Display

3½ Digit LCD
Range

a. 199.9μs
b. 1999μs
c. 19.99ms
d. 199.9ms
The range is selectable from the rear and can be calibrated by ‘Cell Adj’ at the front for individual range.
Resolution

0.1μs to 0.1ms depending on range selected.
Accuracy

± 0.5% of Full Scale ± 1 Least Significant Digit.
Sensor

Contact Type’ with Cell Constant 1.0
Temperature

Uses PT100, precision temperature sensor (External).
Compensation

The Compensation is internally set at 2% per ˚C
NOTE: If PT100 is not available, then fix a simulated resistance of PT100 @ 25˚C approx. 110Ω. Instrument will not work otherwise.
