Page 8: Operating Instructions
The Model 212 and 212XL Static Meters are accurate, compact electrostatic field meters used for locating and measuring static charge potentials. The Model 212 is a handy, compact handheld unit which utilizes a 3½-digit LCD digital display readout. Ranging lights assure accurate and repeatable measurements when measuring flat surfaces. - Page 9 For example, at a measurement distance of 3” (76mm), multiply the Model 212 meter reading by 3 to give a range of 0 to 60 kilovolts. Observing the aspect ratio guideline above, the object being measured at this distance should be at least 12”...

Page 13: Calibration And Maintenance
BATTERY REPLACEMENT The Model 212 operates from a standard 9 VDC alkaline battery. Battery life is in excess of 30 hours under normal use. When the battery voltage drops below 6.7 volts, the 212 will indicate low battery by illuminating all of the decimal points on the display. -

Static Meter and adjust the ZERO if necessary. Turn on the calibrated power supply. The Meter should read the applied voltage 5% for the Model 212. For the Model 211, the correct indicator should light. Small adjustments of the Meter distance from the plate will change the reading. -
Page 15: Appendix A - Probes And Detectors
Model 205C, 205C-x1 and 205C-x10 Charged Plate Detectors These charged plate detectors attach to the front of the Model 211 and 212 Static Meter. The standard Model 205C along with the optional 6”x6” Detector Plate is shown in below increases the sensitivity of the measurement system by a factor of 10 and is designed for low voltage measurements up to 2kV with a resolution of 1V.
