■DIN RAIL MOUNTING

Set the base socket so that its

DIN rail adaptor is at the bot-

tom. Hang the upper hook at

the rear side of base socket on

the DIN rail and push in the

CHECKING

1) Terminal wiring: Check that all cables are correctly con-

nected according to the connection diagram.

2) Input: Calculate the calibration range and check that the

result is within the usable range.

Calibration Range [W] = Measuring Wattage

(VT Ratio) × (CT Ratio)

3) DC output: Check that the load resistance meets the de-

scribed speciﬁcations.

4) Pulse output: Check that the load connected to the open

collector output is within 35V DC @ 100mA.

ADJUSTMENT PROCEDURE

This unit is calibrated at the factory to meet the ordered

speciﬁcations, therefore you usually do not need any cali-

bration.

For matching the signal to a receiving instrument or in case

of regular calibration, adjust the output as explained in the

following.

■HOW TO CALIBRATE THE DC OUTPUT SIGNAL

Use a signal source and measuring instruments of sufﬁcient

accuracy level. Turn the input signal on and warm up for

more than 10 minutes.

1) ZERO: Apply 0% input and adjust output to 0%.

2) SPAN: Apply 100% input and adjust output to 100%.

3) Check ZERO adjustment again with 0% input.

4) When ZERO value is changed, repeat the above proce-

dure 1) – 3).

MAINTENANCE

Regular calibration procedure is explained below:

■CALIBRATION

Warm up the unit for at least 10 minutes. Apply 0%, 25%,

50%, 75% and 100% input signal. Check that the output

signal for the respective input signal remains within accu-

racy described in the data sheet. When the output is out of

tolerance, recalibrate the unit according to the “ADJUST-

MENT PROCEDURE” explained earlier.
