©2020 Advanced Energy Industries, Inc. The Trek® 156A tests the efficiency of an ionizer’s ion production by timing how long it takes air ions produced to discharge a floating plate that has been pre-charged to either a positive or negative value. The Trek 156A also tests the balance between positive and negative air ions by measuring the offset voltage generated on a floating plate due to an imbalance of positive and negative air ions impinging on the plate from the ionizer. PRODUCT HIGHLIGHTS  Customizable measurement capacitance provides assurance that ESD process needs are met in manufacturing and that there is compliance to ANSI/ESD-STM3.1 and IEC 61340-5-1.  Extremely low offset and drift ensures high accuracy, making it ideal for applications requiring critical ion balance such as GMR and TMR manufacturing areas  Compact and lightweight, for easy portability within a facility  NIST-traceable Certificate of Calibration provided with each unit

APPLICATIONS

Features

Mode Select A three-position toggle switch selects the +Decay, -Decay, or Float mode of operation. This switch is also used in combination with the Test/Reset Control switch to program the START and STOP voltages. Test/Reset Control A momentary toggle switch used in conjunction with the Mode Select switch to program the START and STOP voltages +Decay and -Decay Modes Sets the plate voltage to a value greater than the programmed start voltage and resets the decay timer to zero Float Mode Sets the plate voltage to 0 V ±2 V Plate Voltage Digital Panel Meter 3.5 digit red LED display Range 0 to ±1100 V Resolution 1 V Accuracy Better than 0.1% of full scale ±1 count Decay Time Digital Panel Meter 4-digit red LED display Range 0 to 9999 seconds
