Connect the diode to a power supply through a resistor. Turn up the voltage on the power supply while monitoring the voltage across the zener. Once the voltage across the zener stops going up while the power supply voltage is going up, then it is in break down and the voltage across the zerer is the breakdown voltage. You might try a 1000 Ohm resistor to start.
If the breakdown voltage is less than 1 volt then you probably have the diode in forward conduction. Reverse the polarity on the diode.

To measure the Vz experimentally, connect a 1 kohm resistor in series with a zener diode. Now connect a variable dc power supply so that zener diode becomes reverse biased. Put a voltmeter across the zener diode and vary the voltage of the dc power supply.
When the voltage across the zener becomes saturated or fixed, but
voltage across resistor increases with the increase of dc power supply, that is the zener break down voltage. For theoretial equation see -- Solid state electron. devices - BG Streetman
