3. Intended use

• Measuring and displaying electric parameters in the range of measuring category CAT III for up to 1000 V or CAT IV

for up to 600 V against earth potential, pursuant to EN 61010-1 /UL 61010-1/CAN/CSA-C22.2 NO. 61010-1 and

all lower categories.

• Measurement of direct current up to 1000 V

• Measurement of alternating current up to 1000 V

• Measurement of direct and alternating current up to 10 A or 20 A, short term (10 seconds)

• Frequency measurement from 600 Hz up to 40 MHz (electronic) or from 45 up to 400 Hz (electrical, as a subfunc-

tion)

• Capacity measurement up to 60 mF

• Measurementofresistancesupto60MΩ

• Measurement of temperatures from -40 up to +1000 °C

• Continuitytest(<10Ωacoustic)

• Diode test

• 3-Phase rotating direction display

The measurement functions are selected using the dial switch. Automatic measurement range selection (autorange)

is active in all measurement ranges (except mV, diode test and continuity test).

In the AC voltage and AC current measurement range, true effective measured value (true root mean square; True

RMS) up to a frequency of 400 Hz.

The two current measuring inputs are secured against overload with ceramic high-performance fuses. The voltage in

the measuring circuit must not exceed 1000 V.

The multimeter is operated with a conventional 9 V block battery (type 6F22, NEDA 1604 or same build). The device

mustonlybeoperatedwiththespeciedbatterytype.Arechargeablebatteryshouldnotbeusedduetothelower

capacity.

Automatic deactivation switches off the device after approx. 15 minutes when no button has been pushed on the

device. This prevents premature discharging of the battery. This function can be deactivated.

There is an LED lamp that can be activated and used as a torch at the rear of the device.

The multimeter must not be operated when it is open, i.e. with an open battery compartment or when the battery

compartment lid is missing.

Due to its build, the device corresponds to protection type IP65 and is dust- and water-jet-tight. The meter must not

be used when wet or moist. Protection type IP65 only serves to protect the device.

Measuring in potentially explosive areas (Ex) or damp rooms or under unfavourable ambient conditions is not permit-

ted.Unfavourableambientconditionsare:Moistureorhighhumidity,dustandammablegases,fumesorsolvents,
