Overview

Desco 19290 Digital Surface Resistor Meter Kit is a tool used in electrostatic discharge (ESD) testing to measure the resistance of surfaces and materials. The kit typically includes a meter, test leads, and electrodes for measuring surface resistance, volume resistance, and point-to-point resistance. This type of equipment is commonly used in industries such as electronics manufacturing, where ESD can cause damage to sensitive components.

 

Description

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.

A. Test Jacks: The shielded black test lead’s male SMA connector connects into the meter's female SMA connector, and the red test lead’s banana plug connects into the meter's banana jack.

B. Exponent LEDs: These LEDs indicate the surface resistance exponent value. They are color coded for resistance decade quick checks.

C. OLED Display: Displays the temperature, relative humidity, battery life, test voltage and resistance measurement.

D. Power Switch: Slide the switch to the left to power the meter OFF. Slide the switch to the right to power the meter ON.

E. Black Pushbuttons: Each black pushbutton corresponds to the prompts on the bottom-left and bottom-right of the display. These buttons are used to access the Settings and Memory Recall menus and scroll up and down between menu options.

F. Red Pushbutton: Corresponds to the prompts located in the bottom-center of the display. This button is used to perform tests and select menu options. Press and hold this button when in the Settings and Memory Recall menus to exit and return to the home screen.

G. Battery Compartment: Open this compartment to install the four AA alkaline batteries needed to power the meter. Replace the batteries once the battery icon on the display is empty.

 

Operation

General Guidelines

Use both 5-pound electrodes for Resistance Point-to-Point (Rtt) measurements.

Use one 5-pound electrode, and connect the black test lead to ground for Resistance-to-Ground (Rtg) measurements.

Ensure that the item being measured is electrically isolated (placed on an insulative surface). The meter will measure the lowest resistance path.

Minimize crossing the test leads when possible.

 

When using 5-pound electrodes:

Place them no closer than 2" from the edge of the surface being measured.

Place them no closer than 3" to any groundable point.

Place them about 10" apart from each other for Rtt measurements of a worksurface.

Place them about 3' apart from each other for Rtt measurement of a floor.

 

Preferable electrode placements include:

Most commonly used area of a surface

Most worn area

Center of surface

Furthest area from a grounded point
