  • Page 6: Introduction

    Section 1 INTRODUCTION This manual provides an overview of the 9334A Series of Air Resistance Standards and also contains the necessary information required to perform a calibration or verification test. General product information, description of case styles and performance specifications are also included.

  • Page 7: Warranty

    Section 1 Warranty Guildline Instruments warrants its products to be free of defects in manufacture and normal operation for a period of two (2) years from the date of purchase, except as otherwise specified. This warranty applies only in the country of original purchase and only to the original purchaser, who is also the end user.

  • Page 8: To Obtain Warranty Or Calibration And Repair Service

    However, if the instrument is purchased within one country and shipped to another, Guildline will only pay for shipping to the original ship to country or customer point. The customer is responsible for paying for the shipping costs to return an item to Guildline.

  • Page 9: Safety Information

    Section 1 Safety Information These Standards can be used with Equipment capable of voltages up to 1000 V. The operator should be aware of the environment in which these standards are used. WARNING: Use caution when working with voltages above 30 V ac rms, 42 V ac peak, or 42 V dc.

  • Page 11 For example, a 9334A-100M is calibated by Guildline with the value reported at 100 V. If this 100M was connected to a Keysight (Aiglent) 3458A, the DMM is only capable of 5 V at 100 M and 1GΩ. This means that there is a 95 V Voltage coefficient minimum that must be added to the expected results when comparing results from the two voltages used.
  • Page 12 Section 2 or an available voltage of 100 V. If the user is not aware of these modes, there is a potential of a 50 ppm error due to selecting the wrong mode of operation on the 8508. Temperatures greatly affect high to ultra high resistance values. In some cases a single degree of temperature can affect a high value resistor by as much as 80% of the standards drift specification.

  • Page 21: Calibration And Performance Verification

    The following section describes the calibration and performance verification procedures for the 9334A Series of Resistance Standards. It is recommended that Resistance Standards be calibrated at 10 mW of power or less. The listed points in Table 2 are for 10 mW of Power for most values.

  • Page 22: Calibration Interval And Performance

    Section 4 4.3 Calibration Interval and Performance It is recommended that the 9334A series be calibrated or verified on the manufacturer’s recommended 12 month interval. As with all resistance standards it is highly recommended that past history be used to determine drift rates. Generally, resistance standards will drift in value more significantly in the first 12 months.
