Help ! Asahi Pentax Spotmatic Question!

Hi, i recently stumbled upon a 1964 Asahi Pentax Spotmatic and as i was kind of fooling around with it i noticed that when i put in a new battery the little meter inside the view finder didnt work. My question is will this affect how my pictures turn out in any way ? also could i be missing something a step or anything to make it work?
If you know about the Asahi Spotmatic let me know.
thanks so much !

Wrong forum.

If the light meter doesn't work, you won't be able to properly expose your photos, but it doesn't directly affect your photos.

Are you pushing up the light meter switch on the side of the body?

The spotmatic is a fully manual camera, it only relies on the battery for the meter operation. So if the meter is not working you can still take photos just fine, but you will need to find another way to meter. An easy way might be to use another camera to check exposure settings or go by the sunny 16 rule of thumb. Sunny 16 assumes that your exposure settings will be around f/16, ISO 100, 1/125 when conditions are bright and sunny during the day.

Good luck and make sure you check the meter switch that Tuco mentioned. And that you have a suitable battery.

Check the manual in pentax-manuals.com
And also be aware that the batteries can be upside-down. To test set the ISO ring to 100 and the shutter to B; turn the light meter on if it goes down like a rock your battery is good; if it goes up the battery is upside down.
If it stays in the middle there is no meter or no current. Cleanthe battery contacts with the eraser at the end of a pencil and test again.

Are you sure you are using the correct battery?

• Silver oxide batteries that work are: Mallory PX-400 or RM-400-R, Varta V394, Maxell SR936W or SR936SW, Renata 394, or any type 392 equivalent.
• Do not be tempted to use alkaline battery equivalents as they have a much steeper discharge curve. The silver oxide batteries have a flat discharge curve similar to the old mercury batteries.
