The following parameters are accessible from the Temperature Compensation Setup page:
Note:
1. The temperature probe detects ambient temperature, not DUT surface temperature.
2. Before measurement, warm up the instrument and probe for about half an hour.
3. The temperature probe should be placed as close as possible to the DUT but not in direct contact.
4.2.1 Parameter Settings
Each parameter key opens a numeric keypad to input the corresponding value.
Temperature Correction (TC) Parameters:
 t0 (°C): Reference temperature.
 αt0 (ppm): DUT temperature coefficient of DUT at t0.
Temperature Conversion (∆t) Parameters:
 R1 (Ω): Resistance at the start of the thermal test
 t1 (°C): DUT temperature at the start of the thermal test
 k: Reciprocal of the DUT temperature coefficient at 0 °C
Analog Input Parameters:
 V1 (V): Reference voltage 1
 V2 (V): Reference voltage 2
 T1 (°C): Reference temperature 1
 T2 (°C): Reference temperature 2
4.2.2 TC/∆t
The TC/∆t option allows the user to enable the temperature compensation functions. Touch
the TC/∆t key, the following menu options will be displayed:
 OFF: Disable all temperature compensation functions
 TC: Enable Temperature Correction. See below for details.
 ∆t: Enable Temperature Conversion. See below for details.
