HS-50 Heated Stage
OWNERS MANUAL
Features
The HS-50 Heated Stage is intended for use between 25 and 50
degrees C. The selected temperature is accurately maintained.
The powerful heating element is Bifilar wound to prevent
electromagnetic radiation.
Heating power is electronically switched at zero crossing to prevent
electrical noise generation.
Temperature settings cannot be accidentally changed.
An alarm function can be set to produce a visible and audible alarm
should the stage temperature deviate by more than 1.5 degrees from
the set temperature.
The Liquid Crystal temperature display normally indicates the Actual
Stage Temperature. While the appropriate push button is depressed
it can indicate the Set Temperature or the Alarm Temperature.
