An easy way to determine if the cam chain is excessively loose would be to remove the valve covers, and gently rock the crankshaft (using a socket and short breaker bar) while observing valve movement.
Of course, that method will not give You measurable values, however, it would give You ballpark knowledge as to the general condition of cam chain and tensioning device.
