P.11 Additional graph of
“Resistance-Output voltage Characteristic” for each Voltage range
[Graph of Resistance-Output voltage Characteristic]
Rated current at 500V, 1000V, 2500V, 5000V Ranges : max 1mA or higher
Rated current at 10kV, 12kV Ranges : max 0.5mA
Above graphs show the relations between output voltages and measurement resistances.
*
“Rated measurement current” described in the table at page 11 should be corrected to “Output current”.
P.15 Additional description about current consumption and battery life
 Continuous measurement: No limitation (IR measurement mode)
* recorded data and graph are max 90 min.
Max 90 min (SV measurement mode)
Max 60 min (PI/DAR/DD measurement mode)
 Max current consumption and measurement time while rated currents are maintained.

* Current consumption may exceed above values when low resistances, which influence the output of
rated currents, are measured.
* Measurement time (approx 4 hours) described at page 15 and the Measurement time in above table
are the periods that full-charged battery voltage drops to the lowest level.
* It is recommended to charge the battery with reference to
“7.1 How to charge battery” described in the
manual before stating to use with the instrument since the battery voltage may be low due to
self-discharge.
