KEYSIGHT is a German B2985A insulation material volume resistivity testMeasurement Preface
Keysight B2985A and B2987A electrostatic meters/high resistance meters simplify the characterization of surface resistivity and volume resistivity of insulation materials by providing information on the changes in resistance or current over time on the front panel.
You can use the Keysight 16008B resistance box to measure the surface resistivity or volume resistivity of thin films or sheet materials, and also use customized resistivity measurement fixtures to measure samples of other shapes.
Keysight B2985A and B2987A electrostatic meters/high resistance meters have a current measurement resolution of 10aA (0.01fA) and can measure 10P Ω (10 to the 16th power Ω) resistance using the built-in 1000V voltage source.
According to ASTM D257 standard (unless otherwise specified), insulation and surface resistance are usually measured after applying a test voltage (live) for 60 seconds, so it is important to be able to measure the changes in these parameters over time.
B2985A and B2987A provide timer triggering and operation functions, which can calculate measurement data at specified times to obtain resistivity data at different points. Additionally, B2985A/B2987A also provides a trend chart of resistivity and test time on the display screen, allowing users to view the resistivity changes before recording the resistivity values.
This technical overview introduces how to use B2985A/87A and 16008B for resistivity measurement.
Note: B2987A offers a built-in rechargeable battery option that can operate normally even without being connected to AC power.

Keysight B2985A/B2987A Electrometer/High Resistance Meter Resistance Measurement
1. Basic knowledge of measurement
There are two basic methods for measuring resistivity: volume and surface.
The following chapter will explain these two methods.
Volume resistivity measurement
The measurement of volume resistivity generally adopts the electrode configuration of the test fixture shown in Figure 1- applying a voltage source Vs to the upper electrode, specifying the high current flowing through the test sample as Im, and then calculating the volume resistivity Rv using the formula Rv=Vs/Im. The high current flowing from the test sample to the protective electrode and the surface current flowing from the upper electrode to the protective electrode both belong to leakage current; However, these currents will enter the low side of Vs and will not affect the magnitude of the ammeter current (Im) used to calculate Rv.
The volume resistivity Rv can be calculated using the formula rv=EAR/STHxRv, where:
EAR=Effective Area
STH=Sample thickness
Surface resistivity measurement
Surface resistivity measurement generally adopts the electrode configuration shown in Figure 2- applying voltage source Vs to the guard ring electrode, the current on the surface of the test sample flows from the guard electrode to the main electrode, and the surface current is specified as Im. The surface resistance Rs can be calculated using the formula Rs=Vs/Im. The current flowing from the protective ring to the upper electrode is leakage current; However, this current will flow into the low side of Vs and will not affect the magnitude of the ammeter current (Im) used to calculate Rv.
The surface resistance can be calculated using the formula rs=EPER/GLENxRs, where:
EPER=Effective perimeter
GLEN=Gap length
B2985/87A can use the built-in MATH function to calculate and display the above parameters.

2. Measurement support function
B2985A and B2987A have multiple characteristics suitable for resistivity measurement.
Measurement time setting:
The measurement of resistivity is usually carried out within a specified time after applying an excitation signal, because the resistivity of insulation materials generally does not quickly converge to a stable value, which requires that any resistivity technical index must correspond to the time point of resistivity measurement. Unless otherwise specified, we usually begin resistivity measurement (according to ASTM D257 standard) 60 seconds after inputting an excitation signal (charged).
B2985A and B2987A allow you to specify the exact time to start measuring after inputting the excitation signal (energized).
Humidity and temperature measurement:
Due to the influence of environmental temperature and humidity on resistivity measurement, it is necessary to record the data of each measurement to facilitate users in comparing the resistivity measurement results of different materials.
B2985A and B2987A allow you to measure and record environmental temperature, humidity, and resistance measurement data.
Trend chart shows:
Due to the fact that resistivity measurement usually changes after the input voltage excitation signal, instruments can display the changes in resistivity from the input excitation signal to the end of the measurement process, which brings convenience to users. B2985A and B2987A allow you to monitor the changes in resistivity over time through charts.
