Frequently Asked Questions about the Tachometer
Question number FAQ-0918
Please compare the measurement accuracy of TM-3100 and HT-5500.
HT-5500 during use
At 354 r/min measurement
Count error 354 x ±0.02 % ± 1 = ±1.0708 displayed value (in 1 r/min units) accuracy = ±1 r/min
At 8.8 r/min measurement
Count error 88 x ±0.02 % ±1 = ±1.0176 displayed value (0.1 r/min unit) accuracy = ±0.1 r/min
TM-3100 during use
At 354 r/min measurement
Count error 354 x ±0.01 % ± 1 = ±1.0354 Display value (in 1 r/min units) accuracy = ±1 r/min
At 8.8 r/min measurement
Count error 88 x ±0.01 % ±1 = ±1.0088 Display value (0.1 r/min unit) accuracy = ±0.1 r/min
By the way,
at a measurement of 8.80 r/min,
the counting error is 880 x ±0.01 % ±1 = ±1.088 when the displayed value (in 0.01 r/min units) is used, the accuracy = ±0.01 r/min.
