Is it reasonable (or normal) to charge extra to calibrate an essential accessory supplied with an instrument?

Dr. David Kirkby from Kirkby Microwave Ltd
The HP/Agilent 4285A LCR meter was supplied as standard with a 100-ohm resistor, P/N 04285-61001. It is a 4-terminal device with 4 BNC connectors on it. It is a furnished accessory, essential to use the 4285A properly, and is only used with the 4285A. (See photo from manual).
I've sent the 4285A LCR meter to Keysight, but they want extra to calibrate the resistor. Does that seem reasonable, and/or normal practice?
I don't know the specifications of the resistor, so can't calibrate it myself. Although I have a 6.5 digit multimeter, the RF properties of this resistor are probably important, as it is used to 30 MHz.
