Chapter 1 GENERAL DESCRIPTION Kikusui Model 149-10A High Voltage Digitalmeter measures AC and DC voltages of up to 10 kV, with a high accuracy. As the meter input impedance is as high as 1000MΩ, the meter is best suited for measurement of voltages of high source impedance circuits.
Immediately upon receipt of the device, inspect it for any damage which might have been sustained while in transportation. If any signs of damage are found, contact Kikusui distributor/agent. 2.2 Notes for Use 1. Be sure to connect securely between the meter and the measured voltage source with the supplied cord.

A and B of the measured object are shorted through the earth-ground and the measured object is adversely affected. In order to prevent this, be sure to earth-ground securely the 149-10A and to identify correctly the high voltage and low voltage lines of the measured object (refer to 3.4.1 Measuring Procedure) and to...
For grounding the casing to the earth. Fuse: 0.5 A fuse 3.3 Description of Side Panel CALIBRATION (AC/DC): Semi-fixed resistors for calibration of AC and DC voltages, respectively. Do not touch these resistors except when calibrating the instrument. 149-10A www.valuetronics.com...
2. Connect the AC power cord to an AC power line outlet of the correct voltage, and turn ON the POWER switch. To measure with highest accuracy, warm up the 149-10A for at least 15 minutes. 3. Securely connect the LOW terminal of the front panel to the low line of the measured voltage source using the cord (supplied).
