Resistance Meter

Product Details:

The Desco 19290 Digital Surface Resistance Meter Kit is an instrument designed to measure resistance point-to-point (Rtt) or surface to ground (Rtg). Its test functions include: Resistance measurement accuracy of ±10% (±20% accuracy for 1 x 1012 ohms and greater) Resistance range of <1 x 103 ohms to >1 x 1012 ohms Under load voltages of 10 and 100 volts ±5% Electrification period of approximately 15 seconds The Digital Surface Resistance Meter also measures ambient temperature and relative humidity. Up to 100 measurements may be stored and recalled from the meter's internal memory. This includes the resistance value, temperature, relative humidity and test voltage at the time of the measurement.The Surface Resistance Meter is referenced and designed to be used to make measurements in accordance with the test procedures in

“A Compliance Verification Plan shall be established to ensure the Organization’s fulfillment of the technical requirements of the ESD Control Program Plan. Process monitoring (measurements) shall be conducted in accordance with a Compliance Verification Plan that identifies the technical requirements to be verified, the measurement limits and the frequency at which those verifications shall occur. The Compliance Verification Plan shall document the test methods and equipment used for process monitoring and measurements. If the test methods used by the Organization differ from any of the standards referenced in this document, then there must be a tailoring statement that is documented as part of the ESD Control Program Plan. Compliance verification records shall be established and maintained to provide evidence of conformity to the technical requirements. The test equipment selected shall be capable of making the measurements defined in the Compliance Verification Plan.” (ANSI/ESD S20.20 section 7.3)
Measure Resistance Point-to-Point (Rtt) on the Surface

1. Do not clean the surface.
2. Remove from the surface only those items that might interfere with the test. ESD sensitive devices shall also be removed.
3. Connect both test leads to both 5-pound electrodes, and place the electrodes on the most commonly used area of the surface. Use the 10"electrode spacer to space them 10" apart from each other. The electrodes should also be 2" away from any edge and 3" away from any grounded point. If the most used area is not obvious, use two points near the center of the surface.
4. Push the red pushbutton to perform a measurement. Should the 15-second electrification period appear, it may be bypassed by pushing the red push button
a second time5. Push the right black pushbutton to save the
measurement if desired.
6. Perform additional measurements by placing the electrode on the most commonly used or worn area

Maintenance
The Digital Surface Resistance Meter requires little maintenance. There are no user serviceable parts. If the meter requires service beyond cleaning the electrodes or replacing the batteries, please contact the Desco Customer Service.
 Battery Replacement
Replace the batteries once the battery life indictator is empty.

• Resistance Ranges:1 x 103  to 1 x 106  ohms @ 10 Volts, complies with ANSI/ ESD S4.1
