85RF II

High Frequency Probe

Instruction Sheet

Introduction

The 85RF II High Frequency Probe (the Probe) transforms a

dc voltmeter into a high frequency (100 kHz to 500 MHz) ac

voltmeter. Conversion from ac to dc is done on a one-to-one

basis and includes a range of 0.25 V rms to 30 V rms. The

Probe’s dc output is calibrated to be equal to the rms value

of a sine wave input.

X Hazardous voltage.

Do not dispose of this product as

unsorted municipal waste. Go to Fluke’s

website for recycling information.

WXWarning

To prevent possible electrical shock, fire, or personal

injury:

• Examine the case before you use the Product.

Look for cracks or missing plastic. Carefully

look at the insulation around the terminals.

• Limit operation to the specified measurement

category, voltage, or amperage ratings.

• Do not touch voltages >30 V ac rms, 42 V ac

peak, or 60 V dc.

• Do not use the Product around explosive gas,

vapor, or in damp or wet environments.

• Do not use and disable the Product if it is

damaged.

• Use the Product only as specified, or the

protections supplied by the Product can be

compromised.

• Do not exceed the Measurement Category (CAT)

rating of the lowest rated individual component

of a Product, Probe, or accessory.

• Keep fingers behind the finger guards on the

Probes.

• Do not connect directly to mains.

Voltmeter Compatibility

The 85RF II can be used with a dc voltmeter that has an

input resistance of 10 Me, ±10 %. Voltmeters with higher

input resistances are usable if an external shunt is put

across the input terminals. The shunt value is set to

decrease the input resistance to 10 Me.
