I’ve recently acquired an uncalibrated Philips PM2534 (edit: the battery-backed factory calibration data was lost due to the battery running out). I’m looking into somehow getting it calibrated. However, the calibration procedure is rather involved, and requires such things as an exact 300V DC (the service manual recommends using a Fuke 5700).

Anybody know of a way to have this multimeter calibrated? I’m a hobbyist and don’t really need such things as traceability and certificates.

Edit: I live in the Netherlands.
