Specifications
Conditions
Background
The specifications are applicable under the following
conditions:
 A 1-year calibration cycle.
 An operating temperature of 18 to 28 ˚C (64.4 to
82.4˚F).
 Relative humidity not exceeding 80%.
 Accuracy is expressed as ±(percentage of reading +
percentage of range).
 The instrument requires 30 minutes warm-up time
and must be operated at the slow measurement rate to
achieve rated accuracy.
 The power cord protective grounding conductor must
be connected to ground.

*When the instrument is set to 50mΩ or 500mΩ ranges, the resistance value
will be changed while connecting or disconnecting the test lead to the panel due
to the different temperature between internal and external parts of the
instrument. Therefore, please wait 1 minute in order to obtain an accurate value
after the test leads have been connected or disconnected.
* When Kelvin clips are used to resume testing after a long period of time,
please wait for a short time to stabilize the measurement.
*Fast and Slow measurement rates have the same specifications. However, the
Slow rate is more accurate as it will correct for any errors associated with
temperature drift that occurs from the difference between the measurement
*
