Has anyone used the MC34161 IC (voltage monitor)?

If so, I'm using them in a power supply that has 12V and 48V outputs. The supply will connect to multiple channel modules, so I'd like to monitor the voltages with LEDs that indicate an "OK" condition. I got the 48V monitor to work correctly, but I think I have the wrong resistor values for the 12V. My question: from the datasheet, is Vth 1.27V? And is Vh = 25mV? I think I'm calculating the wrong resistor values for the 12V monitor. Thanks!!
