Characteristic Description
DC offset drift -50 mV/°C or less at output of probe
(results in -0.125 mV/°C or less (2.5 X), or
-0.625 mV/°C or less (12.5 X) displayed on screen)
DC voltage measurement accuracy (referred to input) ±(2% of input + 8.00 mV + 8.00 mV) (2.5 X)
±(2% of input + 36.00 mV + 36.0 mV) (12.5 X)
gain error = ±2% of input voltage
output zero offset (referred to input) =
±8.00 mV (2.5 X)
±36.00 mV (12.5 X)
linearity error = ±1.0% of:
800 mV dynamic range = 8.00 mV (2.5 X)
3.6 V dynamic range = 36.0 mV (12.5 X)
