To Select Measurement Rate
The instrument provides three types of measurement rate: 2.5 reading/s, 20
reading/s and 123 reading/s.
2.5 reading/s belongs to “Slow” rate; the mark of Status Bar is “S” and the rate of
refurbishing is 2.5Hz.
20 reading/s belongs to “Middle” rate, the mark of Status Bar is “M” and the rate of
refurbishing is 20Hz.
123 reading/s belongs to “Fast” rate, the mark of Status Bar is “F” and the rate of
refurbishing is 50Hz.
Measurement rate could be controlled by Left and Right direction key. Each press
for the Left key, one level will be increased for rate, vice versa.

Explanations
1. Three reading rates are available for DCV, ACV, DCI, AC and OHM.
2. To set as linkage for both reading resolution and reading (measurement) rate.
 2.5 reading/s belongs to 5.5 digit resolution.
 Both 20 reading/s and 123 reading/s belong to 4.5 digit resolution.
 The reading resolution of Sensor is fixed at 5.5 digit and both “M” and “S” rate
can be chosen.
 The reading resolutions and measurement rates of both Diode and Continuity
are fixed at 4.5 digit and “Fast” respectively.
 The reading resolution and measurement rate of the Freq function are fixed at
5.5 digit and “Slow” respectively.
 The reading resolution and measurement rate of the Cap function are fixed at
3.5 digit and “Slow” respectively.
