No it isn't. All that's needed is to slowly unscrew your drain plug until a slow drip exists. Underneath the drip is a measuring cup.
Stop at 32 ounces / one quart.
Another quicker way is to remove your filter and reinstall it, then do a shorter cycle drip from the drain plug. Most filters hold about a half-quart.
