    Outside North America, most countries have 50 Hz. Standard three phase voltage systems in most 50 Hz countries are typically 380 V or 400 V. Please call TestEquity for details on voltage reducing transformers for 50 Hz operation. Note that the cooling performance will be reduced by 17% at 50 Hz.

    These tests assume that the Temperature Controller’s setup and tuning values have not been changed from the values as shipped from TestEquity. Also, the Limit Controller high limit must be set to over +85°C (+88°C would be fine), and the low limit set to –75°C.

  • Page 35: How To Inspect The Electrical Compartment

    TestEquity recommends verifying the calibration before attempting to actually perform a calibration. The state-of-the-art instrumentation used in TestEquity chambers is of the highest quality and seldom goes out of calibration. If you try to calibrate the instrumentation before determining that calibration is necessary, you may make it worse if done incorrectly.
