  If the alarm is activated on your Phcbi Laboratory Equipment, it could be due to several reasons. First, the chamber temperature might be exceeding the set high or low limit. Check the chamber temperature settings and the high/low limit temperature alarm settings. Also, putting a lot of heat load into the chamber at once can trigger the alarm; the alarm should stop when the chamber temperature decreases. Ensure there isn't an excessive heat source inside. Electromagnetic waves from nearby appliances may also cause this issue, so keep the unit away from such appliances.

  If your Phcbi Laboratory Equipment isn't operating when switched on, the issue could stem from the unit not being properly connected to the power supply, or the power source may not have sufficient capacity. Ensure the unit is correctly connected and that the power supply is adequate. Alternatively, there might be a power failure, a blown fuse, or an activated circuit breaker. Check the power status, the fuse, and the circuit breaker to resolve this.

How to fix a temperature program that isn't working on Phcbi MLR-352-PE?

  Wayne VelasquezAug 29, 2025
  If the temperature isn't changing according to the program you've set on your Phcbi Laboratory Equipment, it might be because the programmed temperature variation exceeds the unit's pull-up/pull-down performance capabilities. Try setting a program that takes the unit's performance into consideration. Also, incorrect high/low limit temperature alarm settings can cause this issue; double-check and correct these settings. Finally, electromagnetic waves from nearby appliances may interfere with the unit's operation, so keep it away from such appliances.
