Multi-Channel Sync Hipot Tester 19020/19020-4/19021/19022/19022-4
Quick Start Guide
7
■ Tester uses a power transformer with 1100VA or above
When the device to be tested draws a great deal of current, the current
(about 10amp) may flow in for more than 10ms before judging for defect item
and cutting off the output current. The same situation may occur before test,
thus it is necessary to watch out the power cord capacity and the connecting
cables used for other instruments or devices.
■ Storage
The temperature and humidity for the Tester is 5°C~35°C, 70% RH in normal.
The operation may malfunction if exceeding the range. Do not mount the
Tester to a fixed place in case it needs to be removed. The storage
temperature for the Tester is from -10°C to 60°C, ≤ 80% RH. If it is not in
use for a long time, please pack it with its original package for storage. For
proper test and safety measures, do not place the Tester under direct
sunlight, high temperature, trembling, humid or dusty area.
■ Warming up
The Tester is activated when power is on; however, in order to meet the
specifications for accuracy please warm it up for 15 minutes or above.
■ Warning label during test
“DANGER – HIGH VOLTAGE TEST IN PROGRESS,
UNAUTHORIZED PERSON KEEP AWAY”
■ Keep test cable away from the panel
Please keep the high voltage cable or the DUT away from the panel at least
30 cm during operation to avoid the display interference caused by high-
voltage discharge.
■ Notices for connecting automated device
(1) The grounding system of the device and the automated station should
be connected together.
(2) Add anti-interference iron core to the high voltage cable and the 2 ends
(device output and DUT) of RTN/LOW test cable with winding at least
1 circle.
(3) The high voltage and RTN/LOW test cable must be separate from the
control cable.
(4) The high voltage and RTN/LOW test cable must keep proper distance
from the scanner panel.
