General Safety Considerations

	Safety Symbol			Definition
				Warning: This is a Safety Class I product
				(provided with a protective earthing
				ground incorporated in the power cord).
				The mains plus shall only be inserted in a
				socket outlet provided with a protective
				earth contact. Any interruption of the
				protective conductor, inside or outside the
				instrument, is likely to make the instrument
				dangerous. Intentional interruption is
				prohibited. DO NOT defeat the earth-
				grounding protection by using an
				extension cable, power cable, or
				autotransformer without a protective
				ground conductor.
				Caution: This instrument is shipped with a
				three-wire power cable, in accordance
				with international safety standards. When
				connected to an appropriate power line
				outlet, this cable grounds the instrument
				cabinet.
				Warning: For indoor use only, do not
				expose to rain.

1.0 Introduction

The ETS-Lindgren

Holaday HI-1710A Microwave Measurement System combines the proven and reliable diode sensing technology of the ETS-Lindgren Holaday Microwave Survey Meters with the digital processing techniques developed for automatic oven scanning.

HI-1710A with

HI-2623 Microwave Oven Probe

HI-1710A Features

HI-1710A Front Panel

Provides time response characteristics, or filters:

raw (Version 3.XX only), fast, and slow. These allow standard

hand scan measurements, as well as the potential for faster scanning similar to that of automated scanning systems.

The unit is shielded with the necessary isolating and attenuating devices to provide immunity to stray leakage of microwave energy.

The circuitry is powered by a regulated supply with normal industrial transient protection devices.

www.ets-lindgren.com	Introduction	9

The diode detection array of eight hot carrier diodes is housed in the large end of the plastic probe assembly. This antenna array has the unique feature of being able to sum microwave electric fields of any plane perpendicular to the axis of the probe. The antenna lobe is also very broad, making it easy to use when measuring leakage around an oven door.

The cone spacer is designed to provide 5-cm spacing (as required by the CDRH performance standard) from the tip of the probe cone to the center of the array. The shape of the cone provides minimum perturbation of the electric field impinging on the diode array.

The probe is attached permanently to the preamplifier assembly by a 9-ft shielded cable. Each detection probe and amplifier assembly is calibrated as a unit and can be used interchangeably with any HI-1710A readout. The digital indicator reads to two or three decimal places from 0 to 9.999 mW/cm2. Temporary over exposure to microwave fields up to 2000 mW/cm2 will not cause probe burnout or damage the instrument or the calibration.

Either auto-range or four ranges with full-scale indications of 1, 2, 5, and 10 mW/cm2 can be selected from the front panel or with a remote serial port command. Selecting the range determines the full-scale setting of the bar graph display located below the digital readout for a continuous analog indication of the measured leakage level.

The audio alarm circuit can be set to any level up to 9.99 mW/cm2. When the level of the microwave leakage exceeds the pre-selected value the audio alarm will sound if the audio is enabled, alerting the operator that the chosen level has been exceeded. For more information about the alarm, see page 30.

Optional External Zero Receptacle

The external zero receptacle will help shield the probe from stray RF fields while being zeroed. Additionally, in high-volume testing situations, the zero receptacle can reduce wear on the ZERO button located on the HI-1710A front panel.

The zero receptacle ships with a 10-foot cable.

For ordering information, see Replacement and Optional Parts on page 15. For information on using the zero receptacle, see Connecting and Using the Zero Receptacle on page 26.

2.0 Maintenance

WARRANTY

Before performing any maintenance, follow the safety information in the ETS-Lindgren Product Information Bulletin included with your shipment.

Maintenance of the HI-1710A is limited to external components such as cables or connectors.

Clean the exterior of the cabinet using a damp cloth and mild cleaner. Always unplug the unit before cleaning.

To prevent electrical shock, do not remove cover.

Warranty may be void if the housing is opened.

If you have any questions concerning maintenance, contact ETS-Lindgren Customer Service.

Software/Firmware Updates (Version 3.XX Only)

Periodically you should check for updates to the software/firmware for your HI-1710A Microwave Measurement System.

Go to www.ets-lindgren.com.

On the Resources menu, click Software/Firmware.

In the Software/Firmware column, look for HI-1710A files. Save the zip file to the desired location on your computer.

In the same section where the zip file is located, click the link to download the installation instructions. Follow those instructions to install the new software/firmware.

www.ets-lindgren.com	Maintenance	13

Replacing the Fuse

Disconnect the HI-1710A from power before replacing a fuse.

If the HI-1710A fails to operate, check for a blown fuse inside the power entry module. A blown fuse must be replaced with the same value and type of fuse, or an unsafe condition may result. Use only 250 Volt, 1.0 Amp, Type T

(5 mm x 20 mm) fuses.

To replace a fuse:

1.Two fuses are located in the fuse drawer in the power input module. Use a screwdriver to open the drawer.

2.The fuse towards the outside of the drawer is the spare. Remove the spare fuse from the module.

3.Replace the blown fuse with the spare fuse.

4.Slide the fuse drawer back into the module. Make sure that the drawer snaps securely into its locked position.

Replacement and Optional Parts

ETS-Lindgren may substitute a similar part or new part number with the same functionality for another part/part number. Contact ETS-Lindgren for questions about part numbers and ordering parts.

Following are the part numbers for ordering replacement or optional parts for the HI-1710A.

Part Description	Part Number
Microwave Oven Probe	HI-2623

The HI-2623 Microwave Oven Probe may be used interchangeably with the HI-1710A. A calibrated assembly may be used to replace the existing probe, eliminating downtime. Many service problems are related to probe or cable damage and can be corrected without sending the HI-1710A for service.

Spacer Cone Kit—Includes 10 cones and 20 shields.	H-540013

To maintain stated accuracy, use only ETS-Lindgren replacement cones.

Zero Receptacle	H-490930

Annual Calibration

See the Product Information Bulletin included with your shipment for information on ETS-Lindgren calibration services.

Service Procedures

The inner case of the HI-1710A is sealed to maintain calibration. Normally, user repair operations are limited to verification of proper input voltage and replacement of the probe/preamplifier assembly.

For the steps to return a system or system component to ETS-Lindgren for service, see the Product Information Bulletin included with your shipment.
