Page 3: Section 1: Overview
Section 1: Overview The Kurt J. Lesker KJL-205A, is a rugged, modern vacuum measurement instrument designed to make vacuum measurement easy through the use of a familiar meter movement. Electronically, it is a highly accurate digital vacuum gauge utilizing field- proven thermocouple vacuum sensor technology. -

Page 6: Section 4: Connections
Section 4: Connections The only required connections for operations are power and sensor. The connections are already made in the KJL-205ABM and KJL-205ABM3X units that come fully installed in a metal enclosure, and there is no need to disassemble the unit. The only reason you would disassemble a KJL-205ABM or KJL-205ABM3X enclosure would be to access the analog output and relay connections. -

Step 1. Press the set point switch. This redirects the meter movement to be controlled by the potentiometer adjustment. Step 2. While pressing the set point switch, adjust the set point adjustment until the meter movement indicates the vacuum level at which that you’d like the relay to activate. Step 3. -

Page 10: Notes On Calibration
Notes on calibration The instrument is calibrated in nitrogen, which has thermal properties virtually identical to air. Other gasses will affect the readings by an amount proportional to the thermal conductivity of the gases. In most cases, the gases present in a vacuum system will be air, nitrogen, or oxygen, and no appreciable errors will occur. - Page 11 Input Voltage 5.0 Volts DC external power, 110/220VAC 50-60 Hz using supplied power adapter Maintenance Interval 1-10 years depending on use Overall Dimensions, front panel 2.75 in high, 3.6 in wide, 2.3 inches deep Ambient Operating range 32°F to 100°F Relay Contacts Type C (Normally Open, Common and Normally Closed) 24VDC, 1 Amp...

This 14.696 PSI is equivalent to the pressure produced by a mercury column of approximately 29.92 inches high or .76 meters (~ 3/4 of a yard) or 760 millimeters of mercury. Atmospheric pressure varies greatly with altitude.
