Introduction; Peak Voltage Measurements (V Peak, Optional) - Philips PM2528 Operating Manual

INTRODUCTION
The PM2528 is a microcomputer-controlled, digital, automatic rms multimeter. The type of microcomputer
used is a 8035, extended with 4K external ROM. The instrument can perform the measurements as listed
below.
— direct voltages (V =)
— alternating voltages {V~ }
— alternating voltages including direct voltage component (V ~}
— direct currents {A =)
— alternating currents including direct current component {A ~)
— resistance, in two-wire (QQ 2W) and four-wire (QQ 4W) configuration
— temperature (°C)
— peak voltage measurements (V peak), optional
— high frequency voltage measurements (Vhf}, optional
In the functions V~ , V ~ and A~ the true rms value is measured,
The PM2528 has a 3%, 4% or 5% digit display. The display length depends on the selected function and
measuring mode,
Ranges can be selected manually, automatically or remote via the optional |EC-bus interface,
Measurements can be started with an internal, manual or external facility.
External starting is possible via the external start input, via the JEC-bus interface (optional) or via the BCD
parallel output (optional}.
The optional |EC-bus interface, BCD paralle! output and analog output make the PM2528 fully system-
compatible,
The measuring capabilities can be extended by using the accessories mentioned in the relevant section of this
manual.
The PM2528 is equipped with an internal guard, which is external accessibie.
Therefore very low level signals can be measured with high accuracy.
