high-voltage wiring of the subject with good insulation.
4. This meter is provided with an optical fiber interface, through which the current
information measured by the microammeter can be sent to the intelligent dc tester control
box for display (in system Settings, select the microammeter and set it as [optical fiber]).
5. After the high-voltage lead plug is inserted, the internal power is connected, and
the internal power is cut off when it is pulled out. When "LOW BATTERY" is displayed on
the LCD screen, it indicates the BATTERY is under voltage. Please remove the locking
screw from the back cover, remove the back cover, panasonic screw to fix the BATTERY,
and replace the BATTERY.
6. During the DC withstand voltage test of cable or high-voltage capacitor, the
charging current value can be more than twice the rated current, and the meter will not be
damaged.
7. After the DC high voltage test of the test product is completed, discharge the
discharge at the housing of the microammeter with the special discharge rod of HZZGF dc
high voltage test.
Note: special electric discharge shall not touch the high voltage discharge directly, when
the voltage is higher, should make discharging rod tip and the high pressure side keep a
certain distance, to discharge rod tip produce corona discharge, enable participants to the
voltage decline gradually to 20% when the test voltage, reoccupy discharge rod of
microampere meter shell discharge, the last on the ground directly in the subjects.
8. Special attention: do not directly discharge the earth wire on the housing of the high
voltage microammeter, so as to avoid the damage of the high voltage microammeter
caused by the strong impact discharge current.
9. When the power of the microammeter is switched on for 20 minutes and no current
flows, the microammeter will enter low-power standby mode. The LCD screen of the
microammeter displays "SLP" and detects the current every 10 seconds.
