Digital Surface Resistance Meter Kit

Installation, Operation and Maintenance

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 10

12

 ohms and greater)

•  Resistance range of <1 x 10

3

 ohms to >1 x 10

12

 

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.

October 2018

The Surface Resistance Meter Kit (or its Meter) is referenced 

and designed to be used to make measurements in 

accordance with the test procedures in: 
•  Working surfaces, storage racks, trolleys and seating - 

IEC 61340-2-3 

•  Flooring - IEC 61340-4-1 
•  Garments - ANSI/ESD STM2.1 Garments 
•  Person/footwear / flooring system - IEC 61340-4-5

“A compliance verification plan shall be established to 

ensure the organization’s fulfilment of the requirements 

of the 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 

used for process monitoring and measurements. If the 

organization uses different test methods to replace 

those of this standard, the organization shall be able 

to show that the results achieved correlate with the 

referenced standards. Where test methods are devised 

for testing items not covered in this standard, these shall 

be adequately documented including corresponding 

test limits. 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.” (EN 61340-5-1 clause 5.2.4 Compliance 

verification plan)
