Therefore, a measurement of R only very difficult. said that, with some insulation resistance measurements, it takes several hours to a few days for the leakage curre nt to stabilize. This is not practical. To avoid this problem, a method is customarily used in the insulation resistance measurement for convenience to read the resistance value one minute after charging the test voltage to the sample. -

8. REMOTELY CONTROLLED MEASUREMENT A measurement can be remotely controlled by shorting the “G” and “+” terminals of the REMOTE IN of the External Input/Output terminal block on the rear of the unit. When the terminals are shorted by a remote switch, a measurement will start, and when opened the measurement is ended. - Page 51 Note 1: When the measuring time is set with the incorporated timer, the timer has a priority over a remotely controlled switch actuation. When the REMOTE IN “G” and “+” terminals are closed, a measurement will start. The measurement will automatically end when the time set with the timer is up.
