ERR002
Zero-Adjust attempted in a continuity test, diode test, or a
frequency measurement
ERR003 Zero-Adjust attempted when an overflow occurs
ERR004
The upper-limit value and lower-limit value in the comparator
settings are reversed.
ERR005 The set clamp cannot be DC-clamped.
ERR006
The comparator was set to continuity test or frequency
measurement.
ERR010 Execution error

Command error
ERR001
ERR200 to 399
Malfunction of the built-in EEPROM. All settings made on the
unit are saved to the built-in EEPROM. The EEPROM is limited
to a certain finite number of write operations. When the life of the
EEPROM has expired, an error is issued.

(2) Measurement of high resistances
Measurements of high resistances are susceptible to the effects of external
noise. To ensure stable measurement values, we recommend using shielded
wires. Connect the outer shield cover to the COM terminal.
(3) AC+DC measurement
This unit cuts off DC components when an AC current is measured. To
measure the true effective value of a waveform with superimposed DC
components, follow the procedure given below:
1. Activate the
V function and measure the AC voltage V
AC
.
2. Activate the V function and measure the DC voltage V
DC
.
3. The true effective value is given by the following equation:
(4) Thermoelectric potentials
Thermoelectric potentials are small electric potentials generated by
differences in temperature at the junction of dissimilar metals. In some cases,
shortly after the test lead is connected to the unit or the test lead is
connected to the sample being measured, a temperature difference may arise.
To ensure precise measurements, allow sufficient time to pass after making
the connections, and start measurement only after temperatures have
stabilized.
