
---|---
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.

Test Limit

| Switch
---|---
10
12 megohms| OFF
10 megohms| ON

    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.
