1. Introduction
1.1. Generalization
The Meter is a battery-operated process maintenace field device which combined both digital-parameter function with
process-signal source together.
Functioning as follows:
Measurement function of TC voltage, DC voltage , Ohms, DC, Continuity and Diode; Data reserving function;
Max. Voltage applied to output terminals: about 32V; Max. current applied to output terminals: about 25mA.
Output function of DC (Constant, Manual-Step and SIMULATE modes)
Loop-circuit testing function; Powering the loop circuit with 24 Voltage and testing the current; Built-in 250Ω HART
loop resistance
Safety: complied with IEC 61010-1 safety requirements for measurement, control and electronic instruments for lab
use.
1.2. Opening the Meter Case
Check the product to see whether it is damaged in the shipment or not. Check the materials to see whether they are the
same as shown in the packing list. Keep the packing materials for late delivery.
Standard and chosen accessories supplied are listed as follows. Chosen ones are bought at purchaser's options.
Standard accessories:

  • Page 2 that may damage your meter. Note - indentifies symbols from which you can understand operation and features of your meter. For related international symbols used by the Meter and the Manual, please read table below for reference. Warning • Do not use the meter if it is damaged. Before using the meter, inspect the case. Look for cracks or missing plastic. Pay particular attention to the insulation surrounding the connectors.
  • Page 3 Fuse Safety rules CAT III - Overvoltage of class three, secondary pollution (according to IEC61010) refers to the level of protection for the pulse compression. Typical installation location includes: distribution of three-phase circuit (including a single commercial lighting circuit) position-fixed equipment; interior lighting equipments in large buildings, lines; industrial field devices.

Measuring loop-circuit current The function may measure current value powered with 24VDC constant voltage. 24V loop-circuit measurement function may test transmitter loop circuit. The meter may be connected to transmitter, but not to transmitter or signal adaptor. Warning Typical value of loop power supply is 24VDC.
  • Page 7 Do not apply any voltage to output terminals except in SIMULATE mode. Any wrong application may damage internal circuit. 2.11. Constant current output (SOURCE mode) • Turn the rotary switch to “”; the screen displays “OUTPUT” and “LOOP POWER”; output is set as 0mA. •...
