PPM-50 works on lithium battery. Please make sure battery is mounted properly before use.
When battery is low, low battery indicator will appear on LCD. You can still use PPM-50 as
long as its display on LCD is identifiable. When LCD display becomes dim, laser source
output will become unstable and power meter measurement will be inaccurate. Please
charge as soon as possible when battery is low to ensure accurate measurement.
Please take out the battery if PPM-50 is not in use for a long time.
